Functions

func GetStringFromUnstructuredObj

func GetStringFromUnstructuredObj(input *unstructured.Unstructured, path string) (string, error)

func SplitRegistryAndRepository

func SplitRegistryAndRepository(name string) (registry, repository string)

SplitRegistryAndRepository refers to https://github.com/distribution/distribution/blob/v2.7.1/reference/normalize.go#L62 The reason for using this function here is due to this discussion: https://stackoverflow.com/a/37867949 If we use reference.Domain() and reference.Path() for parsing, the following problems will occur:

• "ealen/echo-server" is resolved to <registry: "ealen", repository : "echo-server">

Using the follow function ensures that the above image is parsed into the following content:

• "ealen/echo-server" is resolved to <registry: "", repository : "ealen/echo-server">
