K8S, Jenkins and StickerStore app deployment

The purpose of this challenge is to build and deploy a application to a Kubernetes cluster

In this challenge we will:

  1. Install a Jenkins from Helm Chart
  2. Build the images from GitHub repo.
  3. Push the images to Docker Hub.
  4. Execute YAML deployment files in the K8S cluster from the Jenkins pipeline.
