Mon aide-mémoire Docker – Docker cheat sheet

Docker

docker ps	List running containers
docker images	List docker images
docker exec -it <container_id> bash	Launch a shell in a running container
docker rm <container_id>	Remove container
docker rmi <image_id>	Remove image
docker stop $(docker ps -a -q)	Stop all containers
docker rm $(docker ps -a -q)	Remove all containers

Build a docker image named « web » using a Dockerfile found in current directory (« . »)

docker build -t web .

Same as above but disable cache to force a complete rebuild

docker build --no-cache=true -t web .

Docker Machine

Create dev machine

docker-machine -D create -d virtualbox dev

Create production machine (on DigitalOcean)

docker-machine -D create -d digitalocean --digitalocean-region=fra1 --digitalocean-access-token=<token> production

Set shell environment to use dev machine

eval "$(docker-machine env dev)"

You can now run any docker or docker-compose commands on your machine

Unset shell env variables

eval "$(docker-machine env -u)"
