Functions

func CreateObjectFromInfoFn added in v1.4.2

func CreateObjectFromInfoFn(info *kubectlResource.Info) (bool, error)

CreateObjectFromInfoFn is an implementation of createObjectFromInfo

func DeployApp added in v1.4.2

func DeployApp(spec *AppDeploymentSpec, client client.Interface) error

DeployApp deploys an app based on the given configuration. The app is deployed using the given client. App deployment consists of a deployment and an optional service. Both of them share common labels.

func DeployAppFromFile added in v1.4.2

func DeployAppFromFile(spec *AppDeploymentFromFileSpec,
	createObjectFromInfoFn createObjectFromInfo) (bool, error)

DeployAppFromFile deploys an app based on the given yaml or json file.

func EqualIgnoreHash added in v1.6.0

func EqualIgnoreHash(template1, template2 v1.PodTemplateSpec) bool

EqualIgnoreHash returns true if two given podTemplateSpec are equal, ignoring the diff in value of Labels[pod-template-hash] We ignore pod-template-hash because the hash result would be different upon podTemplateSpec API changes (e.g. the addition of a new field will cause the hash code to change) Note that we assume input podTemplateSpecs contain non-empty labels

func FindNewReplicaSet added in v1.6.0

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 v1.6.0

func FindOldReplicaSets(deployment *extensions.Deployment, rsList []*extensions.ReplicaSet,
	podList *v1.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. Logic taken from: https://github.com/kubernetes/kubernetes/blob/b5f9d56cab78ccaad2b726223ba8be5802026f0b/pkg/controller/deployment/util/deployment_util.go#L623

func GetNewReplicaSetTemplate added in v1.6.0

func GetNewReplicaSetTemplate(deployment *extensions.Deployment) v1.PodTemplateSpec

GetNewReplicaSetTemplate returns the desired PodTemplateSpec for the new ReplicaSet corresponding to the given ReplicaSet. Callers of this helper need to set the DefaultDeploymentUniqueLabelKey k/v pair.
