Cleanup option does not seem to work. #2103
Description
Describe the bug
I've been using watchtower for the past year or so and I really like how seamless it runs, but I've never been able to get the WATCHTOWER_CLEANUP option to work.
My docker_compose.yml is as follows.
watchtower:
image: containrrr/watchtower
container_name: watchtower
environment:
- WATCHTOWER_HTTP_API_METRICS=true
- WATCHTOWER_HTTP_API_TOKEN=censored
- WATCHTOWER_NOTIFICATION_REPORT=true
- WATCHTOWER_NOTIFICATION_URL=generic://notifiarr.com/api/v1/notification/watchtower>
- WATCHTOWER_CLEANUP=true
volumes:
- /var/run/docker.sock:/var/run/docker.sock
ports: - 800:8080
restart: unless-stopped
I removed and restarted the container, so I don't have the logs at the moment, but once it runs an update I'll add them to this issue. I did not see any mention of the cleanup in the logs, though.
Steps to reproduce
- Pull and run Watchtower using my docker_compose.yml file.
- Wait for a container to update.
- Get frustrated when your SSD fills up in three days.
Expected behavior
Cleanup option should be removing old container images upon completing updates.
