kubernetes-manifest-exporter

Scripts to export all kubernetes manifests from your cluster.

This comes in handy when you want to migrate a cluster, or use a gitbased config management tool such as kpt-config-sync or Anthos Config Management

Reqirements

Ensure that you have kubectl and are on the correct context for the cluster you want to export

You will need kubectl neat, this cleans the manifest files from excess metadata.

kubectl krew install neat

Visit the kubectl-neat repo page for more information on kubectl-neat.
