STEP 5 – IMPORTANT STEP

[ 3 SERVICES IN PROJECT ]
SERVICE1 [ Give your dockerhub ID in place of dharm1996 ]
cd shopfront/
mvn clean install -DskipTests

docker build -t dharm1996/shopfront:latest .

docker push dharm1996/shopfront:latest

SERVICE2 [ Give your dockerhub ID in place of dharm1996 ]

cd productcatalogue/
mvn clean install -DskipTests
docker build -t dharm1996/productcatalogue:latest . docker push dharm1996/productcatalogue:latest

SERVICE3 [ Give your dockerhub ID in place of dharm1996 ]
cd stockmanager/
mvn clean install -DskipTests (to convert your application into jar) docker build -t dharm1996/stockmanager:latest . docker push dharm1996/stockmanager:latest

First Login into dockerhub using command docker login then enter username and password

docker login

Docker hub Public Repository

STEP 6 - GO TO KUBERNETES FOLDER IN SAME
PROJECT
cd kubernetes
kubectl apply -f shopfront-service.yaml kubectl apply -f productcatalogue-service.yaml kubectl apply -f stockmanager-service.yaml

you can check the pods and services

STEP 7 – Hit the below command to start the kubernetes dashboard in EC2
/usr/local/bin/minikube dashboard

STEP 8 [ IN NEW EC2 WINDOW ] - Open the EC2 in new window and set the PROXY
kubectl proxy --address='0.0.0.0' --accept-hosts='^*$'

STEP 9 - Hit in browser to view the dashboard
http://<EC2-IP>:8001/api/v1/namespaces/kubernetes-da
shboard/services/http:kubernetes-dashboard:/proxy/#/po
d?namespace=defaultKub

Kubernetes Dashboard

STEP 10 – Hit the below command for each service in
different console of EC2

[ EC2 LOGIN FIRST ]
kubectl port-forward --address 0.0.0.0 svc/shopfront
8080:8010
[EC2 LOGIN FIRST]
kubectl port-forward --address 0.0.0.0 svc/productcatalogue
8090:8020
[ EC2 LOGIN FIRST ]

kubectl port-forward --address 0.0.0.0 svc/stockmanager
9008:8030
