Managing Docker containers with Kubernetes
Running applications in containers is becoming increasingly popular. Containers offer many benefits compared with conventional virtual machines. Docker is a popular container system for Linux that needs only a very minimal base system, so using a conventional, multipurpose operating system with its large collection of miscellaneous components adds a huge overhead if you know all you really want to do is host containers.
The container environment lends itself to portability. In large enterprise environments, IT managers do not want to worry about the type of system a container runs on. The focus is on defining an application with the necessary requirements and deploying it on existing resources. Whether the application actually runs in a container on System A or System B is unimportant.
The need for portability and efficiency has led to development of some special Linux distributions tailored for the container environment. These special distros offer a uniform operating environment, include container management tools, and perhaps most importantly they are optimized for containers – without the feature bloat associated with multipurpose systems.
