Functions

func AddRequiredHeadersToRedirectedRequests 

func AddRequiredHeadersToRedirectedRequests(req *http.Request, via []*http.Request) error

func AuthTransport 

func AuthTransport(base http.RoundTripper, authConfig *cliconfig.AuthConfig, alwaysSetBasicAuth bool) http.RoundTripper

AuthTransport handles the auth layer when communicating with a v1 registry (private or official)

For private v1 registries, set alwaysSetBasicAuth to true.

For the official v1 registry, if there isn't already an Authorization header in the request, but there is an X-Docker-Token header set to true, then Basic Auth will be used to set the Authorization header. After sending the request with the provided base http.RoundTripper, if an X-Docker-Token header, representing a token, is present in the response, then it gets cached and sent in the Authorization header of all subsequent requests.

If the server sends a token without the client having requested it, it is ignored.

This RoundTripper also has a CancelRequest method important for correct timeout handling.
