Build

Build an image from the Dockerfile in the current directory and tag the image

docker build -t myimage -f Dockerfile .

List all images that are locally stored with the Docker Engine

docker ps -a

Delete an image from the local image store

docker image rm CONTAINER_NAME

You may want to remove all orphaned images, you can do this with dandling field

docker rmi $(docker images -f dangling=true -q)

Run

Run a container from the myimage

docker run -it --rm myimage

Stop a running container

docker stop myimage

Kill a running container

docker container kill web

List the running containers (add –all to include stopped containers)

docker container ls

Delete all running and stopped container

 docker container rm -f $(docker ps -aq)

Print the last 100 lines of a container’s logs

docker container logs --tail 100 web

Containers

Your basic isolated Docker process. Containers are to Virtual Machines as threads are to processes. Or you can think of them as chroots on steroids.

Lifecycle

• docker create creates a container but does not start it.
• docker rename allows the container to be renamed.
• docker run creates and starts a container in one operation.
• docker rm deletes a container.
• docker update updates a container’s resource limits.

Normally if you run a container without options it will start and stop immediately, if you won’t keep it running you can use the command, docker run -td container_id this will use the option -t that will allocate a pseudo-TTY session and -d that will detach automatically the container (run container in background and print container ID).

If you want a transient container, docker run --rm will remove the container after it stops.

If you want to map a directory on the host to a docker container, docker run -v $HOSTDIR:$DOCKERDIR. Also, see Volumes.

If you want to remove also the volumes associated with the container, the deletion of the container must include the -v switch like in docker rm -v.

There’s also a logging driver available for individual containers in docker 1.10. To run docker with a custom log driver (i.e., to syslog), use docker run --log-driver=syslog.

Another useful option is docker run --name yourname docker_image because when you specify the --name inside the run command, this will allow you to start and stop a container by calling it with the name you specified when you created it.

Starting and Stopping

• docker start starts a container so it is running.
• docker stop stops a running container.
• docker restart stops and starts a container.
• docker pause pauses a running container, “freezing” it in place.
• docker unpause will unpause a running container.
• docker wait blocks until running container stops.
• docker kill sends a SIGKILL to a running container.
• docker attach will connect to a running container.

If you want to detach from a running container, use Ctrl + p, Ctrl + q. If you want to integrate a container with a host process manager, start the daemon with -r=false then use docker start -a.

If you want to expose container ports through the host, see the exposing ports section.
