Object Propagation Controller

This controller source objects into the target namespaces.

Each set of source objects is specified using:

• apiVersion - required
• kind - required
• namespace - required
• label selector - may be empty ("")

The target namespace is specified by a label selector, which may be empty ("").

target.detectAndReplaceSourceNSRef can be used to indicate that references to the source namespace should be replaced with the target namespace.

The controller reads configuration provided via --input CLI parameter (default: /dev/stdin). Example input:

- source:
    apiVersion: v1
    kind: ConfigMap
    namespace: tanzu-system
    labelSelector: 'run.tanzu.vmware.com/propagated'
  target:
    namespaceLabelSelector: '!cluster.x-k8s.io/provider'
    detectAndReplaceSourceNSRef: true
- source:
    apiVersion: v1
    kind: Secret
    namespace: tanzu-system
    labelSelector: 'run.tanzu.vmware.com/propagated'
  target:
    namespaceLabelSelector: '!cluster.x-k8s.io/provider'
