MVP-Build a CI/CD Solution

[FeTodeschini]

Evaluate possible CI/CD solutions/architectures and implement the selected one

Jenkins was installed in a Docker container in the local Dev machine.

A subdomain was created for the test environment, which is now pointing to the only EC2 instance that exists so far. The dev environment will be the local machine, and the PROD server will be a new EC2 instance. Next steps:

• Create an EC2 image based on the current EC2
• Create the TERRAFORM scripts for deploying the PROD environment (launch the EC2 instance based on the test image, create all IAM roles and security groups and so on)
• Create a pipeline on Jenkins to deploy the infrastructure

Tasks Completed:

• A dedicated EC2 instance was created and configured for executing Jenkins in Dockers
• An extra EC2 instance and a new RDS MySQL were created for the Test environment. They were creating using Terraform (script added to this repository)
• A Jenkins pipeline was created for automatically deploying the nodejs application to the Test environment
• PM2 was configured via ecosystem.config.js to call the nodejs application (index.js) passing the correct environment variable NODE_ENV for the application to dinamically load the correct .env file (dev, test, prod)

Pending Items:

• Finish the nodejs pipeline by adding an approval step for deploying the application to PROD
• Create the pipeline for building and deploying the NextJs application 😅

The 2 pipelines below were created in Jenkins (running inside a Docker container in a dedicated EC2 instance) and successfully executed end to end, properly deploying and building the application in TEST and PROD:

• node: deploy and test the nodejs server application
• nextjs: build and deploy the NextJs application
