Remove a named volume with docker-compose?

Question

If I have a docker-compose file like:

version: "3" services:   postgres:     image: postgres:9.4     volumes:       - db-data:/var/lib/db volumes:   db-data: 

... then doing docker-compose up creates a named volume for db-data. Is there a way to remove this volume via docker-compose? If it were an anonymous volume, then docker-compose rm -v postgres would do the trick. But as it stands, I don't know how to remove the db-data volume without reverting to docker commands. It feels like this should be possible from within the docker-compose CLI. Am I missing something?

Answer 1

docker-compose down -v 

removes all volumes attached. See the docs

Answer 2

There's no way to target the removal of a specific named volume with the docker-compose cli. Instead this can be achieved using the docker cli. See the docs.

Use docker volume ls to find the name of specific volume.

Remove the volume using docker volume rm VOLUME_NAME. You will need to have stopped and removed containers using the volume.

An example approach:

# Stop and remove container's using the target volume docker-compose stop NAME_OF_CONTAINER  # We need the force flag, "-f", as the container is still bound to the volume docker-compose rm -f NAME_OF_CONTAINER  # Next find your volume name in the following list docker volume ls  # Finally remove the volume docker volume rm VOLUME_NAME
