In this Project I am Using Docker,AWS ECR Kubernetes, Ingress, AWS ALB

Firstly i want to clone any three-tier application from github and make it containerise with Docker

git clone https://github.com/SarthakTyagiji/TWSThreeTierAppChallenge.git

Now go to Application>frontend>here make a Dockerfile

FROM node:14
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .
CMD [ "npm", "start" ]

Build it and run it

docker build -t sarthak_front .
docker run -d -p 3000:3000 sarthak_front
#React application by default run on Port 3000

now check it's run or not go to browser

localhost:3000
#if it's running perfectly then kill that container and rm it 
docker kill container id
docker rm container id 
cd ..

cd backend and make a docker file in it

FROM node:14
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .
CMD ["node", "index.js"]

same build it run it

docker build -t sarthak_back .
docker run -d -p 3500:3500 sarthak_front

Now it's time to push it to aws ecr so for that you need

AWS cli in your pc then install it first go to home dir cd ..

Install AWS CLI 2

curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
sudo apt install unzip
unzip awscliv2.zip
sudo ./aws/install -i /usr/local/aws-cli -b /usr/local/bin --update
aws configure

Now make a iam user and give secure key and access key paste it here

Now in AWS ECR make a repo and push it here

front end and backend

Install kubectl

Go to home and install kubernetes controller

curl -o kubectl https://amazon-eks.s3.us-west-2.amazonaws.com/1.19.6/2021-01-05/bin/linux/amd64/kubectl
chmod +x ./kubectl
sudo mv ./kubectl /usr/local/bin
kubectl version --short --client

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/local/bin
eksctl version

Setup EKS Cluster

eksctl create cluster --name three-tier-cluster --region us-west-2 --node-type t2.medium --nodes-min 2 --nodes-max 2
aws eks update-kubeconfig --region us-west-2 --name three-tier-cluster
kubectl get nodes

It take 15-20 min for making a cluster by Cloud Formation
