apptainer(1)

NAME 💖

apptainer-cache-clean — clean your local Apptainer cache. okay bestie, yes, this is the apptainer(1) manual page for it, and it’s giving “fresh cache, fresh me” energy ✨

SYNOPSIS ✨

apptainer cache clean [clean options...]

DESCRIPTION 🌸

This cleans your local cache, which lives at $HOME/.apptainer/cache if APPTAINER_CACHEDIR is not set. By default the entire cache is cleaned — yes, all of it, no crumbs left. Wanna override that behavior? Use the --days and --type flags, bestie 💅

Root alert 🚨 if you use Apptainer as root, the cache is stored in /root/.apptainer/.cache. To clean that cache, you need to run cache clean as root, or with sudo — periodt.

OPTIONS 💅

• -D, --days=0 — remove all cache entries older than specified number of days. that’s the whole gig 🎀
• -n, --dry-run[=false] — operate in dry run mode and do not actually clean the cache. look but don’t touch vibes, fr fr ✨
• -f, --force[=false] — suppress any prompts and clean the cache. no questions, just cleaning 💅
• -h, --help[=false] — help for clean. yep, the little helper 🫶
• -T, --type=[all] — a list of cache types to clean (possible values: library, oci, shub, blob, net, oras, all). pick your fighters 🎀

EXAMPLE 🎀

All group commands have their own help output — fr fr:

$ apptainer help cache clean --days 30
$ apptainer help cache clean --type=library,oci
$ apptainer cache clean --help
