Lock Down Your Kubernetes: Private EKS + Bastion in One Workflow
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 a fully private Amazon EKS (Elastic Kubernetes Service) cluster using Terraform — with access restricted to a secure Bastion host.
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
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 a fully private Amazon EKS (Elastic Kubernetes Service) cluster using Terraform — with access restricted to a secure Bastion host.
You will start by understanding how Terraform simplifies infrastructure provisioning using Infrastructure as Code (IaC). Then, you’ll learn to design a highly secure AWS VPC with both public and private subnets, configure route tables, and deploy a Bastion host to manage access to private resources safely.
Next, you’ll deploy a private EKS cluster that 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, and EKS 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 for security, scalability, and automation. Whether you’re a DevOps engineer, cloud architect, or developer, this course will equip you with the practical skills to build and manage private Kubernetes environments confidently on AWS.
