type RollingUpdater added in v0.9.0

func NewRollingUpdater added in v0.9.0 

func NewRollingUpdater(namespace string, rcClient coreclient.ReplicationControllersGetter, podClient coreclient.PodsGetter, sc scaleclient.ScalesGetter) *RollingUpdater

NewRollingUpdater creates a RollingUpdater from a client.

func (*RollingUpdater) Update added in v0.9.0 

func (r *RollingUpdater) Update(config *RollingUpdaterConfig) error

Update all pods for a ReplicationController (oldRc) by creating a new controller (newRc) with 0 replicas, and synchronously scaling oldRc and newRc until oldRc has 0 replicas and newRc has the original # of desired replicas. Cleanup occurs based on a RollingUpdaterCleanupPolicy.

Each interval, the updater will attempt to make progress however it can without violating any availability constraints defined by the config. This means the amount scaled up or down each interval will vary based on the timeliness of readiness and the updater will always try to make progress, even slowly.

If an update from newRc to oldRc is already in progress, we attempt to drive it to completion. If an error occurs at any step of the update, the error will be returned.

A scaling event (either up or down) is considered progress; if no progress is made within the config.Timeout, an error is returned.

TODO: make this handle performing a rollback of a partially completed rollout.

	// the new controller to the name of the old controller.
	RenameRollingUpdateCleanupPolicy RollingUpdaterCleanupPolicy = "Rename"
)

type RollingUpdaterConfig added in v0.16.0 

type RollingUpdaterConfig struct {
	// Out is a writer for progress output.

	// update.

	// Timeout is the time to wait for controller updates before giving up.
	Timeout time.Duration
	// MinReadySeconds is the number of seconds to wait after the pods are ready
	MinReadySeconds int32
	// CleanupPolicy defines the cleanup action to take after the deployment is
	// complete.
	CleanupPolicy RollingUpdaterCleanupPolicy
	// MaxUnavailable is the maximum number of pods that can be unavailable during the update.
	// Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%).
	// Absolute number is calculated from percentage by rounding up.
	// This can not be 0 if MaxSurge is 0.
	// By default, a fixed value of 1 is used.
	// Example: when this is set to 30%, the old RC can be scaled down to 70% of desired pods
	// immediately when the rolling update starts. Once new pods are ready, old RC
	// can be scaled down further, followed by scaling up the new RC, ensuring
	// that the total number of pods available at all times during the update is at
	// least 70% of desired pods.
	MaxUnavailable intstr.IntOrString
	// MaxSurge is the maximum number of pods that can be scheduled above the desired number of pods.
	// Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%).
	// This can not be 0 if MaxUnavailable is 0.
	// Absolute number is calculated from percentage by rounding up.
	// By default, a value of 1 is used.
	// Example: when this is set to 30%, the new RC can be scaled up immediately
	// when the rolling update starts, such that the total number of old and new pods do not exceed
	// 130% of desired pods. Once old pods have been killed, new RC can be scaled up
	// further, ensuring that total number of pods running at any time during
	// the update is atmost 130% of desired pods.
	MaxSurge intstr.IntOrString
	// OnProgress is invoked if set during each scale cycle, to allow the caller to perform additional logic or
	// abort the scale. If an error is returned the cleanup method will not be invoked. The percentage value
	// is a synthetic "progress" calculation that represents the approximate percentage completion.
	OnProgress func(oldRc, newRc *api.ReplicationController, percentage int) error
