Run, stop, resume container

Start a new container and using --name give it an explicit name so it will be easy to find it.

$ docker run --name demo -it busybox

Create file and list it

# echo "hello world" > foobar.txt
# cat foobar.txt

Then exit the container:

# exit

List the containers, and observe that the one we had is stopped.

Restart the same container:

$ docker container start -i demo

Check that the file we created in the previous session is still there.

# cat foobar.txt
