Hi I am having issues running migrations on postgres db container from django.
Here is my docker-compose file
web:
restart: always
build: ./web
expose:
- "8000"
links:
- postgres:postgres
volumes:
- /usr/src/app
- /usr/src/app/static
env_file:
- ./.env
environment:
- DEBUG=1
command: /usr/local/bin/gunicorn mysite.wsgi:application -w 2 -b :8000
nginx:
restart: always
build: ./nginx/
ports:
- "80:80"
volumes:
- /www/static
volumes_from:
- web
links:
- web:web
postgres:
restart: always
build: ./postgres
env_file: .env
ports:
- "5432:5432"
volumes:
- pgdata:/var/lib/postgresql/data/
The directory structure is below. 
The .env file defines the Postgres DB , user name and password
DB_NAME=test
DB_USER=test
DB_PASS=test!
DB_SERVICE=postgres
DB_PORT=5432
POSTGRES_USER=test
POSTGRES_DB=test
POSTGRES_PASSWORD=test!
When I run docker-compose build and docker-compose up -d nginx, postgres and web containers start. The postgres startup (default) creates the db, user and password. The django startup container installs requirements.txt and starts the django server (everything looks good).
On running makemigrations
docker-compose run web /usr/local/bin/python manage.py makemigrations polls
I get the following output
Migrations for 'polls':
0001_initial.py:
- Create model Choice
- Create model Question
- Add field question to choice
But when I run
docker-compose run web /usr/local/bin/python manage.py showmigrations polls
the output is.
polls
(no migrations)
on running
docker-compose run web /usr/local/bin/python manage.py migrate --fake polls
the output I see
Operations to perform:
Apply all migrations: (none)
Running migrations:
No migrations to apply.
Your models have changes that are not yet reflected in a migration, and so won't be applied.
Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.
The tables are not created in postgres. What am I doing wrong ? Sorry for the long post but I wanted to put all the details here.
settings.py?
