FATAL: database "engine" does not exist

[haharay]

hello,
when running the "docker-compose run web python manage.py migrate" for local development, i get:
Starting app_postgres_1 ... done
Traceback (most recent call last):
File "/usr/local/lib/python3.6/site-packages/django/db/backends/base/base.py", line 216, in ensure_connection

conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
psycopg2.OperationalError: FATAL: database "engine" does not exist

The above exception was the direct cause of the following exception:

django.db.utils.OperationalError: FATAL: database "engine" does not exist

P.S.
However, "docker-compose run web pytest":
Starting app_postgres_1 ... done
.....
======================== 11 passed, 4 warnings in 9.61s =========================

P.S.
When i Open an interactive shell in engine docker container by "docker-compose run engine bash", then Create super user account by "python manage.py createsuperuser", i get similar error.
I try "python manage.py createdb", getting the result: Unknown command: 'createdb' .

Thanks!

Hello,

I am having this same issue. I first tried running

"docker-compose run engine python manage.py migrate"

and got

ERROR: No such service: engine

Then, I tried "docker-compose run web python manage.py migrate" and got the same output as haharay.

Thanks!

Hello !

Checking to see if there have been any updates for this issue?

Cheers!

You need to create the "engine" db, access the postgres container
sudo docker exec -it app_postgres_1 bash
inside the container
psql -U postgres
to access postgres db
then just create the "engine" db
CREATE DATABASE engine; \q;
get back to the local machine, re-run your command line and you'll see migrations in action.

hope it can be useful for you.
