railway_django_stack

Full Django/Postgres stack with Celery tasks and Redis as cache/queue.

Overview

Deploy a "complete" Django setup - DB, caching and background tasks with Celery are all set up and ready to go.

Check out the full readme and brief on GitHub: https://github.com/Antvirf/railway_django_stack

Deploying the template

1. In the deployment screen, you will need to configure a DJANGO_SECRET_KEY. You can use the below snippet to do that or otherwise generate your own.

   Snippet to create secret

   This assumes your default python installation has Django installed.

   python -c 'from django.core.management.utils import get_random_secret_key; print(get_random_secret_key())'

2. Once the containers have been deployed, please take the following steps to delete public proxy addresses, as you will not need to access the private services directly:

   • Go to the Postgres service > Settings > Networking, delete the proxy
   • Go to the Redis service > Settings > Networking, delete the proxy

Resources

This template deploys:

• 1 service running Django
• 1 service running Celery (same as container #1 but with different startup command)
• 1 service running Redis
• 1 service running Postgres

You can test the setup locally with docker compose:

git clone https://github.com/Antvirf/railway_django_stack
cd railway_django_stack
docker-compose up

Service diagram

Warning Please check the instructions above on deploying the template. By default, Railway creates publicly available proxies for your Postgres and Redis services - make sure to delete them. Should you ever need direct access, creating the proxies is just a few clicks.
