Red Hat Advanced Cluster Management for Kubernetes 2.5 Support Matrix

Updated -

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 Kubernetes 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.

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.

Could you please switch that to a single KB for all ACM releases or at least a master page that links to the KBs of each ACM release? Something we can bookmark and keep referencing long term instead of having to search for the new page every time there's a new ACM release?

Yes I see the list of links to the KBs of previous ACM releases, and I just verified that the KBs of older releases were updated with links to newer releases. Well, that's not a fixed URL but works well enough.
