[Rancher] Will Rancher fix the issue and release a patch, if the problem is root-caused in Kubernetes?

Article Number: 000020451

Resolution

Yes, should there be a critical need, Rancher can provide patch fixes to address issues root-caused in RKE/RKE2/K3S provisioned Kubernetes clusters. As a first option, Rancher will investigate if the fix is already available in a later version of Kubernetes. If it is, Rancher will provide a newer version of its product that is validated and certified to work with the later Kubernetes version that has the fix. Or validate and certify one of its existing versions to work with the later Kubernetes version that has the fix.

Further, Rancher can submit a PR for the fix to Kubernetes for consideration to be accepted upstream. However, there is no guarantee that the PR will be accepted and merged into upstream Kubernetes.
Rancher provides regular patch releases of RKE, RKE2 and K3S which aim to package all the upstream critical fixes.
