Elastic Django!

A little app to demonstrate the basic process for launching a Django app on AWS Elastic Beanstalk. This is NOT production-ready and uses a sqlite3 database on an ephemeral EC2 instance which will be lost on every application update! to make this production ready you must use an external database among many other things. This just demonstrates the basic process and starter config.

Basic process:

1. Create venv, activate and start django project/apps
2. Install requirements (including awsebcli) and create requirements.txt
3. Create .ebextensions/django.config (Handles launching WSGI app)
4. Create Elastic Beanstalk repo: eb init -p python-3.6 [repo-name]
5. Set up SSH for EC2: eb init again or eb ssh --setup
6. Create your EB env: eb create [env-name]
7. Get CNAME with eb status and add it to ALLOWED_HOSTS in settings.py
8. Optionally, configure git with eb use [env-name] while checked out on the branch you want to tie to that environment
9. Update settings with STATIC_ROOT = /static/
10. Configure .ebextensions/db-migrate.config (Handles initial DB migrations and static files)
11. Deploy with eb deploy
12. Navigate to CNAME from step 7 and you should see your default Django successful launch page!
13. Don't forget to terminate your EC2 instance to prevent pointless charges when you're done experimenting! eb terminate [env-name]
14. If you want to recreate it again, just eb create [env-name] and pick up with step 7 to update settings accordingly
