Docker hint

Most popular docker commands in one hint here.

Post in the comments if you have what to add to this list!

Build an image from Dockerfile when you are in a folder with it and start the container instantly (and run bash inside of it):

docker run --rm -it $(docker build -q .) bash

Stop all containers on the host in one command:

docker kill $(docker ps -q)

Attach to the existing running container and run bash there:

docker exec -it stack-master_nginx_1 bash

To get the container name, run:

docker ps

Example output:

CONTAINER ID   IMAGE               COMMAND                  CREATED             STATUS             PORTS  NAMES
3dc80e13f898   stack-master_nginx  "/docker-entrypoint.…"   About an hour ago   Up About an hour           stack-master_nginx_1

To restart the container:

docker restart master_nginx_1

Enable docker build kit which is the simplest way to build images faster:

export DOCKER_BUILDKIT=1

Note: this works only for Docker 18.09+

To get daemon version:

docker info | grep 'Server Version'

Universal space cleaner which removes:

docker system prune -a -f

Remove only dangling images silently:

docker 2>/dev/null 1>&2 rmi $(docker images -f "dangling=true" -q) || true
