Red Hat Advanced Cluster Management for Kubernetes 2.6 Support Matrix
Red Hat Advanced Cluster Management for Kubernetes (RHACM) provides the tools and capabilities to address common challenges that administrators and site reliability engineers face as they work across a range of environments, including multiple data centers, private clouds, and public clouds that run Kubernetes clusters. For more details, see the product documentation.
RHACM provides the following capabilities:
- Easily provision Red Hat OpenShift Container Platform clusters and offer complete cluster lifecycle management (create, upgrade, destroy) from a single console. Discover and onboard existing clusters into a consistent management domain.
- Use policies to automatically configure and maintain consistency of security controls required by industry or self-imposed corporate standards.
- Deploy and maintain day 2 operations of business applications distributed across your cluster landscape.
Supported platforms for RHACM
RHACM has two main components:
- A server component called the “hub cluster” where the management tools and user interface run
- A client component that is installed on all Kubernetes clusters that can be managed by the “hub cluster”
- Note: You do not have to use a dedicated cluster for your hub cluster.

For product lifecycle information for RHOCP, see Red Hat OpenShift Container Platform Life Cycle. RHACM is not supported on RHOCP versions that have reached their end-of-life status.
For RHACM product lifecycle information, see Lifecycle and update policies.
Note: As the pace of change in public cloud features is high, constantly changing and evolving, the compatibility for RHACM is correct at GA of the product. Best effort basis during errata cycle for public cloud vendors introduced breaking changes (intended or unintended) to existing functionality. Any other changes or additions would be considered as a Request For Enhancement (RFE), which is evaluated for potential inclusion in future releases. An RFE can be requested using standard support mechanisms. For more details on Red Hat Support, see What is Commercially Reasonable Support?
For Kubernetes services, see Public Cloud Kubernetes support statement.
Feature support
RHACM allows you to perform actions on the clusters that it manages, and provides features for interacting with and providing information about those clusters. This section outlines the status of features support that you can perform on clusters.
