Docker Commands

Docker useful commands -   

• docker –version

• docker ps  -- This command is used to list the running containers.
• docker ps -a -- This command is used to show all the running and exited containers
• docker exec -it <container id> bash  -- This command is used to access the running container
• docker stop <container id> -  This command stops a running container
• docker kill <container id> - This command kills the container by stopping its execution immediately. The difference between ‘docker kill’ and ‘docker stop’ is that ‘docker stop’ gives the container time to shutdown gracefully, in situations when it is taking too much time for getting the container to stop, one can opt to kill it
