I have a GKE private cluster with a Linux node pool of 2 nodes. The internal IP addresses of the nodes changes everytime it is recreated due to auto-repar/auto-upgrade. I have an external monitoring system for the nodes to check the uptime which polls the IP addresses of the nodes and most of the time it fails because of the IP address changes.
I would like to have the auto-repair mode enabled to have healthy nodes, so I won't be able to avoid the restarts.
Is it possible to have static internal IP addresses for the nodes every time they are recreated?
