github rancher/rke2 v1.20.7+rke2r1

2 years ago

Notice

This release is affected by a bug (#1052) with the --cluster-reset flag which causes a goroutine panic when attempting to reset the etcd cluster membership. It is required to upgrade to v1.20.7+rke2r2 if you intend to leverage etcd cluster reset or etcd restore functionality.

This release updates Kubernetes to v1.20.7
For more details on what's new, see the Kubernetes release notes.

Upgrade Notes

If you installed RKE2 from RPMs (default on RHEL-based distributions), you will need to either re-run the installer, or edit /etc/yum.repos.d/rancher-rke2.repo to point at the latest/1.20 or stable/1.20 channel (depending on how quickly you would like to receive new releases) in order to update RKE2 via yum.
