Functions

func GetAvailablePodsForReplicaSets

func GetAvailablePodsForReplicaSets(c clientset.Interface, rss []*extensions.ReplicaSet, minReadySeconds int) (int, error)

Returns the number of available pods corresponding to the given replica sets.

func GetNewReplicaSet

func GetNewReplicaSet(deployment extensions.Deployment, c clientset.Interface) (*extensions.ReplicaSet, error)

GetNewReplicaSet returns a replica set that matches the intent of the given deployment; get ReplicaSetList from client interface. Returns nil if the new replica set doesn't exist yet.

func GetNewReplicaSetFromList

func GetNewReplicaSetFromList(deployment extensions.Deployment, c clientset.Interface, getRSList func(string, api.ListOptions) ([]extensions.ReplicaSet, error)) (*extensions.ReplicaSet, error)

GetNewReplicaSetFromList returns a replica set that matches the intent of the given deployment; get ReplicaSetList with the input function. Returns nil if the new replica set doesn't exist yet.

func GetNewReplicaSetTemplate

func GetNewReplicaSetTemplate(deployment extensions.Deployment) api.PodTemplateSpec

Returns the desired PodTemplateSpec for the new ReplicaSet corresponding to the given ReplicaSet.

func GetOldReplicaSets

func GetOldReplicaSets(deployment extensions.Deployment, c clientset.Interface) ([]*extensions.ReplicaSet, []*extensions.ReplicaSet, error)

GetOldReplicaSets returns the old replica sets targeted by the given Deployment; get PodList and ReplicaSetList from client interface. Note that the first set of old replica sets doesn't include the ones with no pods, and the second set of old replica sets include all old replica sets.

func GetOldReplicaSetsFromLists

func GetOldReplicaSetsFromLists(deployment extensions.Deployment, c clientset.Interface, getPodList func(string, api.ListOptions) (*api.PodList, error), getRSList func(string, api.ListOptions) ([]extensions.ReplicaSet, error)) ([]*extensions.ReplicaSet, []*extensions.ReplicaSet, error)

GetOldReplicaSetsFromLists returns two sets of old replica sets targeted by the given Deployment; get PodList and ReplicaSetList with input functions. Note that the first set of old replica sets doesn't include the ones with no pods, and the second set of old replica sets include all old replica sets.

func GetReplicaCountForReplicaSets

func GetReplicaCountForReplicaSets(replicaSets []*extensions.ReplicaSet) int

Returns the sum of Replicas of the given replica sets.

func IsRollingUpdate

func IsRollingUpdate(deployment *extensions.Deployment) bool

func NewRSNewReplicas

func NewRSNewReplicas(deployment *extensions.Deployment, allRSs []*extensions.ReplicaSet, newRS *extensions.ReplicaSet) (int, error)

NewRSNewReplicas calculates the number of replicas a deployment's new RS should have. When one of the followings is true, we're rolling out the deployment; otherwise, we're scaling it. 1) The new RS is saturated: newRS's replicas == deployment's replicas 2) Max number of pods allowed is reached: deployment's replicas + maxSurge == all RSs' replicas

func Revision

func Revision(rs *extensions.ReplicaSet) (int64, error)

Revision returns the revision number of the input replica set

func SetFromReplicaSetTemplate

func SetFromReplicaSetTemplate(deployment *extensions.Deployment, template api.PodTemplateSpec) *extensions.Deployment

SetFromReplicaSetTemplate sets the desired PodTemplateSpec from a replica set template to the given deployment.
