What are some common docker commands? (Linda)

I never actually really bothered to learn docker before (hah) so picked up a couple of commands that felt useful:

• list all the containers running

$ docker ps

• How to pull a docker postgres image (specifically postgres 11.1)

$ docker pull postgres:11.1

• See all the images you have

$ docker images

• The place your postgres image probably exists

$HOME/docker/volumes/postgres

• How to prune your docker system of all unused volumes (I think?)

$ docker system prune --all --volumes
