Build a Secure Private EKS Cluster on AWS Using a Bastion

Lock Down Your Kubernetes: Private EKS + Bastion in One Workflow

What you'll learn
- Understand the fundamentals of Amazon EKS (Elastic Kubernetes Service) and how it fits into AWS architecture.
- Configure networking components such as VPC, subnets, route tables, and security groups for a private EKS environment.
- Access and manage the private cluster via Bastion Host using kubectl and AWS CLI.
- Deploy and manage worker nodes inside a private subnet using IAM roles and policies.

Requirements
- No prior experience with Kubernetes or AWS EKS is required — this course starts from the basics.
- A basic understanding of cloud computing will be helpful but not mandatory.
- A Windows, macOS, or Linux system with internet access.
- Willingness to learn and explore AWS services such as EC2, IAM, and VPC.

Description
In today’s cloud-driven world, security and automation go hand in hand. This course is designed to help you master both by guiding you through the process of creating afully private Amazon EKS (Elastic Kubernetes Service) clusterusingTerraform— with access restricted to asecure Bastion host.

You will start by understanding howTerraformsimplifies infrastructure provisioning using Infrastructure as Code (IaC). Then, you’ll learn to design ahighly secure AWS VPCwith both public and private subnets, configure route tables, and deploy aBastion hostto manage access to private resources safely.

Next, you’ll deploy aprivate EKS clusterthat cannot be accessed directly from the internet. You’ll learn how to connect to the cluster via Bastion using SSH tunneling and kubectl, ensuring your workloads stay private and protected.

Throughout the course, we’ll cover essential AWS networking components,IAM roles and permissions,security groups, andEKS node group configurations— all managed and automated through Terraform scripts.

By the end of this course, you’ll have a complete, production-ready setup with best practices forsecurity, scalability, and automation. Whether you’re aDevOps engineer, cloud architect, or developer, this course will equip you with the practical skills to build and manage private Kubernetes environments confidently on AWS.

Who this course is for:
- Beginners who want to learn how to set up and manage a private AWS EKS cluster from scratch.
- Cloud enthusiasts looking to gain hands-on experience with EKS, EC2, IAM, and networking in AWS.
- Anyone curious about secure, private Kubernetes deployments with bastion-only access.
