Running Containers
Use a simple throwaway container
In this section you will learn how to start and stop containers.
$ docker run -it --rm busybox /bin/sh - docker run – Start a docker container.
- -it – Interactive, pass stdin (-i) as a tty, pass signals (-t).
- –rm – Remove the container once it is stopped.
- busybox – A minimal docker image
- /bin/sh – The command to run, start a shell.
Use a simple “persistent” container
$ docker run -it busybox /bin/sh Same as before, but no –rm to remove the container once you exit.
Run some commands, create a couple of files, then exit exit-command or Ctrl-D
# List all containers, including stopped
$ docker ps --all
# List all running containers
$ docker ps
# List all container IDs (-q quiet)
$ docker ps --all -q
# List latest (-l) container, including stopped
$ docker ps -l
# List ID of latest container $ docker ps -l -q
# Stop the last container
$ docker stop $(docker ps -l -q)
# Start and attach to the stopped container
$ docker start -ia $(docker ps -l -q)
# Exit the container, exit or Ctrl-D
# List the container and remember its name.
$ docker ps -a
# List the logs of the container by name
$ docker logs name-of-container
# Remove the container
$ docker rm $(docker ps -l -q) # Or use the nameCode language: PHP (php)
