Cheat Sheet

Basics

• docker command line structure

docker command sub-command (options)

• use --help after any of the command below to get help on syntax and available subcommands or options

Old vs new commands

• Lot of commands are moving under specific resource commands
  • E.g. docker ls is now available in docker container or docker image, etc.

Info

docker version                  # shows information about client and server
docker info                     # show config values

Containers

Manage Containers

docker container ls             # list active containers
docker container ls -a          # list all containers, including those that are inactive
docker rm <id> <id> <id>        # removes inactive containers
docker rm -f <id> <id>          # removes any containers

docker update                   # update configuration of one or more containers

Various information

docker container top            # process list in one container
docker container inspect        # returns JSON metadata about the container
docker container stats          # performance stats for all containers
docker container port           # show which ports are open for a container

Shell and Execute

docker container run -it        # start new container interactively
docker container start -ai      # start existing container interactively
docker container exec -it       # run additional command in existing container

Format
