Noticed this alert:
docker system prune freed up 32GB:
razzi@deneb:~$ sudo docker system prune WARNING! This will remove: - all stopped containers - all networks not used by at least one container - all dangling images - all dangling build cache Are you sure you want to continue? [y/N] y ... Total reclaimed space: 33.22GB
Consensus in #wikimedia-sre is to do docker system prune periodically like it happens on CI.
Site note: there are also some user directories taking up a decent amount of space (shown below is >500MB):
