Functions

func Log

func Log(format string, args ...interface{})

* Pass log messages along to Go's "log" module.

func Quiet

func Quiet(format string, args ...interface{})

* Discard log messages silently.

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.

Types

type AuthorizationChallenge

type AuthorizationChallenge struct {
	Scheme     string
	Parameters map[string]string
}

AuthorizationChallenge carries information from a WWW-Authenticate response header.

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

func (*HTTPStatusError) Error

func (err *HTTPStatusError) Error() string

type LogfCallback

type LogfCallback func(format string, args ...interface{})

type Registry

type Registry struct {
	URL    string
	Client *http.Client
	Logf   LogfCallback
}

func New

func New(registryURL, username, password string) (*Registry, 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.

func NewInsecure

func NewInsecure(registryURL, username, password string) (*Registry, error)

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