When running on any other container platform or with any other container engine or runtime — including upstream Kubernetes, cloud provider based Kubernetes services, other Linux distributions, any other non-RHEL Linux distribution, or a non-Red Hat provided container engine or runtime — users will receive updates, but support will not be provided by Red Hat. There is no way to purchase support on any platform other than a Red Hat-supported container platform. Red Hat does not perform any testing or validation of UBI on any non-Red Hat software stack. Any issues should be filed with the respective upstream communities or products.
