Functions

func GetAllReplicaSets

func GetAllReplicaSets(deployment *appsv1.Deployment, c appsclient.AppsV1Interface) ([]*appsv1.ReplicaSet, []*appsv1.ReplicaSet, *appsv1.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 GetDeploymentCondition

func GetDeploymentCondition(status appsv1.DeploymentStatus, condType appsv1.DeploymentConditionType) *appsv1.DeploymentCondition

GetDeploymentCondition returns the condition with the provided type.

func ResolveFenceposts

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

func Revision(obj runtime.Object) (int64, error)

Revision returns the revision number of the input object.
