func GetObjectStatus

func GetObjectStatus(obj map[string]interface{}) (map[string]interface{}, error)

GetObjectStatus returns the status of a given object, if any.

func GetUnstructuredObject

func GetUnstructuredObject(scheme *runtime.Scheme, obj runtime.Object) (*unstructured.Unstructured, error)

GetUnstructuredObject converts the given Object into Unstructured type.

func IsInitialized

func IsInitialized(scheme *runtime.Scheme, obj runtime.Object) (bool, error)

IsInitialized checks if an object is initialized by checking if there's any status condition.

func NamespacedNames

func NamespacedNames(instances client.ObjectList) ([]types.NamespacedName, error)

NamespacedNames converts an ObjectList to a slice of NamespacedNames.

func NamespacedNamesDiff

func NamespacedNamesDiff(a, b []types.NamespacedName) []types.NamespacedName

NamespacedNamesDiff takes two slices of NamespacedNames and returns a slice of elements from the list a that are not present in list b.

func NestedFieldNoCopy

func NestedFieldNoCopy(obj map[string]interface{}, fields ...string) (interface{}, bool, error)

NestedFieldNoCopy returns the nested field from a given Object. The second returned value is true if the field is found, else false.
