workshop2

Using the same basic Dockerized Django project from Workshop1 - with the objective to deploy the app to an AWS EC2 instance.

Overview:

• Use Workshop1 Django project
• Containerize app and associatied Postges DB using docker-compose.yml
• Build and Deploy Image to AWS EC2 Instance

Step-by-Step:

1. • Add new inbound rule for EC2 instance's security group

     -- Allow inbound requests for port 5433 for Postgres server

2. • Create ECR repo

     -- Go to 'Push Commands' and save the CLI command for authenticating Docker client to the the ECR registry

     -- Will be used at the end

3. • Setup RDS service
4. • Update ALLOWED_HOSTS with th EC2 DNS address in workshop2/app/nc_tutorials/settings.py

5. • Create docker-compose.yml file with the ECR repo's URI in the 'image' keys for the Django app and nginx app

     -- Also set web service's environment with the DB endpoint and EC2 DNS

6. • Create .env file for DB settings

     -- from decouple import config and apply to DATABASE settings in workshop2/app/nc_tutorias/settings.py

7. • Create GitHub repo, add remote origin, and push project to it
8. • Clone GitHub repo to EC2 instance via SSH session

9. • In SSH session, cd into project folder, compose dockerized project

     -- docker-compose up -d

10. • Run migrations for Django app's DB

      -- docker-compose exec web python manage.py makemigrations --noinput

      -- docker-compose exec web python manage.py migrate --noinput

* When I originally setup EC2 via the SSH session, I installed Docker Compose V1 (which requires hypen in docker-compose cli command)
  I am not yet proficient in linux commands/provisioning so I kept this version rather than installing V2

11. • Confirm container is running on the Elastic IP
12. • Use Insomnia to send a few POST requests and confirm containerized Django web app is accepting

13. • Push workshop2 image to the ECR

      -- Use the CLI Push Command that was saved after the ECR repo was created

      -- docker-compose push

      -- Confirm the Django and NGINX images are now inside the ECR repo via AWS console
