IntroductionDocker[1] is a containerization tool that helps developers create and manage portable, consistent Linux containers.
When developing or deploying containers you’ll often need to look inside a running container to inspect its current state or debug a problem. To this end, Docker provides the docker exec command to run programs in containers that are already running.
