kubectl unfork

A kubectl plugin to find forked helm charts running in a cluster, extract Kustomize compatible patches, and allow you to delete the fork and return to the upstream Chart, while preserving your patches.

Usage:

curl https://unfork.io/install | bash
kubectl unfork

This plugin will:

• Connect to your Kubernetes cluster and search for a Helm Tiller pod.
• Connect to your Tiller using the Helm GRPC API and query to receive a list of all installed Helm Charts.
• Meanwhile, Unfork will download a list of all known Helm Charts from Monocular.
• Comparing your Helm charts with the Monocular index, Unfork will attempt to determine which upstream your fork is from.
• Once you've confirmed the best upstream, Unfork will convert your custom changes into Kustomize patches and resources.
• You can now update the Helm chart to the latest version, and re-apply your patches.

Note: Unfork does not make any changes to the applications running in your cluster. Unfork only needs access to your cluster in order to port-forward and gain access to Tiller.
