Error deploying a function from vscode cloud run extension

Question

I am new to cloud computing and I'm trying to use google cloud to run some python codes. I use the vscode extension Cloud Run to deploy one function and run it on the cloud but I am getting the following error:

Could not create or update Cloud Run service scraping, Container Healthcheck failed. Revision 'scraping-00002-puv' is not ready and cannot serve traffic. The user-provided container failed to start and listen on the port defined provided by the PORT=8080 environment variable. Logs for this revision might contain more information.

Here are the steps I followed:

• I created an application folder with my.py codes (scraping_functions.py) and the automatic launch.json that contains the following configurations:

{
  "configurations": [
    {
      "name": "Deploy Cloud Function",
      "type": "cloudcode.cloudfunctions",
      "request": "launch",
      "functionName": "scraping",
      "gen": "GEN_2",
      "revision": "scraping-00001-biy",
      "entryPoint": "hello_get",
      "testInput": "",
      "region": "europe-west1",
      "runtime": "python310"
    },
    {
      "name": "Cloud Run: Run/Debug Locally",
      "type": "cloudcode.cloudrun",
      "request": "launch",
      "build": {
        "docker": {
          "path": "Dockerfile"
        }
      },
      "image": "scraping",
      "service": {
        "name": "scraping",
        "containerPort": 8080,
        "resources": {
          "limits": {
            "memory": "256Mi"
          }
        }
      },
      "target": {
        "minikube": {}
      },
      "watch": true,
      "internalConsoleOptions": "neverOpen"
    },
    {
      "name": "Python: Current File",
      "type": "python",
      "request": "launch",
      "program": "${file}",
      "console": "integratedTerminal",
      "justMyCode": true
    },
    {
      "name": "Deploy Cloud Function",
      "type": "cloudcode.cloudfunctions",
      "request": "launch",
      "functionName": "function-scrape",
      "gen": "GEN_2",
      "entryPoint": "hello_get",
      "revision": "function-scrape-00003-vuh",
      "testInput": "",
      "region": "europe-west1",
      "runtime": "python310"
    },
    {
      "name": "Docker: Python - General",
      "type": "docker",
      "request": "launch",
      "preLaunchTask": "docker-run: debug",
      "python": {
        "pathMappings": [
          {
            "localRoot": "${workspaceFolder}",
            "remoteRoot": "/app"
          }
        ],
        "projectType": "general"
      }
    }
  ]
}

-I also have a dockerfile that was generated automatically from the vscode extension. -On the cloud run extension, I go to Cloud Functions and click deploy function. I also tried to run and debug but the same error appears...

• The log file indicated in the error message does not seem to contain much more interesting information so I am not sure what can be causing the error.

Answer 1

The most common cause of this error is the container not listening for incoming HTTP requests on the port that is defined by Cloud Run and provided in the $PORT environment variable. This is a requirement for Cloud Run.

You can refer to this Documentation , which lists a series of steps to follow when encountering this error to fix the issue.

I have found this issue tracker raised for a similar issue which is still open. you can report there.

You can also check with these thread1 and thread2 which may help you.
