示例1: DetectContextFromRemoteURL

// DetectContextFromRemoteURL returns a context and in certain cases the name of the dockerfile to be used
// irrespective of user input.
// progressReader is only used if remoteURL is actually a URL (not empty, and not a Git endpoint).
func DetectContextFromRemoteURL(r io.ReadCloser, remoteURL string, createProgressReader func(in io.ReadCloser) io.ReadCloser) (context builder.ModifiableContext, dockerfileName string, err error) {
	switch {
	case remoteURL == "":
		context, err = builder.MakeTarSumContext(r)
	case urlutil.IsGitURL(remoteURL):
		context, err = builder.MakeGitContext(remoteURL)
	case urlutil.IsURL(remoteURL):
		context, err = builder.MakeRemoteContext(remoteURL, map[string]func(io.ReadCloser) (io.ReadCloser, error){
			httputils.MimeTypes.TextPlain: func(rc io.ReadCloser) (io.ReadCloser, error) {
				dockerfile, err := ioutil.ReadAll(rc)
				if err != nil {
					return nil, err
				}

				// dockerfileName is set to signal that the remote was interpreted as a single Dockerfile, in which case the caller
				// should use dockerfileName as the new name for the Dockerfile, irrespective of any other user input.
				dockerfileName = api.DefaultDockerfileName

				// TODO: return a context without tarsum
				return archive.Generate(dockerfileName, string(dockerfile))
			},
			// fallback handler (tar context)
			"": func(rc io.ReadCloser) (io.ReadCloser, error) {
