INSTALL EKS SETUP ############################################################# Step1: Take EC2 Instance with t2.MEDIUM instance type Step2: Create IAM Role with Admin policy for eks-cluster and attach to ec2-instance Step3: Install kubectl
curl -o kubectl https://amazon-eks.s3-us-west-2.amazonaws.com/1.14.6/2019-08-22/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 $HOME/.bashrc kubectl version --short --client
Step4: Install eksctl: curl --silent --location "https://github.com/weaveworks/eksctl/releases/latest/download/eksctl_$(uname -s)_amd64.tar.gz" | tar xz -C /tmp sudo mv /tmp/eksctl /usr/bin eksctl version
Step5: MASTER Cluster creation:
eksctl create cluster --name=eksdemo
--region=us-west-1
--zones=us-west-1b,us-west-1c
--without-nodegroup
Step6: Add Iam-Oidc-Providers:
eksctl utils associate-iam-oidc-provider
--region us-west-1
--cluster eksdemo
--approve
Allowing the service to connect with EKS
Step7: WORKER NODE Create node-group:
eksctl create nodegroup --cluster=eksdemo
--region=us-west-1
--name=eksdemo-ng-public
--node-type=t2.medium
--nodes=2
--nodes-min=2
--nodes-max=4
--node-volume-size=10
--ssh-access
--ssh-public-key=Praveen-test
--managed
--asg-access
--external-dns-access
--full-ecr-access
--appmesh-access
--alb-ingress-access
//eksctl delete nodegroup --cluster=eksdemo --region=us-east-1 --name=eksdemo-ng-public
//eksctl delete cluster --name=eksdemo --region=us-west-1

HANDSON
Deploying Java Applications with Docker and Kubernetes
-
Build each project ->> mvn clean install -DskipTests
-
Create docker hub account
-
Build the image in local -> docker build -t praveensingam1994/shopfront:latest .
docker build -t praveensingam1994/productcatalogue:latest .
docker build -t praveensingam1994/stockmanager:latest .
- Push the image to your docker hub -> docker push praveensingam1994/shopfront:latest
docker push praveensingam1994/productcatalogue:latest
docker push praveensingam1994/stockmanager:latest
- Go to kubernetes folder and create the pods ->
kubectl apply -f shopfront-service.yaml
kubectl apply -f productcatalogue-service.yaml
kubectl apply -f stockmanager-service.yaml
- minikube service servicename ->
minikube service shopfront minikube service productcatalogue minikube service stockmanager
- Hit the url in browser ->
ORDER TO BUILD AND DEPLOY
shopfront -> productcatalogue -> stockmanager
Endpoint for product --> /products Endpoint for stock --> /stocks
