Constants

const (
	// Registry is the DHI registry hostname
	Registry = "dhi.io"
	// DockerHubDomain is the canonical Docker Hub domain
	DockerHubDomain = "docker.io"
	// LibraryPrefix is the path prefix for official Docker Hub images
	LibraryPrefix = "library/"
)

Variables

View Source 
var ErrNotEligible = errors.New("image not eligible for DHI mapping")

ErrNotEligible is returned when an image reference cannot be mapped to DHI.

Functions

func CanMapToDHI 

func CanMapToDHI(ref reference.Named) bool

CanMapToDHI returns true if the reference is a docker.io library image that may have a DHI equivalent. Only official images (docker.io/library/*) are eligible for DHI mapping.

func MapToDHI 

func MapToDHI(ref reference.Named) (reference.Named, error)

MapToDHI converts a docker.io library reference to its dhi.io equivalent. Example: docker.io/library/alpine:3.18 -> dhi.io/alpine:3.18 Returns ErrNotEligible if the reference cannot be mapped (use CanMapToDHI to check first).
