在本地运行 ESP 时出现 Cloud Endpoints 错误

Question

我正在尝试在我的 Mac 上本地运行 Cloud Endpoints ESP 容器，并遵循 https://cloud.google.com/endpoints/docs/openapi/running-esp-localdev 的文档。

我可以使用 openapi yaml 文件将端点配置部署到 GCP。但是有些 ESP 容器无法从服务管理 API 获取服务定义。

我查看了 ESP 容器日志，它出现以下错误。我错过了什么吗？

Answer 1

Operation timed out 错误意味着您的 ESP 容器可能存在网络问题。尝试运行：

$ docker run byrnedo/alpine-curl curl -sI servicemanagement.googleapis.com

如果您看到HTTP/1.1 404 Not Found，那么您可以消除 docker 网络设置的任何问题；否则请尝试遵循https://success.docker.com/article/troubleshooting-container-networking 的故障排除指南。
