OpenShift Container Platform 4.x Tested Integrations (for s390x)

Updated -

Tested Integrations are a defined set of specifically tested configurations and interface points between technologies that represent the most common combinations that Red Hat OpenShift Container Platform (OCP) customers are using or deploying for the s390x architecture. For these integrations, Red Hat has directly, or through certified partners, exercised a full range of platform tests as part of the product release process. Issues identified as part of this testing process are highlighted in release notes for Red Hat OpenShift Container Platform. For more information on each of these please see the Red Hat Enterprise Linux Certified Ecosystem, in the hardware and cloud provider spaces.

If you are looking for information on other cpu architectures, please see this article for more information.

It is possible to run Red Hat OpenShift with alternative configurations, not explicitly listed by this page or as part of the product documentation. Please refer to the Red Hat OpenShift Container Platform for more information on how those configurations are supported.
This list of tested integrations is expected to expand over time, however, this page is limited to only covering what OpenShift supported at the time the minor version GA'ed. This means that it is possible for other configurations to be "tested" and/or "supported" that are not listed, due to patch update. Please see the product release notes for more details regarding those configurations.
