Podman Storage & Container Cache (~/.local/share/containers/storage)

Bottom Line: It is 100% safe to clear unused Podman storage. Running podman system prune --all will remove dangling container images, stopped containers, and build caches without harming your system.

What is the Podman Storage Folder?

Located at ~/.local/share/containers/storage on Linux (or inside the Podman machine VM on macOS/Windows), this directory is used by Podman (the daemonless alternative to Docker).

Unlike Docker (which runs a system daemon storing files in /var/lib/docker), Podman runs rootless in user space. Every container image pulled, intermediate build layer, stopped container, and overlay filesystem block is stored inside containers/storage.

Over months of building container images, unused container layers accumulate, consuming 10 GB to 60 GB+ of drive space.

Can You Delete Podman Storage?

✅ Yes, it is safe to clear.

• No code risk: Your source code, Dockerfile manifests, and project repositories are completely safe.
• Auto-rebuilt: Re-running podman build or podman run will automatically download required base images from registries like Quay or Docker Hub.

How to Safely Clean Up Podman Storage

Method 1: Using the Podman CLI (Recommended)

1. Open your terminal.
2. Remove stopped containers, unused networks, and dangling build caches:

   podman system prune

3. To purge all unused container images as well:

   podman system prune --all --volumes
