Do you routinely do 'docker system prune' or anything else to maintain your Discourse instances?

I’m having a tidy up and just reclaimed 28GB by doing this.

Ensure all forums are running (so NOT stopped) then:

docker system prune

And confirm with Y.

Does anybody else do it? Is it (and/or anything else) routinely recommended by the Discourse team in order to maintain our Discourse instances?

I let the Docker updater purge old containers when it runs low on space, but that only happens when I’m updating Docker, so its rare. Sounds like you have multiple Discourse instances going, I can’t speak to that.

./launcher cleanup is more recommended, and covered in many many topics here on meta…

Thanks, does it remove just containers?

cleanup: Remove all containers that have stopped for > 24 hours

docker system prune does:

        - all stopped containers
        - all networks not used by at least one container
        - all dangling images
        - all build cache

If so would it be worth doing cleanup first then the docker prune?

A lot of the HD space reclaimed was via removed images:
