var DefaultUpdateRetry = wait.Backoff{
	Steps:    10,
	Duration: 500 * time.Millisecond,
	Factor:   1.0,
	Jitter:   0.1,

DefaultUpdateRetry is the recommended retry for a failure to update a resource or ensuring that the changes from an update have been committed and have become consistent.

Functions

func AddFinalizer

func AddFinalizer(o *v1.ObjectMeta, finalizer string)

AddFinalizer - add finalizer (if it wasn't added before)

func ApplyDeployment

func ApplyDeployment(c kubernetes.Interface, d *appsv1.Deployment) (*appsv1.Deployment, error)

ApplyDeployment creates or updates existing deployment

func ApplySecret

func ApplySecret(c kubernetes.Interface, s *corev1.Secret) (*corev1.Secret, error)

ApplySecret creates or updates if exist kubernetes secret

func ApplyService

func ApplyService(c kubernetes.Interface, s *corev1.Service) (*corev1.Service, error)

ApplyService creates or updates existing service

func GenerateHex

func GenerateHex(dataLen int) (string, error)

GenerateHex generates a hex string using random data of the given length.

func GenerateName

func GenerateName(base string) string

GenerateName returns the given base name plus a random suffix of five alphanumerics and a hyphen separator. The string is guaranteed to not exceed the length of a standard Kubernetes name (253 characters). e.g., GenerateName("foo") would return a value similar to: "foo-a1b2c".

If base string length exceeds 247 (253 - 6) characters, it will be truncated to 247 characters before adding random suffix e.g., GenerateName("foo...ververylongstringof253chars") would return value similar to:

"foo...ververylongstringof25-x8y9z"

func GeneratePassword

func GeneratePassword(dataLen int) (string, error)

GeneratePassword generates a password using random data of the given length, then encodes to a base64 string.

func HasFinalizer

func HasFinalizer(o *v1.ObjectMeta, finalizer string) bool

HasFinalizer - check if given instance has a given finalizer

func IfEmptyString

func IfEmptyString(s, r string) string

IfEmptyString test input string and if empty, i.e = "", return a replacement string

func LatestDeploymentCondition

func LatestDeploymentCondition(conditions []appsv1.DeploymentCondition) appsv1.DeploymentCondition

LatestDeploymentCondition

func ObjectReference

func ObjectReference(o metav1.ObjectMeta, apiVersion, kind string) *corev1.ObjectReference

ObjectReference from provided ObjectMeta, apiVersion and kind

func ObjectToOwnerReference

func ObjectToOwnerReference(r *corev1.ObjectReference) *metav1.OwnerReference

ObjectToOwnerReference converts core ObjectReference to meta OwnerReference

func RemoveFinalizer

func RemoveFinalizer(o *v1.ObjectMeta, finalizer string)

RemoveFinalizer - from the list of kubernetes object finalizers

func SecretData

func SecretData(client kubernetes.Interface, namespace string, ks corev1.SecretKeySelector) ([]byte, error)
