Provisioning a Kubernetes Cluster on AWS
Prerequisites:
- AWS Account
- AWS CLI
- Kubectl
- AWS Access and Secret Keys
Step 1: Set Up Your AWS Environment
VPC (Virtual Private Cloud): Create a VPC to isolate your cluster’s network.
# Example command
aws ec2 create-vpc --cidr-block 192.168.0.0/16
Subnets: Set up public and private subnets within your VPC.
# Example command
aws ec2 create-subnet --vpc-id --cidr-block 192.168.1.0/24
Security Groups: Configure security groups to control inbound and outbound traffic.
# Example command
aws ec2 create-security-group --group-name my-security-group --description "My security group"
IAM Roles: Create IAM roles with the necessary permissions.
# Example command
aws iam create-role --role-name my-eks-role --assume-role-policy-document file://eks-trust-policy.json
Step 2: Create an Amazon EKS Cluster
- Open the AWS Management Console and navigate to the Amazon EKS service.
- Click “Create cluster” and provide a name and description.
- Choose the desired Kubernetes version.
- Configure your VPC, subnets, and security groups.
- Set up role-based access control (RBAC) by specifying IAM roles for your cluster’s service and worker nodes.
- Review and create the cluster.

aws eks --region update-kubeconfig --name
Step 3: Launch Worker Nodes
- Create a node group and specify the instance type, desired capacity, and IAM role.
- EKS will automatically create and manage worker nodes for you.
Step 4: Verify Your Cluster
Use kubectl to check if your cluster is up and running:
kubectl get nodes
Step 5: Deploy Applications
Now that your Kubernetes cluster is ready, you can start deploying containerized applications. Use kubectl to create and manage deployments, services, and pods.
Conclusion:
Provisioning a Kubernetes cluster on AWS is a vital step in modern application deployment. With the power of Kubernetes and the scalability of AWS, you can efficiently manage and scale your containerized applications. Follow this guide to get your Kubernetes cluster up and running and embark on your containerization journey with confidence. Happy clustering!
