Overview

Package kubectl provides the functions used by the kubectl command line tool under k8s.io/kubernetes/cmd. The functions are kept in this package to better support unit testing. The main() method for kubectl is only an entry point and should contain no functionality.

Constants

View Source 
const (
	ChangeCauseAnnotation = "kubernetes.io/change-cause"
)

Variables

View Source 
var ErrContainerTerminated = fmt.Errorf("container terminated")

ErrContainerTerminated is returned by PodContainerRunning in the intermediate state where the pod indicates it's still running, but its container is already terminated

View Source 
var ErrPodCompleted = fmt.Errorf("pod ran to completion")

func (*RollingUpdater) Update 

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.

type RollingUpdaterCleanupPolicy

	// RenameRollingUpdateCleanupPolicy means delete the old controller, and rename
	// the new controller to the name of the old controller.
	RenameRollingUpdateCleanupPolicy RollingUpdaterCleanupPolicy = "Rename"
)

type RollingUpdaterConfig 

type RollingUpdaterConfig struct {
	// Out is a writer for progress output.
	Out io.Writer
	// OldRC is an existing controller to be replaced.
	OldRc *corev1.ReplicationController
	// NewRc is a controller that will take ownership of updated pods (will be
	// created if needed).
	NewRc *corev1.ReplicationController
	// UpdatePeriod is the time to wait between individual pod updates.
	UpdatePeriod time.Duration
	// Interval is the time to wait between polling controller status after
	// update.
	Interval time.Duration
	// 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.
