docker-compose コンテナの停止、ネットワーク・名前付きボリューム・コンテナイメージ・未定義サービスコンテナを削除

コンテナの停止、ネットワーク・名前付きボリューム・コンテナイメージ・未定義サービスコンテナをまとめてスマートに削除できないかと3ヶ月くらい考えていたら良いオプションを発見しました。

神のコマンド

$ docker-compose down --volumes --rmi all --remove-orphans
Stopping docker-sample_web_1 ... done
Stopping docker-sample_app_1 ... done
Stopping docker-sample_db_1  ... done
Removing docker-sample_web_1 ... done
Removing docker-sample_app_1 ... done
Removing docker-sample_db_1  ... done
Removing network docker-sample_default
Removing volume docker-sample_db-store
Removing image docker-sample_app
Removing image nginx:1.17.0-alpine
Removing image mysql:8.0.16

docker volume prune や docker volume ls で探して docker volume rm で指定してがんばって削除しなくてよくなったので嬉しいです😊

付録

$ docker-compose down -h
Stops containers and removes containers, networks, volumes, and images
created by `up`.

By default, the only things removed are:

- Containers for services defined in the Compose file
- Networks defined in the `networks` section of the Compose file
- The default network, if one is used

Networks and volumes defined as `external` are never removed.

Usage: down [options]

Options:
    --rmi type              Remove images. Type must be one of:
                              'all': Remove all images used by any service.
                              'local': Remove only images that don't have a
                              custom tag set by the `image` field.
    -v, --volumes           Remove named volumes declared in the `volumes`
                            section of the Compose file and anonymous volumes
                            attached to containers.
    --remove-orphans        Remove containers for services not defined in the
                            Compose file
    -t, --timeout TIMEOUT   Specify a shutdown timeout in seconds.
                            (default: 10)
