Constants

const (
	// JobSyncActionReconciling when the Job's pod creation/deletion expectations
	// are unsatisfied and the controller is waiting for issued Pod
	// creation/deletions to complete.
	JobSyncActionReconciling = "reconciling"
	// JobSyncActionTracking when the Job's pod creation/deletion expectations
	// are satisfied and the number of active Pods matches expectations (i.e. no
	// pod creation/deletions issued in this sync). This is expected to be the
	// action in most of the syncs.
	JobSyncActionTracking = "tracking"
	// JobSyncActionPodsCreated when the controller creates Pods. This can happen
	// when the number of active Pods is less than the wanted Job parallelism.
	JobSyncActionPodsCreated = "pods_created"
	// JobSyncActionPodsDeleted when the controller deletes Pods. This can happen
	// if a Job is suspended or if the number of active Pods is more than

Possible values for the "action" label in the above metrics.

const JobControllerSubsystem = "job_controller"

JobControllerSubsystem - subsystem name used for this controller.
