Docker

Build container

$ docker-compose build
Start services

$ docker-compose up
List images

$ docker images
Remove dangling images:

When you run a docker-compose build, it creates a new image, but it doesn't remove the old one, so you can have a lot of images with the same name but different id. Then, you can remove all of them with the following command:
$ docker rmi $(docker images -f dangling=true -q) -f
Deep Cleaning - Free space on your disk

Warning: This will remove all containers, images, volumes and networks not used by at least one container. Its recommended to run this command before docker-compose up to avoid problems.
$ docker system prune -a --volumes
