Image Cleanup

This repository manages a simple maintenance utility used to keep the server's Docker environment clean. It prevents disk space exhaustion by removing unused data.

🛠️ Functionality

The service executes a deep cleanup of the Docker system using the following command:

docker system prune -af --volumes

This command removes:

• All stopped containers.
• All networks not used by at least one container.
• All images without at least one container associated with them.
• All build cache.
• All unused volumes.

📅 Automation Schedule

The cleanup is managed by Woodpecker CI and is triggered in two ways:

• Weekly Cron: A scheduled task that runs once a week to ensure the host doesn't accumulate "cruft" over time.
• Manual Push: Any push to the main branch will trigger an immediate cleanup, allowing for on-demand maintenance.

📂 Repository Structure

.woodpecker.yaml: Defines the cleanup logic and the triggers (cron and push events).

⚠️ Important Note

Since this service uses the -a (all) and --volumes flags, it is very thorough. Ensure that any data you wish to persist is explicitly mapped to a persistent volume or handled by a running container, as unreferenced volumes will be purged.
