Functions

func AddEtagToTag

func AddEtagToTag(tag, etag string) distribution.ManifestServiceOption

AddEtagToTag allows a client to supply an eTag to Get which will be used for a conditional HTTP request. If the eTag matches, a nil manifest and ErrManifestNotModified error will be returned. etag is automatically quoted when added to this map.

HandleErrorResponse returns error parsed from HTTP response for an unsuccessful HTTP response code (in the range 400 - 499 inclusive). An UnexpectedHTTPStatusError returned for response code outside of expected range.

func NewRepository

func NewRepository(ctx context.Context, name reference.Named, baseURL string, transport http.RoundTripper) (distribution.Repository, error)

NewRepository creates a new Repository for the given repository name and base URL.

func ReturnContentDigest

func ReturnContentDigest(dgst *digest.Digest) distribution.ManifestServiceOption

ReturnContentDigest allows a client to set a the content digest on a successful request from the 'Docker-Content-Digest' header. This returned digest is represents the digest which the registry uses to refer to the content and can be used to delete the content.

func SuccessStatus

func SuccessStatus(status int) bool

	Repositories(ctx context.Context, repos []string, last string) (n int, err error)
}

Registry provides an interface for calling Repositories, which returns a catalog of repositories.

func NewRegistry

func NewRegistry(ctx context.Context, baseURL string, transport http.RoundTripper) (Registry, error)

NewRegistry creates a registry namespace which can be used to get a listing of repositories

type UnexpectedHTTPResponseError

type UnexpectedHTTPResponseError struct {
	ParseErr   error
	StatusCode int
	Response   []byte
}

func (*UnexpectedHTTPResponseError) Error

func (e *UnexpectedHTTPResponseError) Error() string

type UnexpectedHTTPStatusError

type UnexpectedHTTPStatusError struct {
	Status string
}

UnexpectedHTTPStatusError is returned when an unexpected HTTP status is returned when making a registry api call.

func (*UnexpectedHTTPStatusError) Error

func (e *UnexpectedHTTPStatusError) Error() string
