Documentation

Overview

Package ref is used to define references. References default to remote registry references (registry:port/repo:tag). Schemes can be included in front of the reference for different reference types.

Functions

func EqualRegistry

func EqualRegistry(a, b Ref) bool

EqualRegistry compares the registry between two references.

func EqualRepository

func EqualRepository(a, b Ref) bool

EqualRepository compares the repository between two references.

Types

type Ref

type Ref struct {
	Scheme     string // Scheme is the type of reference, "reg" or "ocidir".
	Reference  string // Reference is the unparsed string or common name.
	Registry   string // Registry is the server for the "reg" scheme.
	Repository string // Repository is the path on the registry for the "reg" scheme.
	Tag        string // Tag is a mutable tag for a reference.
	Digest     string // Digest is an immutable hash for a reference.
	Path       string // Path is the directory of the OCI Layout for "ocidir".
}

Ref is a reference to a registry/repository. Direct access to the contents of this struct should not be assumed.

func New

func New(parse string) (Ref, error)

New returns a reference based on the scheme (defaulting to "reg").

func NewHost

func NewHost(parse string) (Ref, error)

NewHost returns a Reg for a registry hostname or equivalent. The ocidir schema equivalent is the path.

func (Ref) CommonName

func (r Ref) CommonName() string

CommonName outputs a parsable name from a reference.

func (Ref) IsSet

func (r Ref) IsSet() bool

IsSet returns true if needed values are defined for a specific reference.

func (Ref) IsSetRepo

func (r Ref) IsSetRepo() bool

IsSetRepo returns true when the ref includes values for a specific repository.

func (Ref) IsZero

func (r Ref) IsZero() bool

IsZero returns true if ref is unset.

func (Ref) SetDigest

func (r Ref) SetDigest(digest string) Ref

SetDigest returns a ref with the requested digest set. The tag will be unset and the reference value will be reset.

func (Ref) SetTag

func (r Ref) SetTag(tag string) Ref

SetTag returns a ref with the requested tag set. The digest will be unset and the reference value will be reset.

func (Ref) ToReg

func (r Ref) ToReg() Ref

ToReg converts a reference to a registry like syntax.
