Question

我尝试使用gcloud预览应用运行命令预览Go docker（App Engine ManagedVM）应用。

但我一直收到这个错误：

ERROR: (gcloud.preview.app.run) DevAppSever failed with error code [1]

我已经确认docker已启动并正在使用 boot2docker status 运行正在运行这在以前工作但在机器重启后，似乎没有任何效果。有什么想法吗？

主要问题是：

File "/Users/jwesonga/google-cloud-sdk/platform/google_appengine
       /lib/requests/requests/adapters.py", line 384, in send
    raise Timeout(e, request=request)
requests.exceptions.Timeout:   
(<requests.packages.urllib3.connection.VerifiedHTTPSConnection object 
at 0x10631c7d0>, 'Connection to 192.168.59.104 timed out. 
(connect timeout=60)')
ERROR: (gcloud.preview.app.run) DevAppSever failed with error code [1]

当您拥有代理时通常会出现这种情况，并在pip issue 1805

中进行了讨论

应该在pip1.6中修复，但为了以防万一，你可以尝试workaround of alexandrem

/opt/venvs/ironic/lib/python2.6/site-packages/pip/_vendor/requests
/adapters.patch.py /opt/venvs/ironic/lib/python2.6/site-packages
/pip/_vendor/requests/adapters.py
209c209
if True or not proxy in self.proxy_manager:
   ^^^^

基本上我只是在adapter.py第209行的条件中添加一个True来始终创建一个ProxyManager实例，从而跳过池管理器逻辑。

gcloud命令启用ah_host进程并创建应用程序的docker镜像并将其传递给Docker守护程序，在您的情况下，您的docker守护程序似乎没有响应请求。因此，要确保执行“sudo docker -d”以检查Docker守护程序是否在您的计算机上运行。另外，检查一下，您正确设置的证书路径和TLS_VERIFY的值是否为真。
