(gcloud.run.deploy) Cloud Run 错误：容器无法启动。启动失败，然后监听端口

Question

使用gcloud builds submit --tag gcr.io/projectname/testserver 成功部署容器然后尝试运行gcloud run deploy --image gcr.io/projectname/testserver --platform managed 后，我看到此错误：

$ gcloud run deploy --image gcr.io/projectname/testserver --platform managed
Please specify a region:

Service name (testserver):

我有一个非常简单的项目，全部在根文件夹中：

// Dockerfile
FROM node:12-slim

# Create app folder
WORKDIR /usr/src/app

# Install app deps. Copy the lock file
COPY package*.json ./
RUN npm install

COPY . ./
CMD ["node", "testServer.js"]

// testServer.js
const Koa = require("koa");
const koa = new Koa();

koa.get('/', async ctx => {
  ctx.body = "Koa server running"
});

const port = process.env.PORT || 8080;

koa.listen(port);

有人知道这是什么原因吗？从昨天开始一直在尝试解决它，现在即使是这个最小的项目，它似乎也有问题。

Answer 1

我收到了带有您的代码的TypeError: app.get is not a function。看起来这种语法已经过时了。用koa-router 重写并且工作得很好。

无论如何，在部署之前尝试使用docker run 在本地测试您的代码。 您还可以在控制台->日志记录->云运行修订->修订_id中找到更精确的错误消息

Answer 2

这里同样的错误。我解决了增加timeout的问题。
