Safe Image Prune Execution Report
Scope
Command used:
docker image prune -a -f
Cleanup target: unused images only. Running containers and volumes remain untouched.
Before vs After Pattern
Track these metrics each run:
- image count and total image size
- reclaimable image bytes
- host root filesystem used and available space
Safety Notes
- execute in maintenance windows
- capture
docker system df -vbefore and after - verify all required image tags still exist for rollback and redeploy
