Docker has transformed the way
many people develop and deploy software. It wasn’t the first
implementation of containers on Linux, but Docker’s ideas about how
containers should be structured and managed were different from its
predecessors. Those ideas matured into industry standards, and an
ecosystem of software has grown around them. Docker continues to be a
major player in the ecosystem, but it is no longer the only whale in the
sea — Red Hat has also done a lot of work on
container tools, and alternative implementations are
now available for many of Docker’s offerings.
