A Developer with access to his/her GitHub account Developer develops an app and pushes the code to GitHub (a distributed version source code control utility) 2. Jenkins setup Jenkins setup is required for DevOps viz. creating CI/CD pipeline/ Web Hooks. For current environment, Jenkins server is running on Google Cloud platform. 3. Dockerhub account A valid dockerhub account is required for container image registery. 4. A Kubernetes(k8s) Cluster (GKE) A k8s cluster is required for running the containers /container orchestration, scaling and overall container lifecycle management. I have used Google Kubernetes Engine (GKE) @ Google Cloud. It contains 1 load balancer and 3 nodes. Conditions K8s cluster, Jenkins, GitHub should be on  the same network (if private...
