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.

A set of common functions needed by cmd/kubectl and pkg/kubectl packages.

type RollingUpdater 

type RollingUpdater struct {

func NewRollingUpdater 

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

NewRollingUpdater creates a RollingUpdater from a client.

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.
