How can I prevent Docker Compose from copying saved volumes into a new container?

How can I prevent docker-compose up from copying saved volumes from the previous session into a container? In effect, I want Docker Compose to behave like docker run which discards the contents of private volumes when its container exits.

docker docker-compose

    It seems that no option exists to prevent docker-compose up from using volumes from a previous session. The best alternative I could think of is to stop the containers and then remove the containers and their private volumes:

    docker-compose stop
docker-compose rm -fv

    Note that unlike docker-compose down --volumes, this preserves named volumes.

  2. Try using docker-compose up --force-recreate. See https://docs.docker.com/compose/reference/up/ for more details.

    I think that problem is that docker-compose up is re-using existing containers, so existing volumes are re-used as well (there is no actual copying of the data).
