Functions

func BlueF added in v0.5.0 

func BlueF(format string, a ...interface{}) string

func BoldF added in v0.5.0 

func BoldF(format string, a ...interface{}) string

func DeploymentProgressing 

func DeploymentProgressing(deployment *appsv1.Deployment, newStatus *appsv1.DeploymentStatus) bool

DeploymentProgressing reports progress for a deployment. Progress is estimated by comparing the current with the new status of the deployment that the controller is observing. More specifically, when new pods are scaled up or become available, or old pods are scaled down, then we consider the deployment is progressing.

func DeploymentTimedOut 

func DeploymentTimedOut(deployment *appsv1.Deployment, newStatus *appsv1.DeploymentStatus) bool

DeploymentTimedOut considers a deployment to have timed out once its condition that reports progress is older than progressDeadlineSeconds or a Progressing condition with a TimedOutReason reason already exists.

func DescribeEvents 

func DescribeEvents(el *corev1.EventList)

func DirExists 

func DirExists(path string) (bool, error)

func EqualIgnoreHash 

func EqualIgnoreHash(template1, template2 corev1.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 EventFieldSelectorFromResource 

func EventFieldSelectorFromResource(obj interface{}) string

func FileExists 

func FileExists(path string) (bool, error)

FileExists returns true if path exists

func FindNewReplicaSet 

func FindNewReplicaSet(deployment *appsv1.Deployment, rsList []*appsv1.ReplicaSet) (*appsv1.ReplicaSet, error)

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

func FindOldReplicaSets 

func FindOldReplicaSets(deployment *appsv1.Deployment, rsList []*appsv1.ReplicaSet) ([]*appsv1.ReplicaSet, []*appsv1.ReplicaSet, error)

FindOldReplicaSets returns the old replica sets targeted by the given Deployment, with the given 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 FormatEventSource 

func FormatEventSource(es corev1.EventSource) string

formatEventSource formats EventSource as a comma separated string excluding Host when empty

func GetAllReplicaSets 

func GetAllReplicaSets(ctx context.Context, deployment *appsv1.Deployment, c kubernetes.Interface) ([]*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 GetControllerOf 

func GetControllerOf(controllee metav1.Object) *metav1.OwnerReference

GetControllerOf returns the controllerRef if controllee has a controller, otherwise returns nil.

func GetDeploymentCondition 

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

GetDeploymentCondition returns the condition with the provided type.

func GetNewReplicaSetTemplate 

func GetNewReplicaSetTemplate(deployment *appsv1.Deployment) corev1.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.

func GetPodReplicaSetName 

func GetPodReplicaSetName(pod *corev1.Pod) string

func GetReference 

func GetReference(obj runtime.Object) (*corev1.ObjectReference, error)

func GreenF added in v0.5.0 

func GreenF(format string, a ...interface{}) string

func IsReplicaSetNew 

func IsReplicaSetNew(deployment *appsv1.Deployment, rsMap map[string]*appsv1.ReplicaSet, rsName string) (bool, error)

func ListEventsForObject 

func ListEventsForObject(ctx context.Context, client kubernetes.Interface, obj interface{}) (*corev1.EventList, error)

func ListPods 

func ListPods(deployment *appsv1.Deployment, rsList []*appsv1.ReplicaSet, getPodList PodListFunc) (*corev1.PodList, error)

ListPods returns a list of pods the given deployment targets. This needs a list of ReplicaSets for the Deployment, which can be found with ListReplicaSets(). Note that this does NOT attempt to reconcile ControllerRef (adopt/orphan), because only the controller itself should do that. However, it does filter out anything whose ControllerRef doesn't match.

func ListReplicaSets 

func ListReplicaSets(deployment *appsv1.Deployment, getRSList rsListFunc) ([]*appsv1.ReplicaSet, error)

ListReplicaSets returns a slice of RSes the given deployment targets. Note that this does NOT attempt to reconcile ControllerRef (adopt/orphan), because only the controller itself should do that. However, it does filter out anything whose ControllerRef doesn't match.

func RedF added in v0.5.0 

func RedF(format string, a ...interface{}) string

func Revision 

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

Revision returns the revision number of the input object.

func TranslateTimestampSince 

func TranslateTimestampSince(timestamp metav1.Time) string

func YellowF added in v0.5.0 

func YellowF(format string, a ...interface{}) string
