k3s - v1.22.8+k3s1

This release updates Kubernetes to v1.22.8, and fixes a number of issues.

For more details on what's new, see the Kubernetes release notes.

Changes since v1.22.7+k3s1:

• Add ability to specify etcd snapshot list output format (#5132) (#5179)
• Fixed a bug that prevented users from using k3s secrets-encryption rotation after upgrading from older K3s versions. (#5169)
• Add --json flag for k3s secrets-encrypt status (#5198)
• k3s secrets-encrypt prepare can now be used on control-plane only nodes (#5228)
• Fix function arg call (#5234) (#5236)
• Add net util funcs (#5245)
• Release 1.22 fix 700 (#5246)
• IPv6 only (#5260)
• The embedded containerd has been bumped to v1.5.10-k3s1 (#5231)
• Backport cleanups and bugfixes from master (#5251)
• When using the unsupported --disable-agent flag, kube-scheduler will now be started when a node is available.
• Server nodes with only etcd/control-plane/etcd+control-plane roles can now be added to the cluster in any order, as long as the first node has the etcd role.
• Any alarms present on the embedded etcd datastore are now reported and cleared at startup. This should allow for graceful recovery after exceeding and subsequently raising the etcd quota size.
• The embedded Helm controller can now cease management of existing HelmChart releases, supports setting a failure policy for install/update operations, and allows trusting custom CA certs for remote chart repositories. (#5280)
• Secondary etcd-only nodes will now successfully bootstrap containerd and the kubelet before a control-plane node has joined the cluster. (#5302)
• Update Kubernetes to v1.22.8-k3s1 (#5272)
• The packaged coredns version has been bumped to v1.9.1 (#5309)
• Defragment etcd datastore before clearing alarms; don't delete temp etcd db while reconciling
• The embedded etcd database is now defragmented on startup.
• Fixed an issue that could cause restart of managed etcd nodes to occasionally fail while reconciling bootstrap data. (#5340)
• Wrap containerd.New (#5362)
