示例1: updateReplicaCount

// updateReplicaCount attempts to update the Status.Replicas of the given ReplicaSet, with a single GET/PUT retry.
func updateReplicaCount(rsClient client.ReplicaSetInterface, rs extensions.ReplicaSet, numReplicas, numFullyLabeledReplicas int) (updateErr error) {
	// This is the steady state. It happens when the ReplicaSet doesn't have any expectations, since
	// we do a periodic relist every 30s. If the generations differ but the replicas are
	// the same, a caller might've resized to the same replica count.
	if int(rs.Status.Replicas) == numReplicas &&
		int(rs.Status.FullyLabeledReplicas) == numFullyLabeledReplicas &&
		rs.Generation == rs.Status.ObservedGeneration {
		return nil
	}
	// Save the generation number we acted on, otherwise we might wrongfully indicate
	// that we've seen a spec update when we retry.
	// TODO: This can clobber an update if we allow multiple agents to write to the
	// same status.
	generation := rs.Generation

	var getErr error
	for i, rs := 0, &rs; ; i++ {
		glog.V(4).Infof(fmt.Sprintf("Updating replica count for ReplicaSet: %s/%s, ", rs.Namespace, rs.Name) +
			fmt.Sprintf("replicas %d->%d (need %d), ", rs.Status.Replicas, numReplicas, rs.Spec.Replicas) +
			fmt.Sprintf("fullyLabeledReplicas %d->%d, ", rs.Status.FullyLabeledReplicas, numFullyLabeledReplicas) +
			fmt.Sprintf("sequence No: %v->%v", rs.Status.ObservedGeneration, generation))

		rs.Status = extensions.ReplicaSetStatus{Replicas: int32(numReplicas), FullyLabeledReplicas: int32(numFullyLabeledReplicas), ObservedGeneration: generation}
		_, updateErr = rsClient.UpdateStatus(rs)
		if updateErr == nil || i >= statusUpdateRetries {
			return updateErr
		}
		// Update the ReplicaSet with the latest resource version for the next poll
		if rs, getErr = rsClient.Get(rs.Name); getErr != nil {
			// If the GET fails we can't trust status.Replicas anymore. This error
			// is bound to be more interesting than the update failure.

		}

示例2: updateReplicaSetStatus

// updateReplicaSetStatus attempts to update the Status.Replicas of the given ReplicaSet, with a single GET/PUT retry.
func updateReplicaSetStatus(c unversionedextensions.ReplicaSetInterface, rs extensions.ReplicaSet, newStatus extensions.ReplicaSetStatus) (updateErr error) {
	// This is the steady state. It happens when the ReplicaSet doesn't have any expectations, since
	// we do a periodic relist every 30s. If the generations differ but the replicas are
	// the same, a caller might've resized to the same replica count.
	if rs.Status.Replicas == newStatus.Replicas &&
		rs.Status.FullyLabeledReplicas == newStatus.FullyLabeledReplicas &&
		rs.Status.ReadyReplicas == newStatus.ReadyReplicas &&
		rs.Status.AvailableReplicas == newStatus.AvailableReplicas &&
		rs.Generation == rs.Status.ObservedGeneration &&
		reflect.DeepEqual(rs.Status.Conditions, newStatus.Conditions) {
		return nil
	}

	// deep copy to avoid mutation now.
	// TODO this method need some work.  Retry on conflict probably, though I suspect this is stomping status to something it probably shouldn't
	copyObj, err := api.Scheme.DeepCopy(rs)
	if err != nil {
		return err
	}
	rs = copyObj.(extensions.ReplicaSet)

	// Save the generation number we acted on, otherwise we might wrongfully indicate
	// that we've seen a spec update when we retry.
	// TODO: This can clobber an update if we allow multiple agents to write to the
	// same status.
	newStatus.ObservedGeneration = rs.Generation

	var getErr error
	for i, rs := 0, &rs; ; i++ {
