# To start the docker daemon:
docker -d

# To start a container with an interactive shell:
docker run -ti <image-name> /bin/bash

# To "shell" into a running container (docker-1.3+):
docker exec -ti <container-name> bash

# To inspect a running container:
docker inspect <container-name> (or <container-id>)

# To get the process ID for a container:
docker inspect --format {{.State.Pid}} <container-name-or-id>

# To list (and pretty-print) the current mounted volumes for a container:
docker inspect --format='{{json .Volumes}}' <container-id> | python -mjson.tool

# To copy files/folders between a container and your host:
docker cp foo.txt mycontainer:/foo.txt

# To list currently running containers:
docker ps

# To list all containers:
docker ps -a

# To remove all stopped containers:
docker rm $(docker ps -qa)

# To list all images:
docker images

# To remove all untagged images:
docker rmi $(docker images | grep "^<none>" | awk "{print $3}")

## example, pass device.
docker run -it \
    --net host \ # may as well YOLO
    --cpuset-cpus 0 \ # control the cpu
    --memory 512mb \ # max memory it can use
    -v /tmp/.X11-unix:/tmp/.X11-unix \ # mount the X11 socket
    -e DISPLAY=unix$DISPLAY \ # pass the display
    -v $HOME/Downloads:/root/Downloads \ # optional, but nice
    -v $HOME/.config/google-chrome/:/data \ # if you want to save state
    --device /dev/snd \ # so we have sound
    --name chrome \
    jess/chrome
