Types

type ManagedCAObserver

type ManagedCAObserver struct {

	// Client is a client that allows access to the management cluster
	Client kubeclient.Interface

	// TargetCMLister is a lister for configmaps in the target cluster
	TargetCMLister corev1listers.ConfigMapLister

	// Namespace is the namespace where the control plane of the cluster
	// lives on the management server
	Namespace string

	// InitialCA is the initial CA for the controller manager
	InitialCA string

	// Log is the logger for this controller
	Log logr.Logger
}

ManagedCAObserver watches 2 CA configmaps in the target cluster: - openshift-managed-config/router-ca - openshift-managed-config/service-ca It populates a configmap on the management cluster with their content. A separate controller uses that content to adjust the configmap for the Kube controller manager CA.

func (*ManagedCAObserver) Reconcile

func (r *ManagedCAObserver) Reconcile(req ctrl.Request) (ctrl.Result, error)

Reconcile periodically watches for changes in the CA configmaps and updates the kube-controller-manager-ca configmap in the management cluster with their content.
