CI/CD with Atlantis
Armed with the knowledge about tooling and principles around CI/CD (both delivery and deployment), we will create a CI/CD pipeline with the use of Git and the open source tool Atlantis. We will automatically test and deploy changes to our AWS infrastructure with it and do basic testing along the way.
