Create EKS CLUSTER

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

The command you provided is used to associate an IAM OIDC identity provider for an Amazon EKS cluster. It allows the Kubernetes API server to authenticate service accounts using IAM roles.

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

This command creates a managed node group named "node2" within the Amazon EKS cluster "EKS-1" in the Asia Pacific (Mumbai) region. It consists of 3 nodes with a minimum of 2 and a maximum of 4, using t3.medium instances with 20GB disk volumes. SSH access is enabled with the "DevOps" public key. The group has permissions for Auto Scaling, ExternalDNS, Amazon ECR, AWS App Mesh, and AWS ALB Ingress Controller.

eksctl create nodegroup --cluster=EKS-1 \
                       --region=ap-south-1 \
                       --name=node2 \
                       --node-type=t3.medium \
                       --nodes=3 \
                       --nodes-min=2 \
                       --nodes-max=4 \
                       --node-volume-size=20 \
                       --ssh-access \
                       --ssh-public-key=DevOps \
                       --managed \
                       --asg-access \
                       --external-dns-access \
