示例1: cloudHandler

// cloudHandler returns a handler that responds with the cloud config for the
// requester.
func cloudHandler(srv server.Server) ContextHandler {
	fn := func(ctx context.Context, w http.ResponseWriter, req *http.Request) {
		group, err := groupFromContext(ctx)
		if err != nil || group.Profile == "" {
			http.NotFound(w, req)
			return
		}
		profile, err := srv.ProfileGet(ctx, &pb.ProfileGetRequest{Id: group.Profile})
		if err != nil || profile.CloudId == "" {
			http.NotFound(w, req)
			return
		}
		contents, err := srv.CloudGet(ctx, profile.CloudId)
		if err != nil {
			http.NotFound(w, req)
			return
		}

		// collect data for rendering
		data := make(map[string]interface{})
		if group.Metadata != nil {
			err = json.Unmarshal(group.Metadata, &data)
			if err != nil {
				log.Errorf("error unmarshalling metadata: %v", err)
				http.NotFound(w, req)
				return
			}
		}
		for key, value := range group.Selector {
			data[strings.ToLower(key)] = value
		}

		// render the template of a cloud config with data
		var buf bytes.Buffer
		err = renderTemplate(&buf, data, contents)
		if err != nil {
			http.NotFound(w, req)
			return
		}

		config := buf.String()
		if !cloudinit.IsCloudConfig(config) && !cloudinit.IsScript(config) {
			log.Error("error parsing user-data")
			http.NotFound(w, req)
			return
		}
