Functions

func AddStringToSliceIfMissing

func AddStringToSliceIfMissing(slice []string, toAdd string) []string

AddStringToSliceIfMissing returns a copy of the passed string slice with the toAdd string added if it did not exist. If toAdd already exists in the passed slice, the original slice is returned. The new string will be appended to the end of the slice and the order of the original elements will match the order of the original slice. If a nil slice is passed, a new slice will be created containing only toAdd.

func CreateAndStartRecorder

func CreateAndStartRecorder(kubeclientset kubernetes.Interface, name string) record.EventRecorder

CreateAndStartRecorder creates and starts a new recorder with the given name

func GetNodeAPIVersion

func GetNodeAPIVersion(node *corev1.Node, pods []*corev1.Pod) string

GetNodeAPIVersion returns the version of the static pod running the api server

func GetNodeKubeControllerManagerVersion

func GetNodeKubeControllerManagerVersion(node *corev1.Node, pods []*corev1.Pod) string

GetNodeKubeControllerManagerVersion returns the version of the static pod running the kube controller manager

func GetNodeSchedulerVersion

func GetNodeSchedulerVersion(node *corev1.Node, pods []*corev1.Pod) string

GetNodeSchedulerVersion returns the version of the static pod running the scheduler

func IndexByIDKeyFun

func IndexByIDKeyFun() cache.Indexers

IndexByIDKeyFun returns a function for indexing a cache by ID

func MetaResourceNamespaceKeyFunc

func MetaResourceNamespaceKeyFunc(kind string, obj interface{}) (string, error)

MetaResourceNamespaceKeyFunc is a convenient KeyFunc which knows how to make keys for API objects which implement meta.Interface. The key uses the format <kind>/<namespace>/<name> unless <namespace> is empty, then it's <kind>/<name>.

func NodeIsReady

func NodeIsReady(node *corev1.Node) bool

NodeIsReady returns true if the given node has a Ready status, else false. See https://kubernetes.io/docs/concepts/nodes/node/#condition for more info.

func NodeIsTargetKubernetesVersion

func NodeIsTargetKubernetesVersion(cup *provisionhksv3.ClusterUpgrade, node *corev1.Node, pods []*corev1.Pod) bool

NodeIsTargetKubernetesVersion checks if the current node version matches the target version of the cluster upgrade that is being processed. This only checks that the kubelet is up to date on worker nodes, and that on masters kubelet and static pods are at the desired version. NOTE: this should only be called with upgrades of type Kubernetes

func RemoveStringFromSlice

func RemoveStringFromSlice(slice []string, toRemove string) []string

RemoveStringFromSlice returns a copy of the passed string slice with all instances of the toRemove string removed if it exists. The order of the remaining elements will match the order of the original slice. If a nil slice is passed, nil will be returned.

func SplitMetaResourceNamespaceKeyFunc

func SplitMetaResourceNamespaceKeyFunc(key string) (kind, namespace, name string, err error)

SplitMetaResourceNamespaceKeyFunc returns the kind, namespace and name that MetaResourceNamespaceKeyFunc encoded into key.

func StringMapsAreEqual

func StringMapsAreEqual(a, b map[string]string) bool

StringMapsAreEqual compares two string maps, checking the first map to see if each of the keys are present and contains the same values as the second map

func StringSliceContains

func StringSliceContains(slice []string, checkFor string) bool

StringSliceContains returns true if the passed slice contains the checkFor string, else false.

func StringSlicesAreEqual

func StringSlicesAreEqual(a, b []string) bool

StringSlicesAreEqual returns true if slice a and b are equal, else false. If a or b is nil, they are equal if both are nil. If two slices contain the same elements but in a different order, they are not equal.
