google-cloud-platform - (gcloud.run.deploy)Cloud Run错误: Container failed to start.无法启动然后监听端口

Question

使用gcloud builds Submit --tag gcr.io/projectname/testserver成功部署容器后，然后尝试运行gcloud run deploy --image gcr.io/projectname/testserver --platform Managed 我看到这个错误:

$ gcloud run deploy --image gcr.io/projectname/testserver --platform managed

我有一个非常简单的项目，全部位于根文件夹中:

// 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);

有谁知道这是什么原因造成的吗？从昨天开始就一直在尝试解决这个问题，现在即使是这个最小的项目，它似乎也存在问题。

我在您的代码中收到了TypeError: app.get is not a function。看起来这个语法已经过时了。重写为koa-router并且工作得很好。

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