CoreNova SSM EKS Admin Bastion AMI (Amazon Linux 2023, Graviton ARM64): private Amazon EKS administration bastion for teams replacing public SSH jump hosts. Includes AWS CLI v2, Session Manager Plugin, kubectl version selector, Helm, eksctl, k9s, IAM examples, and AL2023 hardening.
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.

Dimensions summary
You pay an hourly software fee for each running instance, billed by the hour with no upfront commitment. The 17 dimensions all use ARM64 Graviton instance types, so you pick the size that fits your workload. They fall into three families: t4g burstable sizes (micro through xlarge), m6g and m7g general-purpose sizes (medium through xlarge), and c6g and c7g compute-focused sizes (medium through xlarge). Larger sizes carry higher hourly rates. AWS charges EC2, storage, and network infrastructure separately from this software fee.
Top-of-mind questions for buyers
The hourly fee covers only the pre-configured management host software: Amazon Linux 2023 with pre-installed kubectl, Helm, eksctl, and k9s. AWS bills EC2 compute, EBS storage, NAT Gateway, VPC Endpoint, and network transfer separately. You also manage IAM permissions, EKS access, and patching yourself.
The software fee applies per running instance per hour. A stopped instance does not accrue the hourly software fee. Stopped instances may still incur AWS storage charges for the attached EBS volume, which AWS bills separately from this listing.
Each dimension bills the same hourly fee structure but maps to a different ARM64 Graviton instance type. The t4g sizes are burstable, m6g and m7g are general-purpose, and c6g and c7g are compute-focused. Pick the size that matches your workload; the hourly rate scales with size.
