The `sudo apt update` command is used on Debian-based Linux distributions like Ubuntu to update the package lists for repositories configured in the system.

### Installing 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
```

### Installing 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
```

### Installing 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
```

\##For all these commands First make one directory using any name >> go to the directory>> execute these commands.

**## By using the command "aws configure" log into the instance**&#x20;

### 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 \
                       --full-ecr-access \
                       --appmesh-access \
                       --alb-ingress-access
```
