containers

 run is the command used to start new containers. In its simplest form, it accepts an image and a command as arguments. The image is used to create the container and the command is the application you want the container to run. This example will start an Ubuntu container in the foreground, and tell it to run the Bash shell: docker container run -it ubuntu /bin/bash

will detach your shell from the terminal of a container and leave the container running (UP) in the background

lists all containers in the running (UP) state. If you add the -a flag you will also see containers in the stopped (Exited) state. • docker container exec lets you run a new process inside of a running container. It’s useful for attaching the shell of your Docker host to a terminal inside of a running container. This command will start a new Bash shell inside of a running container and connect to it: docker container exec -it <container-name or container-id> bash

will stop a running container and put it in the Exited (0) state. It does this by issuing a SIGTERM to the process with PID 1 inside of thecontainer.Iftheprocesshasnotcleanedupandstoppedwithin10seconds, a SIGKILL will be issued to forcibly stop the container. docker container stop accepts container IDs and container names as arguments

will restart a stopped (Exited) container. You can give docker container start the name or ID of a container

will delete a stopped container. You can specify containers by name or ID

will show you detailed configuration and run time information about a container. It accepts container names and container IDs as its main argument
