Filter docker containers by name and stop them

Question

I'm trying to stop all the containers starting with the name app_

I though this would work: docker stop $(docker ps -f name="app_*"), but it shows:

unknown shorthand flag: 'f' in -f
See 'docker stop --help'.

Is there a way to do this?

Answer 1

You must put the complete filter expression into parantheses:

docker ps -f "name=app_*"

The search is fuzzy by default, so e.g. name=app will also return my-app. You can use a regex to indicate that the match should be at the start:

docker ps -f "name=^app_"

You should further add the quiet flag q so that the command only returns ids to make it work with docker stop:

docker stop $(docker ps -qf "name=^app_")
