Functions

func FixImages

func FixImages(objs []unstructured.Unstructured, alterImageFunc func(image string) (string, error)) ([]unstructured.Unstructured, error)

FixImages alters images using the give alter func NB. The implemented approach is specific for the provider components YAML & for the cert-manager manifest; it is not intended to cover all the possible objects used to deploy containers existing in Kubernetes.

func InspectImages

func InspectImages(objs []unstructured.Unstructured) ([]string, error)

InspectImages identifies the container images required to install the objects defined in the objs. NB. The implemented approach is specific for the provider components YAML & for the cert-manager manifest; it is not intended to cover all the possible objects used to deploy containers existing in Kubernetes.

func IsClusterResource

func IsClusterResource(kind string) bool

IsClusterResource returns true if the resource kind is cluster wide (not namespaced).

func IsResourceNamespaced

func IsResourceNamespaced(kind string) bool

IsResourceNamespaced returns true if the resource kind is namespaced.

func IsSharedResource

func IsSharedResource(o unstructured.Unstructured) bool

IsSharedResource returns true if the resource lifecycle is shared.
