Canary Deployment NodejsApp

Pre-requisites:

- Install GIT
- EKS Cluster
- Install ALB-Ingress-Controller
- Install Istio
- Request a Cerficate using Certificate Manager
- Create Hosted Zone with our Domain Name
- External DNS Setup

EKS Cluster Setup:

EKS Cluster Setup

ALB Ingress Controller Setup:

ALB Ingress Controller

Istio Setup:

Istio

Create Hosted Zone with our Domain Name

Request a Cerficate using Certificate Manager

External DNS Setup:

External DNS

Install GIT:

yum install git -y

Install Docker:

yum install docker -y
service docker start

Clone code from github:

git clone https://github.com/cloudtechmasters/Canary-Deployment-NodejsApp.git
cd Canary-Deployment-NodejsApp

Build Maven Artifact:

npm install

Build Docker image for Springboot Application

docker build -t cloudtechmasters/node-web-app:v1 .

Docker login

docker login

Push docker image to dockerhub

docker push cloudtechmasters/node-web-app:v1

Upgrading for nodejs Application:

Edit our our application and Build docker image with new tag:

docker build -t cloudtechmasters/node-web-app:v2 .

Push Docker image to docker hub with tag v2:

docker push cloudtechmasters/node-web-app:v2

Deploy nodejs Application using below commands:

kubectl apply -f deployment-v1.yml
kubectl apply -f deployment-v2.yml
kubectl apply -f service.yml

Check Deployments, Pods and Services:

kubectl get deploy
kubectl get pods
kubectl get svc

Create an Istio Gateway, VirtualService and default destination rules

kubectl apply -f istio-rules.yml

Check Istio Gateway

kubectl get gateway -n istio-system
kubectl get virtualservice -n istio-system
kubectl get destinationRule -n istio-system

Run ingress for checking output with DNS name

kubectl apply -f ingress.yml

Check Load Balancer of ALB ingress controller attached to ingress or not

kubectl get ingress

Two records creates automatically in Route53 because of External DNS

Go to UI and check our external dns, which showing output application with HTTPS

Check application number of times you can get to know how our applicaiton will work based on Destination rules:
