无法连接到Windows 7上的Docker守护进程

我试图部署一个应用程序在谷歌云，只是按照https://cloud.google.com/nodejs/getting-started/hello-world#running_hello_world教程，但每次运行：

gcloud --verbosity debug preview app deploy app.yaml --promote 

我收到一条消息错误：

 Copying certificates for secure access. You may be prompted to create an SSH key pair. DEBUG: Loaded Command Group: ['gcloud', 'compute', 'copy_files'] DEBUG: Detected docker environment variables: DOCKER_HOST=tcp://104.197.75.48:2376, DOCKER_CERT_PATH=tmpurmvdk, DOCKER_TLS_VERIFY=True INFO: Starting new HTTPS connection (1): 104.197.75.48 DEBUG: Failed to connect to Docker daemon due to an SSL problem: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590) 

我错过了什么？
