Twoge CICD by Matt

Twoge is a social media platform dedicated solely to tweets about Dodge. This application is built using Flask, SQLAlchemy, and PostgreSQL (see the rest of the original Twoge readme.md at https://github.com/chandradeoarya/twoge)...

App launch and CICD Implementation

Before CICD, the application is brought up and running via:

1. Terraform technology to create the AWS RDS instance (not included in this repo, but see Other Things topic below for more information on how to set that up)
2. Dockerfile
3. Elastic Beanstalk CLI commands:
   • eb init
   • eb create twoge-app-server --single
   • eb setenv SQLALCHEMY_DATABASE_URI=postgresql://user:password@db-host:5432/twogedbtf
   • eb deploy
4. Now the app is running and it is CICD's time to shine:
   • Choose a branch for updates to be applied to image and infrastructure when pushed to repository
   • Define jobs for unit testing (ideally, but unit tests are not included in this example), image updates, and application/infrastructure updates

Other things

The creation of the AWS RDS instance was done using Terraform code as outlined in a few examples, changing and adding as necessary:

• terraform docs are always helpful:
  • https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/db_instance
  • https://registry.terraform.io/modules/terraform-aws-modules/rds/aws/latest
