Overview ¶

Package kubectl is a set of libraries that are used by the kubectl command line tool. They are separated out into a library to support unit testing. Most functionality should be included in this package, and the main kubectl should really just be an entry point.

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

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.
