Kubectl and aws cli setup in Linux

Steps:

1. Linux:

    sudo apt-get update && sudo apt-get install -y kubectl
   

2. MacOS:

    brew install kubectl
   

3. Windows:

   • Download the latest version of kubectl from the official Kubernetes release page: https://kubernetes.io/docs/tasks/tools/install-kubectl-windows/

   • Add the downloaded executable to your system's PATH.

4. Verify the installation:

    kubectl version --short --client
   

Configuring AWS CLI:

1. Install AWS CLI:

   • Follow the instructions here: https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-files.html

2. Configure AWS CLI:

    aws configure
   

   • You'll be prompted to enter your AWS access key, secret key, default region, and output format.

3. Verify AWS CLI Configuration:

    aws ec2 describe-instances
   

Setting up AWS IAM for EKS:

1. Create IAM Role:

   • Open the IAM console in the AWS Management Console.

   • Navigate to "Roles" and click "Create Role."

   • Choose "EKS" as the service that will use this role and select "Allows Amazon EKS to manage your clusters."

2. Attach Policies:

   • Attach the policies AmazonEKSClusterPolicy and AmazonEKSServicePolicy to the role.

3. Create Kubernetes Config:

   • After creating the EKS cluster, update your kubeconfig with the cluster details.

       aws eks --region <region> update-kubeconfig --name <cluster_name>
     

4. Verify Configuration:

    kubectl get nodes
   

Additional Tips:

• Ensure that you have the necessary AWS CLI and kubectl versions compatible with your EKS cluster.

• Always follow security best practices, such as restricting AWS IAM permissions to the minimum required.

• Keep your AWS CLI and kubectl configurations secure, especially access keys and secrets.

These steps provide a basic setup for using kubectl with AWS EKS. For more detailed information, refer to the official documentation for kubectl and AWS CLI.
