v1.21.0

Feature Highlights & Upgrade Notes

Load Balancer IPs set to Private IPs

If networking support is enabled, the load balancer IPs are now populated with the private IPs, unless the load-balancer.hetzner.cloud/disable-private-ingress annotation is set to true. Please make sure that you configured the annotation according to your needs, for example if you are using external-dns.

Provided-By Label

We introduced a the label instance.hetzner.cloud/provided-by, which will be automatically added to all new nodes. This label can have the values cloud or robot to distinguish between our products. We use this label in the csi-driver to ensure the daemonset is only running on cloud nodes. We recommend to add this label to your existing nodes with the appropriate value.

kubectl label node $CLOUD_NODE_NAME instance.hetzner.cloud/provided-by=cloud
kubectl label node $ROBOT_NODE_NAME instance.hetzner.cloud/provided-by=robot

Load Balancer IPMode Proxy

Kubernetes KEP-1860 added a new field to the Load Balancer Service Status that allows us to mark if the IP address we add should be considered as a Proxy (always send traffic here) and VIP (allow optimization by keeping the traffic in the cluster).

Previously Kubernetes considered all IPs as VIP, which caused issues when when the PROXY protocol was in use. We have previously recommended to use the annotation load-balancer.hetzner.cloud/hostname to workaround this problem.

We now set the new field to Proxy if the PROXY protocol is active so the issue should no longer appear. If you only added the load-balancer.hetzner.cloud/hostname annotation for this problem, you can remove it after upgrading.
