Red Hat and AWS site reliability engineering (SRE) experts manage the underlying platform so you do not have to worry about the complexity of infrastructure management. ROSA provides seamless integration with a wide range of AWS compute, database, analytics, machine learning, networking, mobile, and other services to further accelerate the building and delivering of differentiating experiences to your customers.
Red Hat OpenShift Service on AWS clusters are available on the Hybrid Cloud Console. With the Red Hat OpenShift Cluster Manager application for ROSA, you can deploy Red Hat OpenShift Service on AWS clusters to either on-premises or cloud environments.
VolumeDetachTimeout
configuration applied to machine pools for ROSA with HCP. ROSA is applying a VolumeDetachTimeout
configuration of 5 minutes to all machine pools. This prevents issues with node deletion when volumes fail to detach. This only applies to ROSA with HCP.
Configure machine pool disk volume for ROSA with HCP clusters. You can now configure the disk volume size for machine pools in ROSA with HCP clusters. The default disk size is 300 GiB, and you can configure it from a minimum of 75 GiB to a maximum of 16,384 GiB. For more information, see Configuring machine pool disk volume.
ROSA CLI update. The ROSA CLI (rosa
) was updated to a new version. For information about what has changed in this release, see the ROSA CLI release notes. For more information about the ROSA CLI (rosa
), see About the ROSA CLI.
ROSA with HCP multi-architecture cluster update. Red Hat OpenShift Service on AWS (ROSA) with hosted control planes (HCP) clusters created before 25 July, 2024 will migrate to a multi-architecture image on their next upgrade allowing you to use Amazon Web Services (AWS) Arm-based Graviton instance types for your workloads. For more information, see Upgrading ROSA with HCP clusters.
ROSA with HCP cluster node limit update. ROSA with HCP clusters can now scale to 500 worker nodes. This is an increase from the previous limit of 250 nodes. The 250 node limit is an increase from the previous limit 90 nodes on 26 August, 2024. For more information, see ROSA with HCP cluster maximums.
IMDSv2 support in ROSA with HCP. You can now enforce the use of the IMDSv2 endpoint for default machine pool worker nodes on new ROSA with HCP clusters and for new machine pools on existing clusters. For more information, see Creating a default ROSA cluster using Terraform.
Upgrade multiple nodes simultaneously. You can now configure a machine pool to upgrade multiple nodes simultaneously. Two new machine pool parameters, max-surge
and max-unavailable
, give you greater control over how machine pool upgrades occur. For more information, see Upgrading ROSA with HCP clusters.
ROSA with HCP Graviton Arm-based instance types. You can now use Amazon Web Services (AWS) Arm-based Graviton instance types for your workloads in Red Hat OpenShift Service on AWS (ROSA) with hosted control planes (HCP) clusters created after 24 July, 2024. For more information, see AWS Graviton Arm-based instance types.

Approved Access for ROSA clusters. Red Hat Site Reliability Engineering (SRE) managing and proactively supporting ROSA Clusters will typically not require elevated access to customer clusters as part of the normal operations. In the unlikely event should Red Hat SRE (Site Reliability Engineer) need elevated access, the Approved Access functionality provides an interface for customers to review and approve or deny access requests.
Elevated access requests to ROSA clusters and the corresponding cloud accounts can be created by Red Hat SRE either in response to a customer-initiated support ticket or in response to alerts received by a Red Hat SRE, as part of the standard incident response process. For more information, see Approved Access. This is applicable to ROSA and Red Hat OpenShift Service on AWS (classic architecture).
ROSA command enhancement. The rosa describe
command has a new optional argument, --get-role-policy-bindings
. This new argument allows users to view the policies attached to STS roles assigned to the selected cluster. For more information, see describe cluster.
Expanded customer-managed policy capabilities. You can now attach customer-managed policies to the IAM roles required to run both ROSA (classic architecture) and ROSA clusters. Furthermore, these customer-managed policies, including the permissions attached to those policies, are not modified during cluster or role upgrades. For more information, see Customer-managed policies.
Permission boundaries for the installer role policy. You can apply a policy as a permissions boundary on the ROSA installer role. The combination of policy and boundary policy limits the maximum permissions for the Amazon Web Services(AWS) Identity and Access Management (IAM) entity role. ROSA includes a set of three prepared permission boundary policy files, with which you can restrict permissions for the installer role since changing the installer policy itself is not supported. For more information, see Permission boundaries for the installer role. This is applicable only to Red Hat OpenShift Service on AWS (classic architecture).
Cluster delete protection. You can now enable the cluster delete protection option, which helps to prevent you from accidentally deleting a cluster. For more information on using the cluster delete protection option with the ROSA CLI, see edit cluster. For more information on using the cluster delete protection option in the UI, see Creating a cluster with the default options using OpenShift Cluster Manager.

ROSA with HCP is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process. For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope. |
OIDC provider endpoint URL update. Starting with ROSA CLI version 1.2.7, all new cluster OIDC provider endpoint URLs are no longer regional. Amazon CloudFront is part of this implementation to improve access speed, reduce latency, and improve resiliency. This change is only available for new clusters created with ROSA CLI 1.2.7 or later. There are no supported migration paths for existing OIDC provider configurations.
If you configure your cluster using external OIDC configuration and set the --user-auth
flag to disabled
, the console pods might enter a crash loop. (OCPBUGS-29510)
The OpenShift Cluster Manager roles (ocm-role
) and user roles (user-role
) that are key to the ROSA provisioning wizard might get enabled accidentally in your Red Hat organization by another user. However, this behavior does not affect the usability.
The htpasswd
identity provider does not function as expected in all scenarios against the rosa create admin
function.
To use the latest version of the Red Hat OpenShift Service on AWS (ROSA) CLI, rosa
, download the ROSA CLI (rosa
) from the Hybrid Cloud Console. If you already have this tool, the procedure is the same for updates.
Download the file from the Hybrid Cloud Console.
Unzip the downloaded file.
Move the file to the /usr/bin/rosa
directory by running the following command:
$ sudo mv rosa /usr/bin/rosa
Confirm your version by running the following command:
$ rosa version
<version>
Your ROSA CLI is up to date.
Some features available in previous releases have been deprecated or removed. Deprecated functionality is still included in ROSA and continues to be supported; however, it will be removed in a future release of this product and is not recommended for new deployments.
ROSA non-STS deployment mode. ROSA non-STS deployment mode is no longer the preferred method for new clusters. Instead, users must deploy ROSA with the STS mode. This deprecation is in line with our new ROSA provisioning wizard UI experience at https://console.redhat.com/openshift/create/rosa/wizard.
Label removal on core namespaces. ROSA is no longer labeling OpenShift core using the name
label. Customers should migrate to referencing the kubernetes.io/metadata.name
label if needed for Network Policies or other use cases.
