January 2024: CMS Gold Image Updates

________________________________________________________________________



Overview 

Below, you will find this month's Center for Medicare and Medicaid Services (CMS) Gold Images (GIs) updates from the CMS Hybrid Cloud Team.

Upcoming Updates

* *Red Hat Enterprise Linux 9 (RHEL9) CMS GI available now:*
* The new RHEL9 CMS GI better aligns to Acceptable Risk Safeguards (ARS) 5. As such, there are major differences between RHEL9 and previous versions.
* Please read the RHEL9 Usage Guide [ https://cloud.cms.gov/rhel9-usage-guide ] available on Cloud.CMS.Gov [ https://cloud.cms.gov/ ] (CCG) and test/develop the new RHEL9 in your lower environments before deploying it live into production.

* *Amazon Linux 2023 with Elastic Kubernetes Service (EKS) Optimization CMS GI available now: *
* Note that existing launch template configurations, based on the EKS-optimized AL2 GI, will not work for AL2023, as the node initialization process has changed.
* Please review the Amazon-published documentation  [ https://docs.aws.amazon.com/eks/latest/userguide/al2023.html ]highlighting the changes and the CCG page: Changes from AL2 to AL2023 [ https://cloud.cms.gov/eks-changes-from-al2-to-al2023 ].

* *Amazon Linux 2023 (AL2023) CMS GI:*
* Be aware that as an added security measure, the /tmp directory has been mounted with the NOEXEC option, which will not allow the execution of binaries within /tmp. 
* This change may impact 3rd-party tools that execute scripts out of the /tmp directory, like Packer.
* Packer does have the option to specify a different directory to execute scripts from (see the documentation [ https://developer.hashicorp.com/packer/docs/provisioners/shell#remote_folder ] for more details).


* *CMS Marketplace Customers to utilize "Bring Your Own License" (BYOL) Red Hat GIs only:*
* For CMS Marketplace customers, please note that Marketplace Information Technology Group (MITG) has a dedicated license for Red Hat, which includes premium support. Thus, if a Marketplace customer utilizes a regular Red Hat Enterprise Linux (RHEL) GI and not a BYOL RHEL, they will incur unnecessary cost. 
* Note that all BYOL GIs have "byol" in the GI name.

* *Windows 2016 (WIN2016) OS End of Life (EOL) in January 2027:*
* In anticipation of Microsoft's Windows 2016 operating system EOL, the last CMS WIN2016 GI will be released in 2026.
* Please plan to upgrade to a newer version of Windows (2019 or 2022) before Open Enrollment (OE) begins in 2026. 
* Additional information will be available in 2025.
