Functions

func FindNewReplicaSet added in v1.2.0 

func FindNewReplicaSet(deployment *extensions.Deployment, rsList []extensions.ReplicaSet) (*extensions.ReplicaSet, error)

FindNewReplicaSet returns the new RS this given deployment targets (the one with the same pod template).

func FindOldReplicaSets added in v1.2.0 

func FindOldReplicaSets(deployment *extensions.Deployment, rsList []extensions.ReplicaSet, podList *api.PodList) ([]*extensions.ReplicaSet, []*extensions.ReplicaSet, error)

FindOldReplicaSets returns the old replica sets targeted by the given Deployment, with the given PodList and slice of RSes. 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 GetActualReplicaCountForReplicaSets added in v1.2.0 

func GetActualReplicaCountForReplicaSets(replicaSets []*extensions.ReplicaSet) int32

GetActualReplicaCountForReplicaSets returns the sum of actual replicas of the given replica sets.

func GetAllReplicaSets 

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

GetAllReplicaSets returns the old and new replica sets targeted by the given Deployment. It gets 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. The third returned value is the new replica set, and it may be nil if it doesn't exist yet.

func GetAvailablePodsForReplicaSets added in v1.2.0 

func GetAvailablePodsForReplicaSets(c clientset.Interface, rss []*extensions.ReplicaSet, minReadySeconds int32) (int32, error)

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

func GetNewReplicaSet added in v1.2.0 

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 GetNewReplicaSetTemplate added in v1.2.0 

func GetNewReplicaSetTemplate(deployment *extensions.Deployment) api.PodTemplateSpec

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

func GetOldReplicaSets added in v1.2.0 

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 GetPodsForReplicaSets added in v1.2.0 

func GetPodsForReplicaSets(c clientset.Interface, replicaSets []*extensions.ReplicaSet) ([]api.Pod, error)

func GetReplicaCountForReplicaSets added in v1.2.0 

func GetReplicaCountForReplicaSets(replicaSets []*extensions.ReplicaSet) int32

Returns the sum of Replicas of the given replica sets.

func IsPodAvailable added in v1.2.0 

func IsPodAvailable(pod *api.Pod, minReadySeconds int32) bool

func IsRollingUpdate added in v1.2.0 

func IsRollingUpdate(deployment *extensions.Deployment) bool

func LabelPodsWithHash added in v1.2.0 

func LabelPodsWithHash(podList *api.PodList, rs *extensions.ReplicaSet, c clientset.Interface, namespace, hash string) (bool, error)

LabelPodsWithHash labels all pods in the given podList with the new hash label. The returned bool value can be used to tell if all pods are actually labeled.

func ListPods added in v1.2.0 

func ListPods(deployment *extensions.Deployment, getPodList podListFunc) (*api.PodList, error)

ListPods returns a list of pods the given deployment targets.

func ListReplicaSets added in v1.2.0 

func ListReplicaSets(deployment *extensions.Deployment, getRSList rsListFunc) ([]extensions.ReplicaSet, error)

ListReplicaSets returns a slice of RSes the given deployment targets.

func NewRSNewReplicas added in v1.2.0 

func NewRSNewReplicas(deployment *extensions.Deployment, allRSs []*extensions.ReplicaSet, newRS *extensions.ReplicaSet) (int32, 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 ResolveFenceposts added in v1.2.0 

func ResolveFenceposts(maxSurge, maxUnavailable *intstrutil.IntOrString, desired int32) (int32, int32, error)

ResolveFenceposts resolves both maxSurge and maxUnavailable. This needs to happen in one step. For example:

2 desired, max unavailable 1%, surge 0% - should scale old(-1), then new(+1), then old(-1), then new(+1) 1 desired, max unavailable 1%, surge 0% - should scale old(-1), then new(+1) 2 desired, max unavailable 25%, surge 1% - should scale new(+1), then old(-1), then new(+1), then old(-1) 1 desired, max unavailable 25%, surge 1% - should scale new(+1), then old(-1) 2 desired, max unavailable 0%, surge 1% - should scale new(+1), then old(-1), then new(+1), then old(-1) 1 desired, max unavailable 0%, surge 1% - should scale new(+1), then old(-1)

func Revision added in v1.2.0 

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

Revision returns the revision number of the input replica set

func SetFromReplicaSetTemplate added in v1.2.0 

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

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

func WaitForObservedDeployment added in v1.2.0 

func WaitForObservedDeployment(getDeploymentFunc func() (*extensions.Deployment, error), desiredGeneration int64, interval, timeout time.Duration) error

Polls for deployment to be updated so that deployment.Status.ObservedGeneration >= desiredGeneration. Returns error if polling timesout.

func WaitForPodsHashPopulated added in v1.2.0 

func WaitForPodsHashPopulated(c clientset.Interface, desiredGeneration int64, namespace, name string) error

func WaitForReplicaSetUpdated added in v1.2.0 

func WaitForReplicaSetUpdated(c clientset.Interface, desiredGeneration int64, namespace, name string) error
