[Feature Request]: Migration path to ingress_controller = "none"

[MaximilianMeister]

Description

Hi folks,

I initially set up my production cluster with the default ingress controller traefik, which set up the helm chart for traefik.

Now I'd like to manage the traefik helmchart myself via another automation and tried to set ingress_controller = "none"

The problem is that this variable is tied to the hetzner loadbalancer and therefore terraform wants to destroy it. I tried a few procedures to avoid this, but I couldn't find a way to gracefully opt-out of the deployment of the traefik helm chart. I guess it will behave the same way with nginx.

Thanks for any hints
