Functions

func CachedConfigMapGetter 

func CachedConfigMapGetter(client corev1client.ConfigMapsGetter, listers KubeInformersForNamespaces) corev1client.ConfigMapsGetter

func CachedSecretGetter 

func CachedSecretGetter(client corev1client.SecretsGetter, listers KubeInformersForNamespaces) corev1client.SecretsGetter

func EnsureFinalizer 

func EnsureFinalizer(ctx context.Context, client OperatorClientWithFinalizers, controllerName string) error

EnsureFinalizer adds a new finalizer to the operator CR, if it does not exists. No-op otherwise. The finalizer name is computed from the controller name and operator name ($OPERATOR_NAME or os.Args[0]) It re-tries on conflicts.

func FindCondition

func FlagsFromUnstructured 

func FlagsFromUnstructured(unstructuredArgs map[string]interface{}) (map[string][]string, error)

FlagsFromUnstructured process the unstructured arguments usually retrieved from an operator's configuration file under a specific key. There are only two supported/valid types for arguments, that is []sting and/or string. Passing a different type yield an error.

Use ToFlagSlice function to get a slice of string flags.

func RemoveCondition(conditions *[]metav1.Condition, conditionType string)

func RemoveFinalizer 

func RemoveFinalizer(ctx context.Context, client OperatorClientWithFinalizers, controllerName string) error

RemoveFinalizer removes a finalizer from the operator CR, if it is there. No-op otherwise. The finalizer name is computed from the controller name and operator name ($OPERATOR_NAME or os.Args[0]) It re-tries on conflicts.

func RemoveOperatorCondition 

func RemoveOperatorCondition(conditions *[]operatorv1.OperatorCondition, conditionType string)

func SetCondition

func ToFlagSlice 

func ToFlagSlice(args map[string][]string) []string

ToFlagSlice transforms the provided arguments to a slice of string flags. A flag name is taken directly from the key and the value is simply attached. A flag is repeated iff it has more than one value.

func UpdateSpec
