Create EKS cluster on AWS using eksctl

Pre-requisites:

1. Ubuntu Server
2. Free tier AWS account

Note: EKS service not come in the free tier service, so make sure the delete all the resources when your work is done

Step 1: Install Below Dependancies:

1. Install AWS CLI:

curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
sudo apt install unzip
unzip awscliv2.zip
sudo ./aws/install
aws configure

2. 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

3. 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 2: Create EKS Cluster:

eksctl create cluster --name=eks-cluster \
                      --region=ap-south-1 \
                      --zones=ap-south-1a,ap-south-1b \
                      --without-nodegroup

Step 3: Associate IAM OIDC Provider:

eksctl utils associate-iam-oidc-provider \
    --region ap-south-1 \
    --cluster eks-cluster \
    --approve

Step 4: Create EC2 Key-pair

1. Create the new ec2 key pair: eks-db-key

This keypair we will use it when creating the EKS NodeGroup. This key will help you to login the AWS EKS worker nodes

Step 5: Create EKS Worker Nodes:

Create EKS Worker Nodes in the public Group:

# Create Public Node Group   
eksctl create nodegroup --cluster=eks-cluster \
                       --region=ap-south-1 \
                       --name=eks-cluster-ng-public1 \
                       --node-type=t3.medium \
                       --nodes=2 \
                       --nodes-min=2 \
                       --nodes-max=4 \
                       --node-volume-size=20 \
                       --ssh-access \
                       --ssh-public-key=eks-db-key \
                       --managed \
                       --asg-access \
                       --external-dns-access \
                       --full-ecr-access \
                       --appmesh-access \
                       --alb-ingress-access 

Create EKS Cluster in Private NodeGroup:

# Create EKS NodeGroup in VPC Private Subnets (Section-07-01)
eksctl create nodegroup --cluster=eks-cluster \
                        --region=ap-south-1 \
                        --name=eks-cluster-ng-private1 \
                        --node-type=t3.medium \
                        --nodes-min=2 \
                        --nodes-max=4 \
                        --node-volume-size=20 \
                        --ssh-access \
                        --ssh-public-key=eks-db-key \
                        --managed \
                        --asg-access \
                        --external-dns-access \
                        --full-ecr-access \
                        --appmesh-access \
                        --alb-ingress-access \
                        --node-private-networking    

Step 06: Delete AWS EKS Cluster:

1. Delete the Nodegroup

eksctl get clusters
eksctl get nodegroup --cluster=eks-cluster
eksctl delete nodegroup --cluster=eks-cluster --name=eks-cluster-ng-public1

2. Delete Cluster:

eksctl delete cluster eks-cluster
