(gcloud.run.deploy) Cloud Run error: Container failed to start. Failed to start and then listen on the port

Question

After successfully deploying a container using gcloud builds submit --tag gcr.io/projectname/testserver and then attempting to run gcloud run deploy --image gcr.io/projectname/testserver --platform managed I see this error:

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

Service name (testserver):  
Allow unauthenticated invocations to [testserver] (y/N)?  y

I have a very simple project, all in the root folder:

// 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);

Anyone know what's causing this? Been trying to solve it since yesterday and now even with this minimal project it seems to be having issues.

What if any errors are being logged from the startup of the container? Can you collect all your artifacts and put them in a temporary GitHub repo and post the link. Maybe some kind soul might attempt a recreate? — Kolban

I received TypeError: app.get is not a function with your code. Looks like this syntax is obsolete. Rewrote with koa-router and worked just fine.

Anyway try to test your code locally with docker run before deploying. And also you can find more precise error messages during deployment in console-> logging-> cloud run revision-> revision_id
