func Differs

func Differs(list []string, s string) bool

func EnsureLabelsForConfigMap

func EnsureLabelsForConfigMap(cm *corev1.ConfigMap, labels map[string]string)

func EnsureLabelsForRoute

func EnsureLabelsForRoute(r *ocproute.Route, labels map[string]string)

func EnsureLabelsForSecret

func EnsureLabelsForSecret(secret *corev1.Secret, labels map[string]string)

func EnsureLabelsForService

func EnsureLabelsForService(s *corev1.Service, labels map[string]string)

func FindMinSemver

func FindMinSemver(annotations map[string]string, curChannel string) string

FindMinSemver returns the minimal semantic version from annotations

func FindSemantic

func FindSemantic(input string) string

FindSemantic checks if a given string contains a substring which is a valid semantic version, and returns that substring

func GetInstallScope

func GetInstallScope() string

GetInstallScope returns the scope of the installation

func GetIsolatedMode

func GetIsolatedMode() bool

func GetOperatorNamespace

func GetOperatorNamespace() string

GetOperatorNamespace returns the Namespace of the operator

func GetWatchNamespace

func GetWatchNamespace() string

GetWatchNamespace returns the Namespace of the operator

func GetoperatorCheckerMode

func GetoperatorCheckerMode() bool

func MergeCR

func MergeCR(defaultCR, changedCR []byte) map[string]interface{}

MergeCR deep merge two custom resource spec

func ObjectToNewUnstructured

func ObjectToNewUnstructured(obj interface{}) (*unstructured.Unstructured, error)

func ResourceExists

func ResourceExists(dc discovery.DiscoveryInterface, apiGroupVersion, kind string) (bool, error)

ResourceExists returns true if the given resource kind exists in the given api groupversion

func ResourceNamespaced

func ResourceNamespaced(dc discovery.DiscoveryInterface, apiGroupVersion, kind string) (bool, error)

ResourceNamespaced returns true if the given resource is namespaced

func SanitizeObjectString

func SanitizeObjectString(jsonPath string, data interface{}) (string, error)

SanitizeObjectString takes a string, i.e. .metadata.namespace, and a K8s object and returns a string got from K8s object. The required string is sanitized because the values are YAML fields in a K8s object. Ensures that:

1. the field actually exists, otherwise returns an error
2. extracts the value from the K8s Service's field, the value will be stringified

func StringSliceContentEqual

func StringSliceContentEqual(a, b []string) bool

StringSliceContentEqual checks if the contant from two string slice are the same

func WaitTimeout

func WaitTimeout(wg *sync.WaitGroup, timeout time.Duration) bool

WaitTimeout waits for the waitgroup for the specified max timeout. Returns true if waiting timed out.
