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 FromUnstructured

func FromUnstructured(objs []unstructured.Unstructured) ([]byte, error)

FromUnstructured takes a list of Unstructured objects and converts it into a YAML

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.

func JoinYaml

func JoinYaml(yamls ...[]byte) []byte

JoinYaml takes a list of YAML files and join them ensuring each YAML that the yaml separator goes on a new line by adding \n where necessary

func ToUnstructured

func ToUnstructured(rawyaml []byte) ([]unstructured.Unstructured, error)

ToUnstructured takes a YAML and converts it to a list of Unstructured objects
