- export MAVEN_HOME=/opt/apache-maven-3.6.3
- export PATH=$PATH:$MAVEN_HOME/bin

GIT

- yum install git -y 

JAVA

- yum install java -y

STEP 3 :

- curl -o kubectl https://amazon-eks.s3.us-west-2.amazonaws.com/1.20.4/2021-04-12/bin/linux/amd64/kubectl
- chmod +x ./kubectl
- mkdir -p $HOME/bin
- cp ./kubectl $HOME/bin/kubectl
- export PATH=$HOME/bin:$PATH
- echo'export PATH=$HOME/bin:$PATH' >> ~/.bashrc
- source $HOME/.bashrc
- kubectl version --short –client

STEP 4 :

- git clone https://github.com/tohidhanfi20/KUBERNETES-MINIKUBE-PROJECT

STEP 5 : IMPORTANT STEP

NOTE - Give your dockerhub ID in place of tohidaws

SERVICE 1 - Shopfront

    - cd shopfront/
    - mvn clean install -DskipTests
    - docker build -t tohidaws/shopfront:latest .
    - docker push tohidaws/shopfront:latest

SERVICE 2 - productcatalogue

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

SERVICE 3 - stockmanager

    - cd stockmanager/
    - mvn clean install -DskipTests
    - docker build -t tohidaws/stockmanager:latest .
    - docker push tohidaws/stockmanager:latest

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

STEP 7 :

 - kubectl get pods

STEP 8 :

Hit the below command to start the kubernetes dashboard in EC2

- /usr/local/bin/minikube dashboard

STEP 9 : IN NEW EC2 WINDOW

Open the EC2 in new window and set the PROXY

- kubectl proxy --address='0.0.0.0' --accept-hosts='^*$' 

STEP 10 :

Hit in browser to view the dashboard

- http://<EC2-IP>:8001/api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy/#/pod?namespace=default

STEP 11 :

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

EC2 LOGIN FOR SHOPFRONT

 - kubectl port-forward --address 0.0.0.0 svc/shopfront 8080:8010

EC2 LOGIN FOR productcatalogue

 - kubectl port-forward --address0.0.0.0 svc/productcatalogue 8090:8020

EC2 LOGIN FOR stockmanager

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

STEP 12 :

For productcatalogue

  - http://<EC2IP>:8090/products

For stockmanager

  - http://<EC2IP>:9008/stocks

STEP 13 :

ANALYZE THE DASHBOARD
