Disk & Cleanup

• In the dashboard's disk cleanup settings, choose how many recent deployed versions per app to retain.

• CapRover's DiskCleanupManager scans Docker images; for each app it protects the deployed version and the preceding mostRecentLimit versions when their tags match saved deployment image names.

• It then attempts to remove images outside that set.

• To run cleanup on a schedule, enter a valid cron expression and timezone.

• The schedule uses the configured timezone.

• Clearing the expression disables the scheduled job; the saved retention count resets to 1.

• A negative retention value is rejected.

• Confirm that older images are available from a registry or rebuild before removing them; cleanup can affect rollback.

• This is image cleanup, not database, volume, log, or registry cleanup.

• Inspect docker system df and docker volume ls before any manual cleanup.

• Avoid broad volume pruning: an unused volume can still contain important data for a stopped or broken app.
