Hi
To do maintenance on my Discourse instances, I tried to use

./launcher cleanup app

command, but it seems to be blocked : I launched the command minutes ago, and nothing happens (and no space is freed on the disk).

(I reproduce the problem on multiple up-to-date instances)

Can the command be very long to execute ?

Yes, I can confirm this. Whatever

./launcher cleanup

is trying to do, it’s just hanging now @saj

root@endoffice-a:/var/discourse# ./launcher cleanup app
^C

It looks like we replaced the old spotify/docker-gc with the built in Docker command

$docker_path system prune -a

That seems to work fine for me though, when entered manually:

root@endoffice-a:/var/discourse# docker system prune -a
WARNING! This will remove:
  - all stopped containers
  - all networks not used by at least one container
  - all images without at least one container associated to them
  - all build cache

Are you sure you want to continue? [y/N] y

Hopefully it’s some minor thing regarding BASH code, I dunno.
