Implemented a DevOps lifecycle such that all the requirements are implemented without any change in the Docker containers in the testing environment. CodeBuild is triggered once the commits are made in the master branch. The code is containerized with the help of the Dockerfile. The Dockerfile is built every time there is a push to GitHub. Used Kubernetes cluster and the containerized code from Docker Hub is deployed with 2 replicas. Created a NodePort service and configure port 30008. Created a Jenkins pipeline script to accomplish the above task.
