subcontroller

Documentation

Overview

Package subcontroller is a part of the VitessBackupStorage controller that runs as its own Pod, separate from the operator's main controller-manager.

You can think of this like a part of the VitessBackupStorage controller that's forked off into a new Pod for each VitessBackupStorage object, so each Pod can independently mount things like Secrets or NFS volumes that are specific to a given VitessBackupStorage object.

See cmd/manager/main.go for details.

Functions

func Add

func Add(mgr manager.Manager) error

Add creates a new subcontroller and adds it to the Manager.

Note that this Add function is intentionally NOT registered in the top-level pkg/controller package, because this controller does not run in the root process. See cmd/manager/main.go for details.

Types

type ReconcileVitessBackupStorage

type ReconcileVitessBackupStorage struct {
	// contains filtered or unexported fields
}

ReconcileVitessBackupStorage reconciles a VitessBackupStorage object

func (*ReconcileVitessBackupStorage) Reconcile

func (r *ReconcileVitessBackupStorage) Reconcile(cctx context.Context, request reconcile.Request) (reconcile.Result, error)

Reconcile reads that state of the cluster for a VitessBackupStorage object and makes changes based on the state read and what is in the VitessBackupStorage.Spec Note: The Controller will requeue the Request to be processed again if the returned error is non-nil or Result.Requeue is true, otherwise upon completion it will remove the work from the queue.
