Hi, can you show me your application logs?

Hello. Thanks for your response.

There is no application logs since the first deployment fails. After your message, I did following

  • deleted the app and cluster
  • recreated the cluster, and app
  • deployed.
  • logs below

Your app seems to fail to start and no log is streamed on the output. Did you turn on your app logger? (Did you set a potential environment variable to turn it on?) Can you check please?

There’s a docker-compose.yml as well along with the Dockerfile. The docker-compose.yml is supposed to start the application. I believe that’s why the app is not starting. I will update the codebase to include start commands in Dockerfile.


You probably must add a CMD command at the end of your Dockerfile

I can confirm that after I added CMD to Dockerfile the deployment went through. I have other problems, but I will raise another topic for that.
