I have a controller which Reconciles MyKind Custom Resource in 'foo' namespace. Within the reconcile loop, it creates a deployment MyDeployment in 'bar' namespace. I am wondering how can I setup a watch on the MyDeployment created in 'bar' namespace which is different than namespace ('foo') where the custom resource live.
I tried setting up my manager with the following, but it doesnt seem to work since the deployment I am trying to watch are in different namespace hence the controller is not able to receive any events for the CRUD operation on the deployment.
return controllerruntime.NewControllerManagedBy(mgr).
For(&v1alpha1.MyKind{}).
Owns(&appsv1.Deployment{}).
Complete(r)
}
Is there any custom watch that I can configure my controller with in order to receive events for the deployment in a different namespace.
Note: I tried handler.EnqueueRequestsFromMapFunc, IIUC it also reconciles for Kinds in the same namespace.
You can specify namespaces in the manager options by passing in a ctrl.Options{}
object, while creating it.
namespace := "namespace1,namespace2"
options := ctrl.Options{
.
.
.
Namespace: cache.MultiNamespacedCacheBuilder(strings.Split(namespace, ","))
}
mgr, err := ctrl.NewManager(ctrl.GetConfigOrDie(), options)
