Kubernetes Helm Chart Cache Folder (~/.cache/helm)

Bottom Line: It is 100% safe to delete the Helm cache folder. Deleting ~/.cache/helm will NOT delete your deployed Kubernetes cluster releases or custom Helm value YAML files.

What is the Helm Cache Folder?

Located at ~/.cache/helm on Linux/macOS (and %LocalAppData%\helm\cache on Windows), this folder is created by Helm (the package manager for Kubernetes).

Helm caches:

• Repository Indexes (repository/): Cached YAML index files from chart repositories (e.g. Bitnami, Artifact Hub).
• Downloaded Charts (archive/): Compressed .tgz Helm chart tarballs fetched during helm install or helm dependency build.

Over months of managing Kubernetes infrastructure, obsolete Helm chart archives accumulate, taking up 1 GB to 6 GB+.

Can You Delete Helm Cache?

✅ Yes, it is completely safe to delete.

• No live cluster risk: Active Kubernetes workloads running in your cluster stay 100% safe.
• Auto-fetched: Running helm repo update or helm install will automatically re-download required chart repositories.
