Losing a PEM key in AWS can be problematic because the key is required to access instances securely. once you’ve lost or misplaced a PEM key in AWS, there’s no direct way to retrieve or recover it from AWS itself. This is by design to maintain the security of your instances. The private key is meant to remain confidential, and AWS does not store or keep copies of user-generated keys for security reasons.

Recovering Lost PEM Keys in AWS: A Step-by-Step Guide

In this guide, we will walk through the steps to set up a jump box on an Amazon EKS cluster. A jump box is a secure server that acts as a gateway for accessing resources in a private network.

Prerequisites​

• An existing Amazon EKS cluster.
• kubectl configured to access your EKS cluster.
• AWS CLI installed and configured.

Steps to Set Up the Jump Box​

1. Create a Bastion Host: Launch an EC2 instance in the same VPC as your EKS cluster.
2. Configure Security Groups: Ensure the security group allows SSH access and communication with the EKS cluster.
3. Install Required Tools: Install kubectl, AWS CLI, and other necessary tools on the EC2 instance.
4. Access the Jump Box: SSH into the EC2 instance and use it to interact with the EKS cluster.
