如何修复Docker Craft Cloud Run deployment中的“CloudSQL连接失败:超过上下文截止日期”

Question

最近，当我尝试升级docker文件的php版本时，我开始收到CloudSQL连接错误。

这开始于今天早上‘2019年8月8日’。起初，我以为我升级的php版本与unix socket或类似版本不兼容，所以我降级了。这不管用。所以我继续走回头路，回到昨天的版本(同样的env和docker sha)这个问题仍然存在，然后我回到了一个稳定的docker版本，我知道它正在做一个姊妹云运行服务。没有骰子。

简而言之，我试图更新的唯一一件事就是docker文件及其构建方式。(尝试启用opcache，我发现它在本地的工作很神奇，可以加速请求)旧的

我为张贴整个文件道歉。

预期的和实际的结果已经解释过了。

我发现的一些观察结果是，超时恰好是10秒，如果这与什么有关的话。

任何帮助都将不胜感激。

提前谢谢你。

检查并确保您的云SQL实例已开启公网IP连接。未开启时，云SQL proxy将无法正常工作。
