Functions

func WrapTransport

func WrapTransport(transport http.RoundTripper, url, username, password string) http.RoundTripper

* Given an existing http.RoundTripper such as http.DefaultTransport, build the * transport stack necessary to authenticate to the Docker registry API. This * adds in support for OAuth bearer tokens and HTTP Basic auth, and sets up * error handling this library relies on.

type AuthorizationChallenge

type AuthorizationChallenge struct {
	Scheme     string

type BasicTransport

type BasicTransport struct {
	Transport http.RoundTripper
	URL       string
	Username  string
	Password  string
}

func (*BasicTransport) RoundTrip

func (t *BasicTransport) RoundTrip(req *http.Request) (*http.Response, error)

type ErrorTransport

type ErrorTransport struct {
	Transport http.RoundTripper
}

func (*ErrorTransport) RoundTrip

func (t *ErrorTransport) RoundTrip(request *http.Request) (*http.Response, error)

type HttpStatusError

type HttpStatusError struct {
	Response *http.Response
	Body     []byte // Copied from `Response.Body` to avoid problems with unclosed bodies later. Nobody calls `err.Response.Body.Close()`, ever.
}

func (*HttpStatusError) Error

func (err *HttpStatusError) Error() string

type ManifestInfo

type ManifestInfo struct {
	SignedManifest *manifestV1.SignedManifest
	Digest         string
	RunAsRoot      bool
	Author         string
	Envs           []string
	Cmds           []string
	Labels         map[string]string
}

type Registry

type Registry struct {
	URL    string
	Client *httptrace.TraceClient
}

func NewInsecure

func NewInsecure(registryUrl, username, password, proxy string, trace httptrace.HTTPTrace) (*Registry, uint, error)

* Create a new Registry, as with New, using an http.Transport that disables * SSL certificate verification.

func NewSecure

func NewSecure(registryUrl, username, password, proxy string, trace httptrace.HTTPTrace) (*Registry, uint, error)

* Create a new Registry with the given URL and credentials, then Ping()s it * before returning it to verify that the registry is available. * * You can, alternately, construct a Registry manually by populating the fields. * This passes http.DefaultTransport to WrapTransport when creating the * http.Client.
