3. Deploying apps to Kubernetes (using kubectl)
4. Deploying apps to Kubernetes (using Helm3)

Minikube - Setup & Notes

Important: Complete the Minikube Setup before starting the tutorial

Tutorial

Step 1

Step 2

Build a simple (backend) Java application. See app-showcase-backend-java/README

Step 3

Deploy the (frontend) and (backend) apps to Kubernetes (Minikube) using kubectl. See kubectl-release-manager/README. It is important you understand the Kubernetes resource kinds, YAML specification & kubectl commands before moving to helm
