Overview
Deploy CoreNova SSM EKS Admin Bastion AMI (Amazon Linux 2023, Graviton ARM64) as a private administration host for Amazon EKS.
CoreNova SSM EKS Admin Bastion is a private, SSM-first Amazon EKS administration workstation packaged as an Amazon Machine Image. It gives platform engineers, DevOps teams, MSPs, and startup CTOs a controlled EC2 host for kubectl, Helm, eksctl, and k9s without building or maintaining a public SSH jump box.
This is an administration and bastion AMI, not an EKS worker node image. Use it to operate existing or newly created EKS clusters from a private subnet with IAM and Kubernetes RBAC controlled by the buyer.
What you get
- Amazon Linux 2023 hardened base maintained by CoreNova
- SSM-first access model with Amazon SSM Agent and Session Manager Plugin
- SSH key-only fallback with root login and password authentication disabled
- AWS CLI v2 and kubectl multi-version selector for supported EKS minor versions
- Helm, eksctl, k9s, kubectx, kubens, jq, yq, git, tmux, and troubleshooting utilities
- EKS Access Entry example and least-privilege IAM policy templates
- Tool inventory at /etc/corenova/eks-admin-bastion/tool-versions.txt
- Quickstart and examples under /opt/corenova/eks
Best for
- Private EKS administration from a controlled EC2 instance
- Replacing public SSH bastion hosts with Session Manager access
- Standardized kubectl and Helm workstation for platform teams
- MSP or consultant access host in customer AWS accounts
- Security-conscious EKS troubleshooting and cluster inspection
Recommended deployment model
Launch into a private subnet, attach an IAM role with AmazonSSMManagedInstanceCore and your required EKS access policy, and connect with AWS Systems Manager Session Manager. Do not open inbound SSH unless your organization explicitly requires SSH fallback.
Security model
The AMI ships without hardcoded passwords, private keys, AWS credentials, kubeconfigs, or customer data. Buyers control IAM permissions, EKS Access Entries, Kubernetes RBAC, network access, logging retention, and secrets handling in their own AWS accounts.
Architecture and pricing
ARM64 / Graviton. Recommended instance type: t4g.small.
Software fee: $0.04/hour for supported EC2 instance types. This product has charges associated with CoreNova packaging, maintenance, documentation, and seller support. AWS infrastructure costs such as EC2, EBS, NAT gateway, VPC endpoints, public IPv4, and data transfer are billed separately by AWS.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.

Recommended instance type: t4g.small. AMI: ami-002863ac8aaeee5d0 (us-east-1).
Recommended launch model
- Subscribe in AWS Marketplace, then launch in us-east-1.
- Place the instance in a private subnet where it can reach AWS APIs.
- Attach an IAM role with AmazonSSMManagedInstanceCore and the minimum EKS permissions required by your team.
- Do not open inbound SSH to the internet. Use AWS Systems Manager Session Manager for shell access.
- Review EC2 instance, EBS, data transfer, NAT gateway, VPC endpoint, and AWS Marketplace software charges before launch.
First connection with Session Manager
aws ssm start-session --target YOUR_INSTANCE_ID
Optional SSH fallback
If your organization requires SSH fallback, select an EC2 key pair and restrict inbound TCP 22 to trusted administrator networks only.
ssh -i your-key.pem ec2-user@YOUR_PRIVATE_IP
EKS setup
aws eks update-kubeconfig --region YOUR_REGION --name YOUR_CLUSTER_NAME kubectl get nodes helm version eksctl version corenova-eks-check
Installed tools
- AWS CLI v2 and Session Manager Plugin
- kubectl with kubectl-select helper for supported EKS minor versions
- Helm, eksctl, k9s, kubectx, kubens

Sensitive data and credentials
The AMI does not include hardcoded passwords, private keys, AWS credentials, kubeconfigs, or customer data. Customer-created keys, kubeconfigs, and Kubernetes secrets remain in the buyer's AWS account.
Encryption
