PushSecret

The PushSecret is namespaced and it describes what data should be pushed to the secret provider.

• tells the operator what secrets should be pushed by using spec.selector.
• you can specify what secret keys should be pushed by using spec.data.
• you can also template the resulting property values using templating.

    data:
      best-pokemon: "{{ .best-pokemon | toString | upper }} is the really best!"
    # Uses an existing template from configmap
    # Secret is fetched, merged and templated within the referenced configMap data
    # It does not update the configmap, it creates a secret with: data["alertmanager.yml"] = ...result...
    templateFrom:
      - configMap:
          name: application-config-tmpl
          items:
            - key: config.yml
  data:
    - conversionStrategy: None # Also supports the ReverseUnicode strategy
      match:
        secretKey: best-pokemon # Source Kubernetes secret key to be pushed
        remoteRef:
          remoteKey: my-first-parameter # Remote reference (where the secret is going to be pushed)

Templating

When the controller reconciles the PushSecret it will use the spec.template as a blueprint to construct a new property. You can use golang templates to define the blueprint and use template functions to transform the defined properties. You can also pull in ConfigMaps that contain golang-template data using templateFrom. See advanced templating for details.
