Deploy Django app on GCP. Got "ERROR: (gcloud.app.deploy) Error Response: [9] Application startup error:"

[satendrapratap]

I am trying to deploy my django backend rest apis on GCP by following the google tutorial at https://cloud.google.com/python/django/flexible-environment

I was able to deploy sample app successfully but when I am trying to deploy my django app then I get below errors:

Updating service [default] (this may take several minutes)...failed. ERROR: (gcloud.app.deploy) Error Response: [9] Application startup error: [2018-04-03 13:01:35 +0000] [1] [INFO] Starting gunicorn 19.7.1 [2018-04-03 13:01:35 +0000] [1] [INFO] Listening at: http://0.0.0.0:8080 (1) [2018-04-03 13:01:35 +0000] [1] [INFO] Using worker: sync [2018-04-03 13:01:35 +0000] [7] [INFO] Booting worker with pid: 7 [2018-04-03 13:01:35 +0000] [1] [INFO] Shutting down: Master [2018-04-03 13:01:35 +0000] [1] [INFO] Reason: Worker failed to boot.

In build history, it shows success: Build information Status

In GCP logs also it shows no error but "Worker failed to boot": A 2018/04/03 13:01:32 Ready for new connections A 2018/04/03 13:01:33 Listening on /cloudsql/bcbackend-200008:europe- west3:bc-mysql-instance for bcbackend-200008:europe-west3:bc-mysql-instance A [2018-04-03 13:01:35 +0000] [1] [INFO] Starting gunicorn 19.7.1 A [2018-04-03 13:01:35 +0000] [1] [INFO] Listening at: http://0.0.0.0:8080 (1) A [2018-04-03 13:01:35 +0000] [1] [INFO] Using worker: sync A [2018-04-03 13:01:35 +0000] [7] [INFO] Booting worker with pid: 7 A [2018-04-03 13:01:35 +0000] [1] [INFO] Shutting down: Master A [2018-04-03 13:01:35 +0000] [1] [INFO] Reason: Worker failed to boot.

Tried running it with "--verbosity=debug" option and below is the log:

Hi @satendrapratap ! Can you run your Django app locally without a problem?

It's worth noting this repo is not maintained (and never really was), and that the relevant sample is in python-docs-samples, so at least this issue should have been there, it's unclear which code was being run. This repo should be archived.
