Sample Java Web App in Spring Boot framework with Containerization (Plus Kubernetes NGINX Ingress Controller Deployment)

Readme update 1.1

Highlevel Diagram To Illustrate What We Are Going To Create (Red Circle)

In this sample, I'm using my Private Registry (Azure Container Registry - ACR) to deploy any PODs in K8S.

Create New Dev Namesapce in K8S

kubectl apply -f namespace-dev.json

Create NGINX Ingress Controller Pods and Necessary Components in K8S

kubectl apply -f mandatory.yaml

Deploy 1st Load Balance Sample App (Apple) in K8S

kubectl apply -f apple.yaml

Deploy 2nd Load Balance Sample App (Banana) in K8S

kubectl apply -f banana.yaml

Create NGINX Ingress Controller Service in K8S

kubectl apply -f ingress-nginx.yaml

Configure NGINX Ingress Controller Rules in K8S

kubectl apply -f ingress.yaml

Check NGINX Ingress Controller Service IP (Internal IP) in K8S

kubectl get services ingress-nginx-apple-banana

Test Service

http://INTERNAL_IP/apple
http://INTERNAL_IP/banana

Build 1st Java Spring Boot Micro-service (Apple)

/sb-web-apple/mvn package

Build 2nd Java Spring Boot Micro-service (Banana)

/sb-web-banana/mvn package

Create Secret Object In K8S To Store Private Registry (Azure Container Registry - ACR) Login

kubectl create secret docker-registry qooacr01 --docker-server=qooacr01.azurecr.io --docker-username=LOLLOL --docker-password=LOLLOLOLOLOLOLOL --docker-email=easonlai@msn.com

Docker Build 1st & 2nd Java Spring Boot Micro-service And Push to Private Registry (Azure Container Registry - ACR)

docker build -t easonlai/sb-web-apple .
docker build -t easonlai/sb-web-banana .
docker tag easonlai/sb-web-apple qooacr01.azurecr.io/sb-web-apple
docker tag easonlai/sb-web-banana qooacr01.azurecr.io/sb-web-banana
docker push qooacr01.azurecr.io/sb-web-apple
docker push qooacr01.azurecr.io/sb-web-banana

Pull Image and Push to Private Registry (Azure Container Registry - ACR)

docker tag quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.24.1 qooacr01.azurecr.io/nginx-ingress-controller:0.24.1
docker push qooacr01.azurecr.io/nginx-ingress-controller:0.24.1
