Variables

var CoreV1Namespace = corev1.SchemeGroupVersion.WithKind("Namespace")

CoreV1Namespace is Namespace GVK.

var RBACGroupKind = map[schema.GroupKind]bool{
	{Group: rbacv1.GroupName, Kind: "Role"}:               true,
	{Group: rbacv1.GroupName, Kind: "ClusterRole"}:        true,
	{Group: rbacv1.GroupName, Kind: "RoleBinding"}:        true,
	{Group: rbacv1.GroupName, Kind: "ClusterRoleBinding"}: true,
}

RBACGroupKind is a map of the RBAC resources. Needed since name validation is different than other k8s resources.

Functions

func Hash

func Hash(objs []ObjMetadata) (string, error)

CalcHash returns a hash of the sorted strings from the object metadata, or an error if one occurred.

func InfoToUnstructured

func InfoToUnstructured(info *resource.Info) *unstructured.Unstructured

func InfosToUnstructureds

func InfosToUnstructureds(infos []*resource.Info) []*unstructured.Unstructured

func SetEquals

func SetEquals(setA []ObjMetadata, setB []ObjMetadata) bool

SetEquals returns true if the slice of objects in setA equals the slice of objects in setB.

func UnstructuredToInfo

func UnstructuredToInfo(obj *unstructured.Unstructured) (*resource.Info, error)

func UnstructuredsToInfos

func UnstructuredsToInfos(objs []*unstructured.Unstructured) ([]*resource.Info, error)

Types

type ObjMetadata

type ObjMetadata struct {
	Namespace string
	Name      string
	GroupKind schema.GroupKind
}

ObjMetadata organizes and stores the indentifying information for an object. This struct (as a string) is stored in a inventory object to keep track of sets of applied objects.

func CreateObjMetadata

func CreateObjMetadata(namespace string, name string, gk schema.GroupKind) (ObjMetadata, error)

CreateObjMetadata returns a pointer to an ObjMetadata struct filled with the passed values. This function normalizes and validates the passed fields and returns an error for bad parameters.

func InfoToObjMeta

func InfoToObjMeta(info *resource.Info) (ObjMetadata, error)

InfoToObjMeta takes information from the provided info and returns an ObjMetadata that identifies the resource.

func InfosToObjMetas

func InfosToObjMetas(infos []*resource.Info) ([]ObjMetadata, error)

BuildObjectMetadata returns object metadata (ObjMetadata) for the passed objects (infos).

func ParseObjMetadata

func ParseObjMetadata(s string) (ObjMetadata, error)

ParseObjMetadata takes a string, splits it into its four fields, and returns an ObjMetadata struct storing the four fields. Example inventory string:

test-namespace_test-name_apps_ReplicaSet

Returns an error if unable to parse and create the ObjMetadata struct.

NOTE: name field can contain double underscore (__), which represents a colon. RBAC resources can have this additional character (:) in their name.

func RuntimeToObjMeta

func RuntimeToObjMeta(obj runtime.Object) ObjMetadata

func SetDiff

func SetDiff(setA []ObjMetadata, setB []ObjMetadata) []ObjMetadata

SetDiff returns the slice of objects that exist in "a", but do not exist in "b" (A - B).

func Union

func Union(setA []ObjMetadata, setB []ObjMetadata) []ObjMetadata

Union returns the slice of objects that is the set of unique items of the merging of set A and set B.

func UnstructuredToObjMeta

func UnstructuredToObjMeta(obj *unstructured.Unstructured) ObjMetadata

func UnstructuredsToObjMetas

func UnstructuredsToObjMetas(objs []*unstructured.Unstructured) []ObjMetadata

func (*ObjMetadata) Equals

func (o *ObjMetadata) Equals(other *ObjMetadata) bool

Equals compares two ObjMetadata and returns true if they are equal. This does not contain any special treatment for the extensions API group.

func (*ObjMetadata) String

func (o *ObjMetadata) String() string

String create a string version of the ObjMetadata struct. For RBAC resources, the "name" field transcodes ":" into double underscore for valid storing as the label of a ConfigMap.
