1. Tech Stack Used : Git Action, npm[Semantic Release], maven, react, springboot, docker, AWS[EC2, RDS, Route53, ECR] 2. Repository :          -Source repo : contains FrontEnd and BackEnd Code. Added release.yml so it could do tagging with Semantic Release.          -Infra repo : contains Git Action Workflow scripts. I added “Promotion.yml” script so triggered script could pull latest docker image and deploy it on RC server.  3. Work Flow :         -source repo has a workflow that releases tag in commits by semantic release         -once the release tag is created, it will kick off a promotion workflow in the infra repo         -workflow in infra repo(promotion.yml) will pull docker image and run it on pre-installed EC2         -pre-in...

  Introduction  This project was making CICD pipeline with Git Action, Docker, EC2, RDS, ECR, and Route53. I used my side project Jake (Social Media platform for international students) as source code. The flow of CI/CD pipeline goes like below. Source Repo contains Dockerfile and Docker-Compose.yml. It needs to run locally without any error. Infra Repo contains GitAction workflow codes. This triggers launching a temporary EC2 and fetch codes from source repo. It builds docker files and conducts smoke test. If smoke test succeeds, it pushes docker image to ECR, and it is deployed in EC2 as a QA Server. Route 53 directs IP address to domain name. The Issue  There were many issues and errors while building the CI/CD pipeline.  Source Repo Local test CORS Error : Connecting FrontEnd and BackEnd caused CORS error, which is not letting other origin use same address. To fix it, I used Reverse Proxy by Nginx, and added annotation in SpringBoot controller(@CrossOrigin)....
