  • Basic knowledge of Docker, and AWS services.
  • An AWS account with necessary permissions.

Steps

Step 1: EC2 Setup

  • Launch an Ubuntu (t2.micro) instance in your favourite region (eg. region us-west-2).
  • SSH into the instance from your local machine.

Step 2: Clone the Code:

  • Update all the packages and then clone the code.
  • Clone your application's code repository onto the EC2 instance:
git clone https://github.com/Vishvanath-Patil/Three-Tier-Application-Deployment-Project.git

Step 3: IAM Configuration

  • Create a user eks-admin with AdministratorAccess.
  • Generate Security Credentials: Access Key and Secret Access Key.

Step 4: Install AWS CLI v2

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

Step 5: Install Docker

sudo apt-get update
sudo apt install docker.io
docker ps
sudo chown $USER /var/run/docker.sock

Step 6: Install kubectl

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

Step 7: 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

Step 8: 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

Note :

make sure replace by your region and clustername

Step 9: Create ECR Repository

Prerequisites to Push docker image to ECR Repo is aws configure this has done in Step.4

Step 9.1 : Search ECR and Click on Get Started

image

Step 9.2 : Choose Repository type Public and fill Repository Name worokshop/three-tier-backend then Click on Create Repository

image

Step 9.3 : Then Open worokshop/three-tier-backend and click on View Push Commands

image

Step 9.4 : Click on View Push Commands

image

Step 9.5 : Use following Commands to Build Docker Image and Push to ECR Repository

image

###Note :- should RUN these commands inside Dockerfile directory

Step 10: Run Manifests

kubectl create namespace workshop
kubectl config set-context --current --namespace workshop
kubectl apply -f .
kubectl delete -f .

Step 11: Install AWS Load Balancer

curl -O https://raw.githubusercontent.com/kubernetes-sigs/aws-load-balancer-controller/v2.5.4/docs/install/iam_policy.json
aws iam create-policy --policy-name AWSLoadBalancerControllerIAMPolicy --policy-document file:https://iam_policy.json
eksctl utils associate-iam-oidc-provider --region=us-west-2 --cluster=three-tier-cluster --approve
eksctl create iamserviceaccount --cluster=three-tier-cluster --namespace=kube-system --name=aws-load-balancer-controller --role-name AmazonEKSLoadBalancerControllerRole --attach-policy-arn=arn:aws:iam::626072240565:policy/AWSLoadBalancerControllerIAMPolicy --approve --region=us-west-2

Note :

Replace AWS Account ID (626072240565), AmazonEKSLoadBalancerControllerRole, AWSLoadBalancerControllerIAMPolicy, and region

Step 12: Deploy AWS Load Balancer Controller

sudo snap install helm --classic
helm repo add eks https://aws.github.io/eks-charts
helm repo update eks
helm install aws-load-balancer-controller eks/aws-load-balancer-controller -n kube-system --set clusterName=my-cluster --set serviceAccount.create=false --set serviceAccount.name=aws-load-balancer-controller
kubectl get deployment -n kube-system aws-load-balancer-controller
kubectl apply -f full_stack_lb.yaml

Cleanup

  • To delete the EKS cluster:
eksctl delete cluster --name three-tier-cluster --region us-west-2
