Method Lock

runtime/controller.go:816–826

Lock locks the controller's catalog and delays scheduling of new reconciliations until the lock is released. It can only be called from within a reconciler invocation. While the lock is held, resources can only be edited by a caller using the ctx passed to Lock.

(ctx context.Context)

// It can only be called from within a reconciler invocation.
// While the lock is held, resources can only be edited by a caller using the ctx passed to Lock.
func (c *Controller) Lock(ctx context.Context) {
	inv := invocationFromContext(ctx)
	if inv == nil {
		panic("Lock called outside of a reconciler invocation")
	}
	if inv.holdsLock {
		panic("Lock called by invocation that already holds the lock")
	}
	inv.holdsLock = true
	c.mu.Lock()
}

// Unlock releases the lock acquired by Lock.
func (c *Controller) Unlock(ctx context.Context) {
