k3s - v1.19.13+k3s1

This release updates Kubernetes to v1.19.13

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

:warning: Important Upgrade Note :warning:
If you are using K3s in a HA configuration with an external SQL datastore, and your server (control-plane) nodes were not started with the --token CLI flag, you will no longer be able to add additional K3s servers to the cluster without specifying the token. Ensure that you retain a copy of this token, as is required when restoring from backup. Previously, K3s did not enforce the use of a token when using external SQL datastores.

You may retrieve the token value from any server already joined to the cluster:

cat /var/lib/rancher/k3s/server/token

Changes since v1.19.12+k3s1:

Known Issues

  • There is a regression that may cause issues with deleting nodes due to finalizers not being removed. If you observe a node is stuck for some time and is not being deleted you can describe the node to see if any finalizers remain. If there are any finalizers, you can work around this issue by running the following command to remove the finalizers:
# replace <nodename> with the name of the node
kubectl get node -o name <nodename> | xargs -i kubectl patch {} -p '{"metadata":{"finalizers":[]}}' --type=merge
