RKE2 - v1.23.1+rke2r1

This release is RKE2's first in the v1.23 line. This release updates Kubernetes to v1.23.1.

As this release includes a number of significant changes from previous versions, we will not make v1.23 available via the stable release channel until v1.23.2+rke2r1 or later.

Before upgrading from earlier releases, be sure to read the Kubernetes Urgent Upgrade Notes.

Known Issues

• #2323: When using embedded etcd and the initial server is started with --agent-token, and this agent-only token does not match the server --token value, additional servers cannot join the cluster. This will be fixed in a subsequent release.
• #1447 - When restoring RKE2 from backup to a new node, you should ensure that all pods are stopped following the initial restore:

curl -sfL https://get.rke2.io | sudo INSTALL_RKE2_VERSION=v1.23.1+rke2r1
rke2 server \
  --cluster-reset \
  --cluster-reset-restore-path=<PATH-TO-SNAPSHOT> --token <token used in the original cluster>
rke2-killall.sh
systemctl enable rke2-server
systemctl start rke2-server

Changes since RKE2 v1.22.5+rke2r1 (when the release-1.22 branch was forked from master)

• Disable windows crictl version check (#2308)
• Bump versions for v1.23.1-rc1+rke2r1 (#2307)
