部署失败，在 digitalocean app-engine django app 的控制台上没有提示任何错误

Question

We have 2 apps that are running with similar settings, now we are trying to deploy another app but this time it's failing without telling any error in app engine. Python django app starts and then suddenly app engine stops deployment. How to find reason behind that?

Answer 1

I think you missed assigning the correct port for that specific app. By default DO sets port 8080. And according to logs, it's listening to port 5000.

So probably that could be the mistake. You can update it from the YAML file in the digital ocean app settings. Or click the edit icon corresponding to the resource to configure details such as HTTP routes or the HTTP port.
