I want to setup Rancher in HA and off course the kubernetes cluster needs also be HA.
- As I understand HA concept says to setup a kubernetes cluster with RKE and run rancher a as deployment / statefulset there. So kubernetes (RKE) takes care of the HA.
What is the desired paradigm? Do I use this RKE cluster where rancher runs also for my workload or do I need to provision a second kubernetes cluster via rancher which runs my workload?
2.How to deal with no external Loadbalancer available?
The first picture here is showing that it is recommended to use HA with an external loadbalancer:
In previous installations I used metalLB als loadbalancer. I am unfamiliar with helm. If I understood right, rancher was installed via helm in the HA manual provided on rancher website.
What is the best practice to use metallb as loadbalancer and to get rid of the nginx-ingress pods which are using host network? Does the solution will be kept after the next kubernetes or rancher update?
