Templating Kubernetes Secret Resources

Rendering Secret objects without leaking values.

Charts Can Render Secrets

Sometimes your chart must produce a Kubernetes Secret object itself. Done carefully, you can template one without leaking the value.

A Kubernetes Secret is just a manifest with a data section. Each value under data must be Base64-encoded text.

apiVersion: v1
kind: Secret
metadata:
  name: db-credentials
