about failover create_load_balancer_for_the_kubernetes_api

[louishot]

Hello,

I am a newbie and am testing and verifying the Kubernetes solution on hetzner.
We have a cluster of 3 masters and 4 worker
If I don't enable create_load_balancer_for_the_kubernetes_api, how can Worker nodes connect to the Master node? is it connect 1 of 3 master permanently? if that master is down how to failover?

Thank you

Hi, it's usually best to ask general questions in the discussions section. I like to keep the issue tracker for real problems that users have with the tool :) So I'm changing this to a discussion.

About your question: once the masters are connected to each other in the control plane and the cluster is operational, the worker nodes will connect to the control planel using the internal network inside the cluster. They don't connect through the external load balancer. Instead, they use the default kubernetes service that is created inside the cluster. This service handles the round robin load balancing between the masters.
