Use new account assignment APIs for AWS SSO to automate multi-account access

Post Syndicated from Akhil Aendapally original https://aws.amazon.com/blogs/security/use-new-account-assignment-apis-for-aws-sso-to-automate-multi-account-access/

In this blog post, we’ll show how you can programmatically assign and audit access to multiple AWS accounts for your AWS Single Sign-On (SSO) users and groups, using the AWS Command Line Interface (AWS CLI) and AWS CloudFormation.

With AWS SSO, you can centrally manage access and user permissions to all of your accounts in AWS Organizations. You can assign user permissions based on common job functions, customize them to meet your specific security requirements, and assign the permissions to users or groups in the specific accounts where they need access. You can create, read, update, and delete permission sets in one place to have consistent role policies across your entire organization. You can then provide access by assigning permission sets to multiple users and groups in multiple accounts all in a single operation.

AWS SSO recently added new account assignment APIs and AWS CloudFormation support to automate access assignment across AWS Organizations accounts. This release addressed feedback from our customers with multi-account environments who wanted to adopt AWS SSO, but faced challenges related to managing AWS account permissions. To automate the previously manual process and save your administration time, you can now use the new AWS SSO account assignment APIs, or AWS CloudFormation templates, to programmatically manage AWS account permission sets in multi-account environments.

With AWS SSO account assignment APIs, you can now build your automation that will assign access for your users and groups to AWS accounts. You can also gain insights into who has access to which permission sets in which accounts across your entire AWS Organizations structure. With the account assignment APIs, your automation system can programmatically retrieve permission sets for audit and governance purposes, as shown in Figure 1.

Overview

In this walkthrough, we’ll illustrate how to create permission sets, assign permission sets to users and groups in AWS SSO, and grant access for users and groups to multiple AWS accounts by using the AWS Command Line Interface (AWS CLI) and AWS CloudFormation.

To grant user permissions to AWS resources with AWS SSO, you use permission sets. A permission set is a collection of AWS Identity and Access Management (IAM) policies. Permission sets can contain up to 10 AWS managed policies and a single custom policy stored in AWS SSO.

A policy is an object that defines a user’s permissions. Policies contain statements that represent individual access controls (allow or deny) for various tasks. This determines what tasks users can or cannot perform within the AWS account. AWS evaluates these policies when an IAM principal (a user or role) makes a request.

When you provision a permission set in the AWS account, AWS SSO creates a corresponding IAM role on that account, with a trust policy that allows users to assume the role through AWS SSO. With AWS SSO, you can assign more than one permission set to a user in the specific AWS account. Users who have multiple permission sets must choose one when they sign in through the user portal or the AWS CLI. Users will see these as IAM roles.

To learn more about IAM policies, see Policies and permissions in IAM. To learn more about permission sets, see Permission Sets.

Assume you have a company, Example.com, which has three AWS accounts: an organization management account (ExampleOrgMaster), a development account (ExampleOrgDev), and a test account (ExampleOrgTest). Example.com uses AWS Organizations to manage these accounts and has already enabled AWS SSO.

Example.com has the IT security lead, Frank Infosec, who needs PowerUserAccess to the test account (ExampleOrgTest) and SecurityAudit access to the development account (ExampleOrgDev). Alice Developer, the developer, needs full access to Amazon Elastic Compute Cloud (Amazon EC2) and Amazon Simple Storage Service (Amazon S3) through the development account (ExampleOrgDev). We’ll show you how to assign and audit the access for Alice and Frank centrally with AWS SSO, using the AWS CLI.

The flow includes the following steps:

  1. Create three permission sets:
    • PowerUserAccess, with the PowerUserAccess policy attached.
    • AuditAccess, with the SecurityAudit policy attached.
    • EC2-S3-FullAccess, with the AmazonEC2FullAccess and AmazonS3FullAccess policies attached.
  2. Assign permission sets to the AWS account and AWS SSO users:
    • Assign the PowerUserAccess and AuditAccess permission sets to Frank Infosec, to provide the required access to the ExampleOrgDev and ExampleOrgTest accounts.
    • Assign the EC2-S3-FullAccess permission set to Alice Developer, to provide the required permissions to the ExampleOrgDev account.
  3. Retrieve the assigned permissions by using Account Entitlement APIs for audit and governance purposes.

    Note: AWS SSO Permission sets can contain either AWS managed policies or custom policies that are stored in AWS SSO. In this blog we attach AWS managed polices to the AWS SSO Permission sets for simplicity. To help secure your AWS resources, follow the standard security advice of granting least privilege access using AWS SSO custom policy while creating AWS SSO Permission set.

Figure 2: AWS Organizations accounts access for Alice and Frank

To help simplify administration of access permissions, we recommend that you assign access directly to groups rather than to individual users. With groups, you can grant or deny permissions to groups of users, rather than having to apply those permissions to each individual. For simplicity, in this blog you’ll assign permissions directly to the users.

Prerequisites

Before you start this walkthrough, complete these steps:

Use the AWS SSO API from the AWS CLI

In order to call the AWS SSO account assignment API by using the AWS CLI, you need to install and configure AWS CLI v2. For more information about AWS CLI installation and configuration, see Installing the AWS CLI and Configuring the AWS CLI.

Step 1: Create permission sets

In this step, you learn how to create EC2-S3FullAccess, AuditAccess, and PowerUserAccess permission sets in AWS SSO from the AWS CLI.

Before you create the permission sets, run the following command to get the Amazon Resource Name (ARN) of the AWS SSO instance and the Identity Store ID, which you will need later in the process when you create and assign permission sets to AWS accounts and users or groups.

aws sso-admin list-instances

Figure 3 shows the results of running the command.

Figure 3: AWS SSO list instances

Figure 3: AWS SSO list instances

Next, create the permission set for the security team (Frank) and dev team (Alice), as follows.

Permission set for Alice Developer (EC2-S3-FullAccess)

Run the following command to create the EC2-S3-FullAccess permission set for Alice, as shown in Figure 4.

aws sso-admin create-permission-set --instance-arn '<Instance ARN>' --name 'EC2-S3-FullAccess' --description 'EC2 and S3 access for developers'
Figure 4: Creating the permission set EC2-S3-FullAccess

Figure 4: Creating the permission set EC2-S3-FullAccess

Permission set for Frank Infosec (AuditAccess)

Run the following command to create the AuditAccess permission set for Frank, as shown in Figure 5.

aws sso-admin create-permission-set --instance-arn '<Instance ARN>' --name 'AuditAccess' --description 'Audit Access for security team on ExampleOrgDev account'
Figure 5: Creating the permission set AuditAccess

Figure 5: Creating the permission set AuditAccess

Permission set for Frank Infosec (PowerUserAccess)

Run the following command to create the PowerUserAccess permission set for Frank, as shown in Figure 6.

aws sso-admin create-permission-set --instance-arn '<Instance ARN>' --name 'PowerUserAccess' --description 'Power User Access for security team on ExampleOrgDev account'
Figure 6: Creating the permission set PowerUserAccess

Figure 6: Creating the permission set PowerUserAccess

Copy the permission set ARN from these responses, which you will need when you attach the managed policies.

Step 2: Assign policies to permission sets

In this step, you learn how to assign managed policies to the permission sets that you created in step 1.

Attach policies to the EC2-S3-FullAccess permission set

Run the following command to attach the amazonec2fullacess AWS managed policy to the EC2-S3-FullAccess permission set, as shown in Figure 7.

aws sso-admin attach-managed-policy-to-permission-set --instance-arn '<Instance ARN>' --permission-set-arn '<Permission Set ARN>' --managed-policy-arn 'arn:aws:iam::aws:policy/amazonec2fullaccess'
Figure 7: Attaching the AWS managed policy amazonec2fullaccess to the EC2-S3-FullAccess permission set

Figure 7: Attaching the AWS managed policy amazonec2fullaccess to the EC2-S3-FullAccess permission set

Run the following command to attach the amazons3fullaccess AWS managed policy to the EC2-S3-FullAccess permission set, as shown in Figure 8.

aws sso-admin attach-managed-policy-to-permission-set --instance-arn '<Instance ARN>' --permission-set-arn '<Permission Set ARN>' --managed-policy-arn 'arn:aws:iam::aws:policy/amazons3fullaccess'
Figure 8: Attaching the AWS managed policy amazons3fullaccess to the EC2-S3-FullAccess permission set

Figure 8: Attaching the AWS managed policy amazons3fullaccess to the EC2-S3-FullAccess permission set

Attach a policy to the AuditAccess permission set

Run the following command to attach the SecurityAudit managed policy to the AuditAccess permission set that you created earlier, as shown in Figure 9.

aws sso-admin attach-managed-policy-to-permission-set --instance-arn '<Instance ARN>' --permission-set-arn '<Permission Set ARN>' --managed-policy-arn 'arn:aws:iam::aws:policy/SecurityAudit'
Figure 9: Attaching the AWS managed policy SecurityAudit to the AuditAccess permission set

Figure 9: Attaching the AWS managed policy SecurityAudit to the AuditAccess permission set

Attach a policy to the PowerUserAccess permission set

The following command is similar to the previous command; it attaches the PowerUserAccess managed policy to the PowerUserAccess permission set, as shown in Figure 10.

aws sso-admin attach-managed-policy-to-permission-set --instance-arn '<Instance ARN>' --permission-set-arn '<Permission Set ARN>' --managed-policy-arn 'arn:aws:iam::aws:policy/PowerUserAccess'
Figure 10: Attaching AWS managed policy PowerUserAccess to the PowerUserAccess permission set

Figure 10: Attaching AWS managed policy PowerUserAccess to the PowerUserAccess permission set

In the next step, you assign users (Frank Infosec and Alice Developer) to their respective permission sets and assign permission sets to accounts.

Step 3: Assign permission sets to users and groups and grant access to AWS accounts

In this step, you assign the AWS SSO permission sets you created to users and groups and AWS accounts, to grant the required access for these users and groups on respective AWS accounts.

To assign access to an AWS account for a user or group, using a permission set you already created, you need the following:

  • The principal ID (the ID for the user or group)
  • The AWS account ID to which you need to assign this permission set

To obtain a user’s or group’s principal ID (UserID or GroupID), you need to use the AWS SSO Identity Store API. The AWS SSO Identity Store service enables you to retrieve all of your identities (users and groups) from AWS SSO. See AWS SSO Identity Store API for more details.

Use the first two commands shown here to get the principal ID for the two users, Alice (Alice’s user name is [email protected]) and Frank (Frank’s user name is [email protected]).

Alice’s user ID

Run the following command to get Alice’s user ID, as shown in Figure 11.

aws identitystore list-users --identity-store-id '<Identity Store ID>' --filter AttributePath='UserName',AttributeValue='[email protected]'
Figure 11: Retrieving Alice’s user ID

Figure 11: Retrieving Alice’s user ID

Frank’s user ID

Run the following command to get Frank’s user ID, as shown in Figure 12.

aws identitystore list-users --identity-store-id '<Identity Store ID>'--filter AttributePath='UserName',AttributeValue='[email protected]'
Figure 12: Retrieving Frank’s user ID

Figure 12: Retrieving Frank’s user ID

Note: To get the principal ID for a group, use the following command.

aws identitystore list-groups --identity-store-id '<Identity Store ID>' --filter AttributePath='DisplayName',AttributeValue='<Group Name>'

Assign the EC2-S3-FullAccess permission set to Alice in the ExampleOrgDev account

Run the following command to assign Alice access to the ExampleOrgDev account using the EC2-S3-FullAccess permission set. This will give Alice full access to Amazon EC2 and S3 services in the ExampleOrgDev account.

Note: When you call the CreateAccountAssignment API, AWS SSO automatically provisions the specified permission set on the account in the form of an IAM policy attached to the AWS SSO–created IAM role. This role is immutable: it’s fully managed by the AWS SSO, and it cannot be deleted or changed by the user even if the user has full administrative rights on the account. If the permission set is subsequently updated, the corresponding IAM policies attached to roles in your accounts won’t be updated automatically. In this case, you will need to call ProvisionPermissionSet to propagate these updates.

aws sso-admin create-account-assignment --instance-arn '<Instance ARN>' --permission-set-arn '<Permission Set ARN>' --principal-id '<user/group ID>' --principal-type '<USER/GROUP>' --target-id '<AWS Account ID>' --target-type AWS_ACCOUNT
Figure 13: Assigning the EC2-S3-FullAccess permission set to Alice on the ExampleOrgDev account

Figure 13: Assigning the EC2-S3-FullAccess permission set to Alice on the ExampleOrgDev account

Assign the AuditAccess permission set to Frank Infosec in the ExampleOrgDev account

Run the following command to assign Frank access to the ExampleOrgDev account using the EC2-S3- AuditAccess permission set.

aws sso-admin create-account-assignment --instance-arn '<Instance ARN>' --permission-set-arn '<Permission Set ARN>' --principal-id '<user/group ID>' --principal-type '<USER/GROUP>' --target-id '<AWS Account ID>' --target-type AWS_ACCOUNT

Assign the PowerUserAccess permission set to Frank Infosec in the ExampleOrgTest account

Run the following command to assign Frank access to the ExampleOrgTest account using the PowerUserAccess permission set.

aws sso-admin create-account-assignment --instance-arn '<Instance ARN>' --permission-set-arn '<Permission Set ARN>' --principal-id '<user/group ID>' --principal-type '<USER/GROUP>' --target-id '<AWS Account ID>' --target-type AWS_ACCOUNT

To view the permission sets provisioned on the AWS account, run the following command, as shown in Figure 16.

aws sso-admin list-permission-sets-provisioned-to-account --instance-arn '<Instance ARN>' --account-id '<AWS Account ID>'
Figure 16: View the permission sets (AuditAccess and EC2-S3-FullAccess) assigned to the ExampleOrgDev account

Figure 16: View the permission sets (AuditAccess and EC2-S3-FullAccess) assigned to the ExampleOrgDev account

To review the created resources in the AWS Management Console, navigate to the AWS SSO console. In the list of permission sets on the AWS accounts tab, choose the EC2-S3-FullAccess permission set. Under AWS managed policies, the policies attached to the permission set are listed, as shown in Figure 17.

Figure 17: Review the permission set in the AWS SSO console

Figure 18: Review permission set account assignment in the AWS SSO console

Step 4: Audit access

In this step, you learn how to audit access assigned to your users and group by using the AWS SSO account assignment API. In this example, you’ll start from a permission set, review the permissions (AWS-managed policies or a custom policy) attached to the permission set, get the users and groups associated with the permission set, and see which AWS accounts the permission set is provisioned to.

List the IAM managed policies for the permission set

Run the following command to list the IAM managed policies that are attached to a specified permission set, as shown in Figure 19.

aws sso-admin list-managed-policies-in-permission-set --instance-arn '<Instance ARN>' --permission-set-arn '<Permission Set ARN>'
Figure 19: View the managed policies attached to the permission set

Figure 19: View the managed policies attached to the permission set

List the assignee of the AWS account with the permission set

Run the following command to list the assignee (the user or group with the respective principal ID) of the specified AWS account with the specified permission set, as shown in Figure 20.

aws sso-admin list-account-assignments --instance-arn '<Instance ARN>' --account-id '<Account ID>' --permission-set-arn '<Permission Set ARN>'

List the accounts to which the permission set is provisioned

Run the following command to list the accounts that are associated with a specific permission set, as shown in Figure 21.

aws sso-admin list-accounts-for-provisioned-permission-set --instance-arn '<Instance ARN>' --permission-set-arn '<Permission Set ARN>'

In this section of the post, we’ve illustrated how to create a permission set, assign a managed policy to the permission set, and grant access for AWS SSO users or groups to AWS accounts by using this permission set. In the next section, we’ll show you how to do the same using AWS CloudFormation.

Use the AWS SSO API through AWS CloudFormation

In this section, you learn how to use CloudFormation templates to automate the creation of permission sets, attach managed policies, and use permission sets to assign access for a particular user or group to AWS accounts.

Sign in to your AWS Management Console and create a CloudFormation stack by using the following CloudFormation template. For more information on how to create a CloudFormation stack, see Creating a stack on the AWS CloudFormation console.

Cleanup

To delete the resources you created by using the AWS CLI, use these commands.

Run the following command to delete the account assignment.

delete-account-assignment --instance-arn '<Instance ARN>' --target-id '<AWS Account ID>' --target-type 'AWS_ACCOUNT' --permission-set-arn '<PermissionSet ARN>' --principal-type '<USER/GROUP>' --principal-id '<user/group ID>'

After the account assignment is deleted, run the following command to delete the permission set.

delete-permission-set --instance-arn '<Instance ARN>' --permission-set-arn '<PermissionSet ARN>'

To delete the resource that you created by using the CloudFormation template, go to the AWS CloudFormation console. Select the appropriate stack you created, and then choose delete. Deleting the CloudFormation stack cleans up the resources that were created.

Developing enterprise application patterns with the AWS CDK

Post Syndicated from Krishnakumar Rengarajan original https://aws.amazon.com/blogs/devops/developing-application-patterns-cdk/

Enterprises often need to standardize their infrastructure as code (IaC) for governance, compliance, and quality control reasons. You also need to manage and centrally publish updates to your IaC libraries. In this post, we demonstrate how to use the AWS Cloud Development Kit (AWS CDK) to define patterns for IaC and publish them for consumption in controlled releases using AWS CodeArtifact.

AWS CDK is an open-source software development framework to model and provision cloud application resources in programming languages such as TypeScript, JavaScript, Python, Java, and C#/.Net. The basic building blocks of AWS CDK are called constructs, which map to one or more AWS resources, and can be composed of other constructs. Constructs allow high-level abstractions to be defined as patterns. You can synthesize constructs into AWS CloudFormation templates and deploy them into an AWS account.

AWS CodeArtifact is a fully managed service for managing the lifecycle of software artifacts. You can use CodeArtifact to securely store, publish, and share software artifacts. Software artifacts are stored in repositories, which are aggregated into a domain. A CodeArtifact domain allows organizational policies to be applied across multiple repositories. You can use CodeArtifact with common build tools and package managers such as NuGet, Maven, Gradle, npm, yarn, pip, and twine.

Solution overview

In this solution, we complete the following steps:

  1. Create two AWS CDK pattern constructs in Typescript: one for traditional three-tier web applications and a second for serverless web applications.
  2. Publish the pattern constructs to CodeArtifact as npm packages. npm is the package manager for Node.js.
  3. Consume the pattern construct npm packages from CodeArtifact and use them to provision the AWS infrastructure.

We provide more information about the pattern constructs in the following sections. The source code mentioned in this blog is available in GitHub.

Note: The code provided in this blog post is for demonstration purposes only. You must ensure that it meets your security and production readiness requirements.

Traditional three-tier web application construct

The first pattern construct is for a traditional three-tier web application running on Amazon Elastic Compute Cloud (Amazon EC2), with AWS resources consisting of Application Load Balancer, an Autoscaling group and EC2 launch configuration, an Amazon Relational Database Service (Amazon RDS) or Amazon Aurora database, and AWS Secrets Manager. The following diagram illustrates this architecture.

 

Traditional stack architecture

Serverless web application construct

The second pattern construct is for a serverless application with AWS resources in AWS Lambda, Amazon API Gateway, and Amazon DynamoDB.

Serverless application architecture

Publishing and consuming pattern constructs

Both constructs are written in Typescript and published to CodeArtifact as npm packages. A semantic versioning scheme is used to version the construct packages. After a package gets published to CodeArtifact, teams can consume them for deploying AWS resources. The following diagram illustrates this architecture.

Pattern constructs

Prerequisites

Before getting started, complete the following steps:

  1. Clone the code from the GitHub repository for the traditional and serverless web application constructs:
    git clone https://github.com/aws-samples/aws-cdk-developing-application-patterns-blog.git
    cd aws-cdk-developing-application-patterns-blog
  2. Configure AWS Identity and Access Management (IAM) permissions by attaching IAM policies to the user, group, or role implementing this solution. The following policy files are in the iam folder in the root of the cloned repo:
    • BlogPublishArtifacts.json – The IAM policy to configure CodeArtifact and publish packages to it.
    • BlogConsumeTraditional.json – The IAM policy to consume the traditional three-tier web application construct from CodeArtifact and deploy it to an AWS account.
    • PublishArtifacts.json – The IAM policy to consume the serverless construct from CodeArtifact and deploy it to an AWS account.

Configuring CodeArtifact

In this step, we configure CodeArtifact for publishing the pattern constructs as npm packages. The following AWS resources are created:

  • A CodeArtifact domain named blog-domain
  • Two CodeArtifact repositories:
    • blog-npm-store – For configuring the upstream NPM repository.
    • blog-repository – For publishing custom packages.

Deploy the CodeArtifact resources with the following code:

cd prerequisites/
rm -rf package-lock.json node_modules
npm install
cdk deploy --require-approval never
cd ..

Log in to the blog-repository. This step is needed for publishing and consuming the npm packages. See the following code:

aws codeartifact login \
     --tool npm \
     --domain blog-domain \
     --domain-owner $(aws sts get-caller-identity --output text --query 'Account') \
     --repository blog-repository

Publishing the pattern constructs

  1. Change the directory to the serverless construct:
    cd serverless
  2. Install the required npm packages:
    rm package-lock.json && rm -rf node_modules
    npm install
    
  3. Build the npm project:
    npm run build
  4. Publish the construct npm package to the CodeArtifact repository:
    npm publish

    Follow the previously mentioned steps for building and publishing a traditional (classic Load Balancer plus Amazon EC2) web app by running these commands in the traditional directory.

    If the publishing is successful, you see messages like the following screenshots. The following screenshot shows the traditional infrastructure.

    Successful publishing of Traditional construct package to CodeArtifact

    The following screenshot shows the message for the serverless infrastructure.

    Successful publishing of Serverless construct package to CodeArtifact

    We just published version 1.0.1 of both the traditional and serverless web app constructs. To release a new version, we can simply update the version attribute in the package.json file in the traditional or serverless folder and repeat the last two steps.

    The following code snippet is for the traditional construct:

    {
        "name": "traditional-infrastructure",
        "main": "lib/index.js",
        "files": [
            "lib/*.js",
            "src"
        ],
        "types": "lib/index.d.ts",
        "version": "1.0.1",
    ...
    }

    The following code snippet is for the serverless construct:

    {
        "name": "serverless-infrastructure",
        "main": "lib/index.js",
        "files": [
            "lib/*.js",
            "src"
        ],
        "types": "lib/index.d.ts",
        "version": "1.0.1",
    ...
    }

Consuming the pattern constructs from CodeArtifact

In this step, we demonstrate how the pattern constructs published in the previous steps can be consumed and used to provision AWS infrastructure.

  1. From the root of the GitHub package, change the directory to the examples directory containing code for consuming traditional or serverless constructs.To consume the traditional construct, use the following code:
    cd examples/traditional

    To consume the serverless construct, use the following code:

    cd examples/serverless
  2. Open the package.json file in either directory and note that the packages and versions we consume are listed in the dependencies section, along with their version.
    The following code shows the traditional web app construct dependencies:

    "dependencies": {
        "@aws-cdk/core": "1.30.0",
        "traditional-infrastructure": "1.0.1",
        "aws-cdk": "1.47.0"
    }

    The following code shows the serverless web app construct dependencies:

    "dependencies": {
        "@aws-cdk/core": "1.30.0",
        "serverless-infrastructure": "1.0.1",
        "aws-cdk": "1.47.0"
    }
  3. Install the pattern artifact npm package along with the dependencies:
    rm package-lock.json && rm -rf node_modules
    npm install
    
  4. As an optional step, if you need to override the default Lambda function code, build the npm project. The following commands build the Lambda function source code:
    cd ../override-serverless
    npm run build
    cd -
  5. Bootstrap the project with the following code:
    cdk bootstrap

    This step is applicable for serverless applications only. It creates the Amazon Simple Storage Service (Amazon S3) staging bucket where the Lambda function code and artifacts are stored.

  6. Deploy the construct:
    cdk deploy --require-approval never

    If the deployment is successful, you see messages similar to the following screenshots. The following screenshot shows the traditional stack output, with the URL of the Load Balancer endpoint.

    Traditional CloudFormation stack outputs

    The following screenshot shows the serverless stack output, with the URL of the API Gateway endpoint.

    Serverless CloudFormation stack outputs

    You can test the endpoint for both constructs using a web browser or the following curl command:

    curl <endpoint output>

    The traditional web app endpoint returns a response similar to the following:

    [{"app": "traditional", "id": 1605186496, "purpose": "blog"}]

    The serverless stack returns two outputs. Use the output named ServerlessStack-v1.Api. See the following code:

    [{"purpose":"blog","app":"serverless","itemId":"1605190688947"}]

  7. Optionally, upgrade to a new version of pattern construct.
    Let’s assume that a new version of the serverless construct, version 1.0.2, has been published, and we want to upgrade our AWS infrastructure to this version. To do this, edit the package.json file and change the traditional-infrastructure or serverless-infrastructure package version in the dependencies section to 1.0.2. See the following code example:

    "dependencies": {
        "@aws-cdk/core": "1.30.0",
        "serverless-infrastructure": "1.0.2",
        "aws-cdk": "1.47.0"
    }

    To update the serverless-infrastructure package to 1.0.2, run the following command:

    npm update

    Then redeploy the CloudFormation stack:

    cdk deploy --require-approval never

Cleaning up

To avoid incurring future charges, clean up the resources you created.

  1. Delete all AWS resources that were created using the pattern constructs. We can use the AWS CDK toolkit to clean up all the resources:
    cdk destroy --force

    For more information about the AWS CDK toolkit, see Toolkit reference. Alternatively, delete the stack on the AWS CloudFormation console.

  2. Delete the CodeArtifact resources by deleting the CloudFormation stack that was deployed via AWS CDK:
    cd prerequisites
    cdk destroy –force
    

Conclusion

In this post, we demonstrated how to publish AWS CDK pattern constructs to CodeArtifact as npm packages. We also showed how teams can consume the published pattern constructs and use them to provision their AWS infrastructure.

This mechanism allows your infrastructure for AWS services to be provisioned from the configuration that has been vetted for quality control and security and governance checks. It also provides control over when new versions of the pattern constructs are released, and when the teams consuming the constructs can upgrade to the newly released versions.

Integrating AWS CloudFormation Guard into CI/CD pipelines

Post Syndicated from Sergey Voinich original https://aws.amazon.com/blogs/devops/integrating-aws-cloudformation-guard/

In this post, we discuss and build a managed continuous integration and continuous deployment (CI/CD) pipeline that uses AWS CloudFormation Guard to automate and simplify pre-deployment compliance checks of your AWS CloudFormation templates. This enables your teams to define a single source of truth for what constitutes valid infrastructure definitions, to be compliant with your company guidelines and streamline AWS resources’ deployment lifecycle.

We use the following AWS services and open-source tools to set up the pipeline:

Solution overview

The CI/CD workflow includes the following steps:

  1. A code change is committed and pushed to the CodeCommit repository.
  2. CodePipeline automatically triggers a CodeBuild job.
  3. CodeBuild spins up a compute environment and runs the phases specified in the buildspec.yml file:
  4. Clone the code from the CodeCommit repository (CloudFormation template, rule set for CloudFormation Guard, buildspec.yml file).
  5. Clone the code from the CloudFormation Guard repository on GitHub.
  6. Provision the build environment with necessary components (rust, cargo, git, build-essential).
  7. Download CloudFormation Guard release from GitHub.
  8. Run a validation check of the CloudFormation template.
  9. If the validation is successful, pass the control over to CloudFormation and deploy the stack. If the validation fails, stop the build job and print a summary to the build job log.

The following diagram illustrates this workflow.

Optional CodeCommit Repository Structure

The following screenshot shows a potential CodeCommit repository structure.

Creating a CodeBuild project

Our CodeBuild project orchestrates around CloudFormation Guard and runs validation checks of our CloudFormation templates as a phase of the CI process.

  1. On the CodeBuild console, choose Build projects.
  2. Choose Create build projects.
  3. For Project name, enter your project name.
  4. For Description, enter a description.
AWS CodeBuild

Create CodeBuild Project

  1. For Source provider, choose AWS CodeCommit.
  2. For Repository, choose the CodeCommit repository you created in the previous step.
AWS CodeBuild

Define the source for your CodeBuild Project

To setup CodeBuild environment we will use managed image based on Ubuntu 18.04

  1. For Environment Image, select Managed image.
  2. For Operating system, choose Ubuntu.
  3. For Service role¸ select New service role.
  4. For Role name, enter your service role name.
CodeBuild Environment

Setup the environment, the OS image and other settings for the CodeBuild

  1. Leave the default settings for additional configuration, buildspec, batch configuration, artifacts, and logs.

You can also use CodeBuild with custom build environments to help you optimize billing and improve the build time.

Creating IAM roles and policies

Our CI/CD pipeline needs two AWS Identity and Access Management (IAM) roles to run properly: one role for CodePipeline to work with other resources and services, and one role for AWS CloudFormation to run the deployments that passed the validation check in the CodeBuild phase.

Creating permission policies

Create your permission policies first. The following code is the policy in JSON format for CodePipeline:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": [
                "codecommit:UploadArchive",
                "codecommit:CancelUploadArchive",
                "codecommit:GetCommit",
                "codecommit:GetUploadArchiveStatus",
                "codecommit:GetBranch",
                "codestar-connections:UseConnection",
                "codebuild:BatchGetBuilds",
                "codedeploy:CreateDeployment",
                "codedeploy:GetApplicationRevision",
                "codedeploy:RegisterApplicationRevision",
                "codedeploy:GetDeploymentConfig",
                "codedeploy:GetDeployment",
                "codebuild:StartBuild",
                "codedeploy:GetApplication",
                "s3:*",
                "cloudformation:*",
                "ec2:*"
            ],
            "Resource": "*"
        },
        {
            "Sid": "VisualEditor1",
            "Effect": "Allow",
            "Action": "iam:PassRole",
            "Resource": "*",
            "Condition": {
                "StringEqualsIfExists": {
                    "iam:PassedToService": [
                        "cloudformation.amazonaws.com",
                        "ec2.amazonaws.com"
                    ]
                }
            }
        }
    ]
}

To create your policy for CodePipeline, run the following CLI command:

aws iam create-policy --policy-name CodePipeline-Cfn-Guard-Demo --policy-document file://CodePipelineServiceRolePolicy_example.json

Capture the policy ARN that you get in the output to use in the next steps.

The following code is the policy in JSON format for AWS CloudFormation:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": "iam:CreateServiceLinkedRole",
            "Resource": "*",
            "Condition": {
                "StringEquals": {
                    "iam:AWSServiceName": [
                        "autoscaling.amazonaws.com",
                        "ec2scheduled.amazonaws.com",
                        "elasticloadbalancing.amazonaws.com"
                    ]
                }
            }
        },
        {
            "Sid": "VisualEditor1",
            "Effect": "Allow",
            "Action": [
                "s3:GetObjectAcl",
                "s3:GetObject",
                "cloudwatch:*",
                "ec2:*",
                "autoscaling:*",
                "s3:List*",
                "s3:HeadBucket"
            ],
            "Resource": "*"
        }
    ]
}

Create the policy for AWS CloudFormation by running the following CLI command:

aws iam create-policy --policy-name CloudFormation-Cfn-Guard-Demo --policy-document file://CloudFormationRolePolicy_example.json

Capture the policy ARN that you get in the output to use in the next steps.

Creating roles and trust policies

The following code is the trust policy for CodePipeline in JSON format:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "Service": "codepipeline.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}

Create your role for CodePipeline with the following CLI command:

aws iam create-role --role-name CodePipeline-Cfn-Guard-Demo-Role --assume-role-policy-document file://RoleTrustPolicy_CodePipeline.json

Capture the role name for the next step.

The following code is the trust policy for AWS CloudFormation in JSON format:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "",
      "Effect": "Allow",
      "Principal": {
        "Service": "cloudformation.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}

Create your role for AWS CloudFormation with the following CLI command:

aws iam create-role --role-name CF-Cfn-Guard-Demo-Role --assume-role-policy-document file://RoleTrustPolicy_CloudFormation.json

Capture the role name for the next step.

 

Finally, attach the permissions policies created in the previous step to the IAM roles you created:

aws iam attach-role-policy --role-name CodePipeline-Cfn-Guard-Demo-Role  --policy-arn "arn:aws:iam::<AWS Account Id >:policy/CodePipeline-Cfn-Guard-Demo"

aws iam attach-role-policy --role-name CF-Cfn-Guard-Demo-Role  --policy-arn "arn:aws:iam::<AWS Account Id>:policy/CloudFormation-Cfn-Guard-Demo"

Creating a pipeline

We can now create our pipeline to assemble all the components into one managed, continuous mechanism.

  1. On the CodePipeline console, choose Pipelines.
  2. Choose Create new pipeline.
  3. For Pipeline name, enter a name.
  4. For Service role, select Existing service role.
  5. For Role ARN, choose the service role you created in the previous step.
  6. Choose Next.
CodePipeline Setup

Setting Up CodePipeline environment

  1. In the Source section, for Source provider, choose AWS CodeCommit.
  2. For Repository name¸ enter your repository name.
  3. For Branch name, choose master.
  4. For Change detection options, select Amazon CloudWatch Events.
  5. Choose Next.
AWS CodePipeline Source

Adding CodeCommit to CodePipeline

  1. In the Build section, for Build provider, choose AWS CodeBuild.
  2. For Project name, choose the CodeBuild project you created.
  3. For Build type, select Single build.
  4. Choose Next.
CodePipeline Build Stage

Adding Build Project to Pipeline Stage

Now we will create a deploy stage in our CodePipeline to deploy CloudFormation templates that passed the CloudFormation Guard inspection in the CI stage.

  1. In the Deploy section, for Deploy provider, choose AWS CloudFormation.
  2. For Action mode¸ choose Create or update stack.
  3. For Stack name, choose any stack name.
  4. For Artifact name, choose BuildArtifact.
  5. For File name, enter the CloudFormation template name in your CodeCommit repository (In case of our demo it is cfn_template_file_example.yaml).
  6. For Role name, choose the role you created earlier for CloudFormation.
CodePipeline - Deploy Stage

Adding deploy stage to CodePipeline

22. In the next step review your selections for the pipeline to be created. The stages and action providers in each stage are shown in the order that they will be created. Click Create pipeline. Our CodePipeline is ready.

Validating the CI/CD pipeline operation

Our CodePipeline has two basic flows and outcomes. If the CloudFormation template complies with our CloudFormation Guard rule set file, the resources in the template deploy successfully (in our use case, we deploy an EC2 instance with an encrypted EBS volume).

CloudFormation Deployed

CloudFormation Console

If our CloudFormation template doesn’t comply with the policies specified in our CloudFormation Guard rule set file, our CodePipeline stops at the CodeBuild step and you see an error in the build job log indicating the resources that are non-compliant:

[EBSVolume] failed because [Encrypted] is [false] and the permitted value is [true]
[EC2Instance] failed because [t3.2xlarge] is not in [t2.micro,t3.nano,t3.micro] for [InstanceType]
Number of failures: 2

Note: To demonstrate the above functionality I changed my CloudFormation template to use unencrypted EBS volume and switched the EC2 instance type to t3.2xlarge which do not adhere to the rules that we specified in the Guard rule set file

Cleaning up

To avoid incurring future charges, delete the resources that we have created during the walkthrough:

  • CloudFormation stack resources that were deployed by the CodePipeline
  • CodePipeline that we have created
  • CodeBuild project
  • CodeCommit repository

Conclusion

In this post, we covered how to integrate CloudFormation Guard into CodePipeline and fully automate pre-deployment compliance checks of your CloudFormation templates. This allows your teams to have an end-to-end automated CI/CD pipeline with minimal operational overhead and stay compliant with your organizational infrastructure policies.

Enhance programmatic access for IAM users using a YubiKey for multi-factor authentication

Post Syndicated from Edouard Kachelmann original https://aws.amazon.com/blogs/security/enhance-programmatic-access-for-iam-users-using-yubikey-for-multi-factor-authentication/

Organizations are increasingly providing access to corporate resources from employee laptops and are required to apply the correct permissions to these computing devices to make sure that secrets and sensitive data are adequately protected. The combination of Amazon Web Services (AWS) long-term credentials and a YubiKey security token for multi-factor authentication (MFA) is an option for providing secure programmatic access to AWS for organizations that aren’t yet ready or able to use identity federation. For example, a user should be able to list AWS Identity and Access Management (IAM) roles with their default programmatic access, but would be required to provide MFA to assume an IAM role.

In this blog post, we show you how to use a YubiKey token for MFA with the AWS Command Line Interface (AWS CLI) to create temporary credentials with the permissions that developers need to perform tasks. The user will configure the long-term credentials and then temporarily assume a role with broader permissions by using MFA when needed. MFA adds extra security, because it requires users to provide second-factor authentication from an AWS-supported MFA mechanism in addition to static security credentials such as their user name and password.

The goal for any organization is to move to the recommended best practices for allowing individual programmatic access that include using temporary security credentials that aren’t stored with the user, but are generated dynamically and provided to the user when requested, such as identity federation due to the temporary nature of those credentials. If your organization uses AWS Single Sign-On (AWS SSO) along with an identity provider (IdP) such as Okta, Azure Active Directory (AD), or AWS Managed Microsoft AD, you can then use the instructions from this earlier blog post to leverage the AWS CLI v2 native integration with AWS SSO and take advantage of the multi-factor authentication support of your IdP.

Overview

This post describes the configuration of IAM users and roles and initialization of the YubiKey token as an MFA device by an administrator, and then how developers can use the YubiKey device to retrieve temporary credentials and assume a role with elevated permissions within the AWS CLI.

The overall process flow looks like this:

  1. Create an IAM user with programmatic access, MFA, and a policy that allows you to assume a more privileged IAM role. The user will retrieve a Time-based One-time Password (TOTP) token code by using a YubiKey as MFA.
  2. Assume the more privileged role, which is restricted by an MFA conditional, by using the TOTP token code.

Figure 1 shows the steps of the process.

Figure 1: A visual overview of the steps to assume roles with elevated permissions by using a YubiKey for MFA

Figure 1: A visual overview of the steps to assume roles with elevated permissions by using a YubiKey for MFA

Prerequisites

To get started you need:

  • An AWS account.
  • A YubiKey (available on Amazon.com). YubiKey 4 and 5 series are compatible, because they support the required OATH application.

    Note: The Yubico Security Keys (the blue tokens) aren’t supported, because they lack the OATH application. If you already have a corporate YubiKey device, this capability might have been disabled.

  • To complete the process for:

Notes:

  • AWS CLI v2 doesn’t yet support Universal 2nd factor (U2F) MFA. As a workaround, we use a YubiKey as a virtual device MFA.
  • OATH (Initiative for Open Authentication) is an organization that specifies two open authentication standards: TOTP and HMAC-based One-time Password (HOTP). For this solution, we use the TOTP standard.

Getting started

Initializing YubiKey for MFA

The following steps show you, as cloud administrator, how to initialize the YubiKey as a virtual MFA device and configure an IAM user that can assume a role with elevated permissions, on the condition that the user is using an MFA device. In this example, your developers will assume a role with permissions to access Amazon Elastic Compute Cloud (Amazon EC2).

To configure the IAM user and initialize the YubiKey device as MFA

  1. Create a role with elevated permissions that your developers can assume.
    1. Sign in to the AWS IAM console, and in the right-hand pane, choose Roles. Then choose Create role.

      Figure 2: Create a role in the IAM console

      Figure 2: Create a role in the IAM console

    2. For the type of trusted entity, choose Another AWS account. Enter your account ID, which you can find by using these methods, described in the IAM User Guide. Choose Next:Permissions.

      Figure 3: Select the type of trusted entity and provide the account ID

    3. Search for the AmazonEC2FullAccess policy, and select the check box next to it. Choose Next:Tags, and add relevant tags if needed. Choose Next:Review.
    4. Name the role developer-ec2-mfa, and then choose Create role.
    5. Go back to the role you just created. Change the maximum session duration value to limit how long the developer’s session can be valid after assuming the role. For this example, we set the duration to 1 hour (3,600 seconds) by using a custom value. Limit this duration to abide by your organization’s recommended authentication time.
    6. Take note of the Amazon Resource Name (ARN) for the new role as shown on the summary page.

      Figure 4: Summary page of the new role

      Figure 4: Summary page of the new role

  2. Create a new IAM policy that provides a limited scope of actions for users when they use their long-term credentials.
    1. Navigate to the AWS IAM console, and in the navigation pane, choose Policies. Choose Create policy.

      Figure 5: Create a policy in the IAM console

      Figure 5: Create a policy in the IAM console

    2. Because we’ve already written the policy in JSON, you don’t need to use the Visual Editor, so you can choose the JSON tab and paste the content of the following JSON policy document (remember to replace the placeholder for the role ARN).Following the least privilege approach, add only the Amazon Resource Names (ARNs) of the role or roles with required elevated permissions that the developer will be able to assume. In this case, use the developer-ec2-mfa ARN for the role that you created previously.
      {
         "Version": "2012-10-17",
         "Statement": [
            {
               "Sid": "",
               "Effect": "Allow",
               "Action": "sts:AssumeRole",
               "Resource": <Elevated Role ARN(s)>,
               "Condition": {
                  "Bool": {
                     "aws:multifactorAuthPresent": true
                  }
               }
            }
         ]
      }
      

      Note: The condition “aws:MultiFactorAuthPresent”: “true” requires that the user who assumes the role has been authenticated with an AWS MFA device.

    3. Choose Review policy.
    4. Name the policy yubi-policy-mfa-level-one. Choose Create policy.
  3. Create a new IAM group that lets you specify permissions for multiple users and makes it easier to manage the permissions for those users.
    1. Navigate to the IAM console, and in the navigation pane, choose Groups. Choose Create New Group.

      Figure 6: Create a group in the IAM console

      Figure 6: Create a group in the IAM console

    2. Enter developers-mfa as the group name. Choose Next Step.
    3. On the Attach Policy screen, in the filter box, search for the policy yubi-policy-mfa-level-one that you created in the previous step. Make sure you select the check box next to the policy, and then choose Next Step.

      Figure 7: Attach the policy to the IAM group

      Figure 7: Attach the policy to the IAM group

    4. Review the group information, and then choose Create Group.
  4. Create a user in IAM for the developer using the AWS CLI.
    1. Navigate to the IAM console and in the navigation pane, choose Users. Choose Add user.
    2. On the Add user screen, enter the name for your user. In this example, our developer is named JohnDoe. For Access type, select the check box next to Programmatic access. Choose Next: Permissions.

      Figure 8: Create an IAM user with programmatic access

      Figure 8: Create an IAM user with programmatic access

    3. For permissions, select Add user to group, and select the developers-mfa group. Choose Next: Tags.
    4. Add the relevant tags if needed, and then choose Next: Review.
    5. Review the user configuration, and then choose Create user.
    6. Make sure you save the access key ID and secret access key to share with your user. Choose Close.
  5. Assign an MFA device to the user.
    1. Go back to the Users section of the IAM console. Choose the IAM user that you created previously, and go to the Security credentials tab. For Assigned MFA device, choose Manage.

      Figure 9: Assign MFA device to the IAM user

      Figure 9: Assign MFA device to the IAM user

    2. Select Virtual MFA device, because the AWS CLI doesn’t yet support U2F MFA. Choose Continue.

      Figure 10: Select the Virtual MFA device type

      Figure 10: Select the Virtual MFA device type

    3. Instead of using the QR code, choose Show secret key.

      Note: The secret key is a randomly generated string shared between IAM and the physical YubiKey. It is used to generate a one-time password using a hash function with the current timestamp.

       

      Figure 11: Retrieve the secret key on the virtual MFA device configuration page

      Figure 11: Retrieve the secret key on the virtual MFA device configuration page

    4. Copy the secret key to use in the next step as the MFA_SECRET to configure the MFA device.
  6. To obtain the TOTP token codes from the YubiKey to synchronize the key with the IAM user, do the following.
    1. Insert the YubiKey token in your USB port, and verify that the OATH application is enabled for your YubiKey by running the following command and looking for Enabled USB interfaces: OTP+FIDO+CCID in the output.
      $ ykman info
      
      Device type: YubiKey 5 NFC
      Serial number: 123456789
      Firmware version: 5.2.4
      Form factor: Keychain (USB-A)
      Enabled USB interfaces: OTP+FIDO+CCID
      NFC interface is enabled.
      
      Applications USB NFC
      OTP Enabled Enabled
      FIDO U2F Enabled Enabled
      OpenPGP Enabled Enabled
      PIV Enabled Enabled
      OATH Enabled Enabled
      FIDO2 Enabled Enabled
      

    2. For each MFA device, you need to generate a unique identifier that will be used during the process. We recommend that you create this identifier based on the ARN of the IAM user, by using the following template.
      arn:aws:iam::<ACCOUNT_ID>:mfa/<IAM_USERNAME>
      

    3. Add a new credential to your YubiKey based on the MFA device ARN. Use the MFA_SECRET that you copied in the previous step (step 5).
      ykman oath add -t arn:aws:iam::<ACCOUNT_ID>:mfa/<IAM_USERNAME> <MFA_SECRET>
      

    4. Obtain two TOTP token codes by using the following command (remember to replace the placeholder for the <MFA device ARN>). Wait up to 30 seconds for the device to generate the second token code (you will be prompted to touch the token).
      ykman oath code <MFA device ARN>
      

    5. After obtaining each of the TOTP token codes, go back to the IAM console where you were setting up the virtual MFA device, and enter the code in the MFA code box. After entering the two MFA codes, choose Assign MFA.

      Figure 12: Enter the two consecutive YubiKey codes in the virtual MFA device configuration page

      Figure 12: Enter the two consecutive YubiKey codes in the virtual MFA device configuration page

  7. You can then provide the following information to your developer:
    1. The YubiKey device along with the generated MFA device ARN
    2. The ARNs for the roles that will be assumed
    3. The long-term AWS credentials

Assuming a role with the YubiKey as MFA

The following steps show how you, as a developer, can retrieve temporary credentials using the YubiKey device as MFA, and assume a role with wider permissions. You can do this after the YubiKey device, one or more role ARNs, and long-term credentials have been shared with you by the cloud administrator.

To assume a role with broader permissions by using YubiKey

  1. As part of the prerequisites, you should have the AWS CLI v2 already installed. Now configure the default profile with the long-term credentials provided by your cloud administrator, by using the following command.
    $ aws configure
    
    AWS Access Key ID [None]: <Enter your AWS access key>
    AWS Secret Access Key [None]: <Enter your AWS secret access key>
    Default region name [None]: <Enter your AWS default region>
    Default output format [None]: <Enter your output default format>
    

  2. Obtain a TOTP code from YubiKey (you will be prompted to touch the token). Submit your request immediately after generating the codes. If you generate the codes and then wait too long to submit the request, the code won’t be valid anymore.
    ykman oath code arn:aws:iam::<ACCOUNT_ID>:mfa/<IAM_USERNAME>
    

  3. Using the MFA token code you obtained by using the YubiKey, assume the relevant role that will provide access to larger permissions. In our example, the ARN is for the role developer-ec2-mfa that was provided by the IAM administrator. Enter a role session name that will uniquely identify a session when the same role is assumed by different principals.
    aws sts assume-role --role-arn <Role ARN> --role-session-name <Role Name> --serial-number <MFA device ARN> --token-code <token code> --duration-seconds 3600 
    

    Note: The user should only have access to sts:AssumeRole for a specific set of roles. Here we chose the session duration of one hour. You can edit the session duration so the developer can authenticate for the duration of a workday (the default value is 1 hour and can be up to 12 hours). Limit this duration to abide by your organization’s recommended authentication time.

    You should see the following output.

    {
       "AssumedRoleUser": {
          "AssumedRoleId": "ABCD123ABCDEFGHIJKLMN:<role-session-name>",
          "Arn": "arn:aws:sts::<ACCOUNT_ID>:assumed-role/developer-ec2-mfa/<role-session-name>"
       },
       "Credentials": {
          "SecretAccessKey": <aws_secret_access_key>,
          "SessionToken": <aws_session_token>,
          "Expiration": "2020-07-13T19:24:20Z",
          "AccessKeyId": <aws_access_key_id>
       }
    }
    

  4. Edit a new AWS CLI profile named johndoe-developer-role as seen following. Copy the access key and secret key that were retrieved as temporary credentials from the get-session-token command. Then set the additional parameter aws_session_token, which was returned along with the temporary credentials. Edit your CLI with the information for the new role.
    aws configure --profile johndoe-developer-role
    aws configure --profile johndoe-developer-role set aws_session_token <Session Token> 
    

  5. Attempt to make a call to relevant services that are allowed by the newly assumed role. Here’s an example using the Amazon EC2 API to describe the EC2 instances.
    aws --profile johndoe-developer-role ec2 describe-instances
    

The developer now has access to the larger permissions set through the assumed role for the next hour.

Summary

In this post, we introduced the capability to further secure long-term AWS credentials with a YubiKey for MFA, for organizations that are still using long-term credentials. These credentials are stored in the ~/.aws/credentials file. If an unauthorized user was able to retrieve these long-term credentials, they wouldn’t be able to use them, because the user needs to have the physical MFA in order to assume a role with broader permissions. The steps in this blog post can be converted to a script that your developers can use repeatedly to simplify the process.

In general, we recommend that all customers move away from using IAM users and static credentials and instead use IAM roles and temporary credentials wherever possible. An easy way to get started down that road is by using AWS SSO for identity federation.

Optimizing the cost of running AWS Elastic Beanstalk Workloads

Post Syndicated from Mina Gerges original https://aws.amazon.com/blogs/devops/optimizing-the-cost-of-running-aws-elastic-beanstalk-workloads/

AWS Elastic Beanstalk handles provisioning resources, maintenance, health checks, automatic scaling, and other common tasks necessary to keep your application running, which allows you to focus on your application code.

You can now run your applications on Elastic Beanstalk using Amazon Elastic Compute Cloud (Amazon EC2). Spot Instances in both single instance and load balanced environments, For more information see Spot instances support. Spot Instances let you take advantage of unused Amazon EC2 capacity in the AWS Cloud. Spot Instances are available at up to a 90% discount compared to On-Demand prices, which are also available for other deployment services like Amazon Elastic Container Service (Amazon ECS) and Amazon Elastic Kubernetes Service (Amazon EKS). You can use Spot Instances for various stateless, fault-tolerant, or flexible applications, and other test and development workloads.

Customers often ask how to save costs when running their Elastic Beanstalk applications, especially when it comes to test or stage workloads, which don’t need to run all the time. This post walks you through different automation techniques that can reduce your AWS monthly bill significantly.

Converting the environment type

If you have multiple load balanced test environments and want to keep them running after work hours with the lowest possible cost, you can convert the environment type from load balanced to single instance after work hours and back to load balanced in the morning using Amazon Command Line Interface (AWS CLI) commands. For more information see Elastic Beanstalk configuration options.

To convert from load balanced to single instance, enter the following code:

$ aws elasticbeanstalk update-environment --application-name YOUR-APP_NAME --environment-name ENV_NAME --option-settings Namespace=aws:elasticbeanstalk:environment,OptionName=EnvironmentType,Value=SingleInstance

To convert from single instance to load balanced, enter the following code:

$ aws elasticbeanstalk update-environment --application-name YOUR-APP_NAME --environment-name ENV_NAME --option-settings Namespace=aws:elasticbeanstalk:environment,OptionName=EnvironmentType,Value=LoadBalanced

You can then configure cron jobs for these commands at the required times:

# ┌───────────── minute (0 - 59)
# │ ┌───────────── hour (0 - 23)
# │ │ ┌───────────── day of the month (1 - 31)
# │ │ │ ┌───────────── month (1 - 12)
# │ │ │ │ ┌───────────── day of the week (0 - 6) (Sunday to Saturday; 7 is also Sunday on some systems)
# │ │ │ │ │                                  
# * * * * * command to execute

Setting the number of instances

When you have many resources in Elastic Beanstalk environments and want to the optimize the cost during low-traffic times or after work hours while keeping the environment running, a good approach is to set the number of instances to (0 or 1) or any minimal number of instances for all test environments. See the following code:

$ aws elasticbeanstalk update-environment --environment-name ENV-NAME --option-settings Namespace=aws:autoscaling:asg,OptionName=MinSize,Value=0

The preceding code sets the number of instances to 0 while the environment is still running. You can automate this approach for a number of Elastic Beanstalk environments using the following sample bash script:

#!/bin/bash
if [ -z "$1" ] ; then
     echo "$0: <instances to set>"
     exit 1
else
    INSTANCES=$1
fi
 
for environment in environment-1  environment-2 ; do            //please provide here environment names
    aws elasticbeanstalk update-environment --environment-name $environment --option-settings Namespace=aws:autoscaling:asg,OptionName=MinSize,Value=$INSTANCES
done

You can configure a cron job to run this script on a daily basis as per the following example code:

# To set number of instances to 0 (for example at 5:00 PM every day)
$ 0 17 * * * sh test.sh 0    
# To set number of instances to 1 (for example at 8 am)
$ 0 8 * * *  sh test.sh 1 

Stopping your testing environments

When you want to stop all your testing environments overnight, you can terminate Elastic Beanstalk environments after work times and restore them again in the morning. See the following code:

# To terminate environment using AWS CLI (for example at 5:00 PM every day)
$ 0 17 * * * aws elasticbeanstalk terminate-environment --environment-name my-stage-env 
# To restore environment (for example at 8 am)
$ 0 8 * * * eb restore environment-id

For more information, see Terminate an Elastic Beanstalk environment and Rebuilding a terminated environment.

When you terminate Elastic Beanstalk environments, you lose any Amazon Relational Database Service (Amazon RDS) instances that was created previously as a part of the environment. To avoid this, decouple Amazon RDS from your environments. For instructions see, How do I decouple an Amazon RDS instance from an Elastic Beanstalk environment.

Conclusion

In this post, we discussed how different automation techniques can optimize the cost of running Elastic Beanstalk applications, which can result in a significant cost savings. Please feel free to use any approach that suits you or a combination of all of them, depending on your use case.

We appreciate your feedback.

 

DevOps at re:Invent 2019!

Post Syndicated from Matt Dwyer original https://aws.amazon.com/blogs/devops/devops-at-reinvent-2019/

re:Invent 2019 is fast approaching (NEXT WEEK!) and we here at the AWS DevOps blog wanted to take a moment to highlight DevOps focused presentations, share some tips from experienced re:Invent pro’s, and highlight a few sessions that still have availability for pre-registration. We’ve broken down the track into one overarching leadership session and four topic areas: (a) architecture, (b) culture, (c) software delivery/operations, and (d) AWS tools, services, and CLI.

In total there will be 145 DevOps track sessions, stretched over 5 days, and divided into four distinct session types:

  • Sessions (34) are one-hour presentations delivered by AWS experts and customer speakers who share their expertise / use cases
  • Workshops (20) are two-hours and fifteen minutes, hands-on sessions where you work in teams to solve problems using AWS services
  • Chalk Talks (41) are interactive white-boarding sessions with a smaller audience. They typically begin with a 10–15-minute presentation delivered by an AWS expert, followed by 45–50-minutes of Q&A
  • Builders Sessions (50) are one-hour, small group sessions with six customers and one AWS expert, who is there to help, answer questions, and provide guidance
  • Select DevOps focused sessions have been highlighted below. If you want to view and/or register for any session, including Keynotes, builders’ fairs, and demo theater sessions, you can access the event catalog using your re:Invent registration credentials.

Welcome to the real world, where things don’t always go your way. Systems can fail despite being designed to be highly available, scalable, and resilient. These failures, if used correctly, can be a powerful lever for gaining a deep understanding of how a system actually works, as well as a tool for learning how to avoid future failures. In this session, we cover Amazon’s favorite techniques for defining and reviewing metrics—watching the systems before they fail—as well as how to do an effective postmortem that drives both learning and meaningful improvement.

Deploying applications at FINRA using AWS CodeDeploy

Post Syndicated from Nikunj Vaidya original https://aws.amazon.com/blogs/devops/deploying-applications-at-finra-using-aws-codedeploy/

by Geethalaksmi Ramachandran (FINRA – Director, Application Engineering), Avinash Chukka (FINRA – Senior Application Engineer)

At FINRA, a financial regulatory organization that oversees the broker-dealer industry with market intelligence, we have been utilizing the AWS CodeDeploy services to deploy applications on the cloud as well as on on-premises production servers. This blog post provides insight into our operations and experience with CodeDeploy.

Migration overview

Since 2014, we have gone through a systematic effort to migrate over 100 applications from on-premises resources to the AWS Cloud for everything from case management to data ingestion and processing. The applications comprise multiple components or microservices as individually deployable units or a single monolith application with multiple shared components.

Most of the application components, running on Linux and Windows, were entirely redesigned, containerized, and gradually deployed from on-premises to cloud-based Amazon ECS clusters. Fifteen applications were to be deferred for migration or planned for retirement due to other dependencies. Those deferred applications are currently running on on-premises bare-metal servers hosted across 38 Windows servers and 15 Linux servers per environment with a total of 150 Windows servers and 60 Linux servers across all the environments.

The applications were deployed to the on-premises servers earlier using the XL Deploy tool from XebiaLabs. The tool has now been decommissioned and replaced by CodeDeploy to attain more reliability and consistency in deployments across various applications.

Infrastructure and Workflow overview

FINRA’s AWS Cloud infrastructure consists of Amazon EC2 instances, ECS, Amazon EMR clusters, and many resources from other AWS services. We host web applications in ECS clusters, running approximately 200 clusters on each environment and EC2 instances. The infrastructure uses AWS CloudFormation and AWS Java SDK as Infrastructure-as-Code (IaC).

The CI/CD pipeline comprises of:

  • A source stage (per branch) stored in a BitBucket repository
  • A build stage executed on Jenkins build slaves
  • A deploy stage involving deployment from:
    • AWS CloudFormation and SDK to ECS clusters
    • CodeDeploy to EC2 instances
    • CodeDeploy Service to on-premises servers across various development, quality assurance (QA), staging, and production environments.

Jenkins masters running on EC2 instances within an Auto Scaling group orchestrate the CI/CD pipeline. The master spawns the build slaves as ECS tasks to execute a build job. Once the image is built and containerized in the build stage, the build artifact is stored in Artifactory repos for shared common libraries or staged in S3 to be used in deployments. The Jenkins slave invokes the appropriate deployment service – AWS CloudFormation and SDK or CodeDeploy depending on the target server environment, as detailed in the preceding paragraphs. On completion of the deployment, the automated smoke tests are launched.

The following diagram depicts the CD workflow for the on-premises instances:

The Delivery pipeline deploys across various environments such as development, QA, user acceptance testing (UAT), and production. Approval gates control deployments to UAT and production.

CodeDeploy Operations

Our experience of utilizing CodeDeploy services has been “very smooth” since we moved from the XebiaLabs XL Deploy tool three months ago. The main factors that led FINRA to select CodeDeploy for our organization were:

  • Being able to use the same set of deployment tools between on-premises and cloud-based instances
  • Easy portability and reuse of scripts
  • Shared community knowledge rather than isolated expertise

The default deployment parameters were well-suited for our environments and didn’t require altering values or customization. Depending on the application being deployed, deployments can be carried out on cloud-based instances or on-premises instances. Cloud-based instances use AWS CloudFormation templates to trigger CodeDeploy; on-premises instances use AWS CLI-based scripts to trigger CodeDeploy.

The cloud-based deployments in production follow “blue-green” strategy for some of the applications, in which rollback is a critical requirement for minimal disruption. Other applications in cloud follow the “rolling updates” method, where as the on-premises servers in production are upgraded using “in-place” deployment method. The CodeDeploy agents running on on-premises servers are configured with roles to query for required artifacts stored on specific S3 buckets when deploying the package.

The applications’ deployment mappings to the instances are configured based on EC2 Auto Scaling groups in the cloud and based on tags for on-premises resources. Each component is logically mapped to a CodeDeploy deployment group. However, at one point, the maximum number of tags added to the CodeDeploy on-premises instance was restricted to a maximum tag limit of 10, but the instance needed 13 tags corresponding to 13 deployment groups.

We overcame this limitation by adding a common tenth tag on the on-premises instance and also on the remaining deployment groups (10-13) and stored the mapping of instances to deployment groups externally. The deployment script first looks up the mapping and proceeds with the deployment by validating if it matches the target server name, then runs deployments only on the matching target servers and skips deployments on the unmatched servers, as shown in the following diagram.

CodeDeploy offers the following benefits to FINRA:

  • Deployment configurations written as code: CodeDeploy configuration uses CloudFormation templates as Infrastructure-as-Code, which makes it easier to create and maintain.
  • Version controlled deployment code: AWS CloudFormation templates, deployment configuration, and deployment scripts are maintained in the source code repository and version-controlled.
  • Reusability: Most CodeDeploy resource provisioning code is reusable across all the on-premises instances and on different platforms, such as Linux (RHEL) and Windows.
  • Zero maintenance of deployment tool: As a managed service, CodeDeploy does not require maintenance and upgrade.
  • Secrets Management: CodeDeploy integrates with central secrets management systems, and externalizes environment configurations.

Monitoring

FINRA uses the in-house developed DevOps Dashboard to monitor the build and deploy stages, based upon a Grafana UI extracting CI and CD data from Jenkins.

The cloud instances and on-premises servers are configured with agents to stream the real-time logs to a central Splunk Server, where the logs are analyzed and health-monitored. Optionally, the deployment logs are forwarded to the functional owners via email attachments. These logs become critical for the troubleshooting activity in post-mortems of past events. Due to the restrictions on accessing the base instances across various functional teams, the above mechanism enables us to gain visibility into health of the CI/CD infrastructure.

Looking Forward

We plan to migrate the remaining on-premises applications to the cloud after necessary refactoring and retiring of the application dependencies over the next few years.

Our eventual goal is to move towards serverless technologies to eliminate server infrastructure management.

Conclusion

This post reviewed the Infrastructure at FINRA on both AWS Cloud and on-premises, the CI/CD pipeline, and the CodeDeploy workflow integration, as well as examining insights into CodeDeploy use.
