Amazon EKS & Azure AKS¶

Kubernetes v1.33 Support¶

Benefit

Stay current with the latest Kubernetes release, unlocking new features and ongoing support.

Support for Kubernetes v1.33 is being added for Amazon EKS and Azure AKS. This includes:

Provisioning of new clusters with v1.33
Upgrading existing clusters from earlier versions to v1.33

AKS 1.33 Cluster Provisioning¶

AKS 1.33 Cluster Upgrade¶

EKS 1.33 Cluster Provisioning¶

AmazonLinux2 Deprecation in EKS 1.33

AWS has deprecated AmazonLinux2 in EKS 1.33. By default, when you create a new cluster with v1.33, the default node AMI family is set to AmazonLinux2023.

For more information, see the AWS documentation on Amazon Linux 2 AMI deprecation.

For existing clusters using AmazonLinux2:

Before upgrading to EKS 1.33, you must:

Add a new node group based on AmazonLinux2023
Test and validate the new node group with your application pods
Migrate pods from the old node group to the new node group
Delete the old node group after migration is complete
Then proceed with the EKS 1.33 upgrade

Important: If any existing EKS cluster with AmazonLinux2 is upgraded to EKS 1.33 directly without adding node groups based on AmazonLinux2023, the node group upgrade will fail with the following error:

internal error: failed to get aws session, InvalidParameterException: AMI Type AL2_x86_64 is only supported for kubernetes versions 1.32 or earlier { RespMetadata: { StatusCode: 400, RequestID: "462022b3-da9b-4d90-a2b9-2d12b9586de3" }, Message_: "AMI Type AL2_x86_64 is only supported for kubernetes versions 1.32 or earlier" }

Upstream Kubernetes for Bare Metal and VMs¶

Enhanced Debug Capabilities¶

Benefit

Direct debug log download functionality has been added for upstream clusters, providing enhanced debugging capabilities. Users can now directly download logs from nodes to troubleshoot issues more effectively.

Previously users had to ssh to the nodes to see these logs, now this option is available on the every node card with an option to view/download debug logs.

RHEL 10 Support¶

Benefit

Support has been added for Red Hat Enterprise Linux (RHEL) 10 operating system. This allows customers to leverage RHEL 10 based nodes for Rafay MKS clusters.

ARM Support Enhancement¶

Benefit

Complete ARM architecture support has been added for Ubuntu 24.04 LTS and Ubuntu 22.04 LTS on both master and worker nodes. This enables customers to leverage ARM-based infrastructure for their Kubernetes workloads.

Previously only worker node support was added and only minimal blueprint support was available.

Platform Version v1.1.0¶

Benefit

New platform version v1.1.0 provides enhanced cluster management capabilities with integrated core components and automated utilities.

The new platform version v1.1.0 has been added, which includes integration of the Chisel core component and cluster utils version controller component. The cluster utils component includes utilities pushed to the nodes for self-healing, certificate rotation, and monitoring.

This will help us to push changes to the cluster utils via the platform version upgrade, enabling seamless updates and improved cluster maintenance capabilities.

RCTL Enhancement¶

Force Delete¶

Benefit

A new force delete option has been added to RCTL to allow force delete the cluster object if delete failed for any reason.

Usage:

./rctl delete cluster <cluster-name> --force

Add-ons, Workloads & Blueprints¶

Cluster Overrides¶

Benefit

Improves usability and provides more flexibility for administrators.

Two key UI enhancements:

Custom Input for Managed Add-ons – Resource selector previously only supported drop downs for custom add-ons. Now, a free-form Custom Input option is available, enabling overrides for managed add-ons directly from the UI.

Enhanced Placement UI – Placement configuration has been redesigned for clarity, especially in scenarios where admins create overrides for clusters across projects (e.g., using labels).

Artifact Files¶

Benefit

Improves reliability of add-on deployments by automatically retrying artifact fetches before failing.

When artifact fetches (from Git or Helm repos) fail due to transient network issues, the system now retries automatically. This avoids the need to create new add-on versions solely for re-attempting artifact pulls.

Zero-Trust Access¶

Relay Agent¶

Benefit

Improves security by eliminating the need to deploy privileged containers.

The init container is being removed from the relay-agent pod deployed on clusters, resulting in a more secure and simplified deployment.

GitOps¶

Pipelines¶

Benefit

Pipelines respect stage dependencies while maximizing concurrency, dramatically improving overall efficiency.

Historically, Rafay’s GitOps pipeline executed all stages sequentially, regardless of dependencies. While effective for simpler workflows, this limited performance for complex operations. With this enhancement, the pipeline engine supports Directed Acyclic Graphs (DAGs) enabling stages to execute in parallel where dependencies permit.

Environment Manager¶

Reconciliation on Environment Runs¶

Benefit

Improves operational efficiency and reduces deployment times.

Previously, redeploying an environment always redeployed all resources, even if unchanged. With selective resource reconciliation, admins can now specify the reconcile_resources field to redeploy only targeted resources.

Example: In a failover where only DNS updates are required, admins can reconcile the DNS resource without redeploying the entire environment. If no resources are specified, the system redeploys all resources by default.

Environment Deletion and Failure States¶

Benefit

Provides clearer lifecycle management and better visibility into environment operations.

Environments now support three actions: Deploy, Destroy, and Delete (which performs a Destroy followed by removal of the environment object).

Enhancements include:

New distinct status states
Ability to filter environments by Active, Inactive, Deploy Failed, and Delete Failed in both the Environments list and Dashboard
For environments in Delete Failed status, admins can review logs, clean up resources, and use a new remove object action to manually delete the environment

Namespace¶

Ephemeral Storage Resource Quota Limits¶

Benefit

Improved resource management and cost control through enforcement of ephemeral storage quotas at the namespace level.

A previous release introduced ephemeral storage limits as namespace quotas via non-UI interfaces. This has now been extended to the UI, making configuration easier.

Cost Management¶

Chargeback Reports¶

Benefit

Enables metadata-enriched chargeback reports for better visibility and more accurate cost allocation across tenants.

Earlier release introduced Chargeback summary reports aggregated by namespace. These now support custom label-based metadata enrichment, enabling more precise chargeback reporting for multi-tenant clusters. This capability is also available through the UI.

Agents¶

PV Requirement¶

Benefit

Agents no longer require a Persistent Volume (PV), simplifying deployment and reducing infrastructure overhead.

In previous releases, agents required a PV. Starting with agents v3.7+, this requirement has been removed, allowing for more flexible and streamlined deployments.

Bug Fixes¶

Bug ID	Component	Description
RC-43141	Env Manager	Resolved an issue where environment input variables were incorrectly reverted to their previous values
RC-42554	Workloads	Resolved an issue where values.yaml in a Workload Template Artifact did not update to the latest version unless the template’s Chart version was changed
RC-40894	Backup & Restore	Resolved an issue that prevented deletion of the backup agent in certain edge-case scenarios
