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.
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.

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.
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.
