I have a K8s cluster that I created with RKE and has been added to Rancher. I have containers that are going to bind to port 80 and 443 on the host, and I don’t want to use an ingress controller, so I added the config to remove the ingress:
ingress:
provider: none
When I run rke up, it gets to a point where it tries to remove the existing ingress controller, but then fails.

I can see there is a pod that is supposed to delete the ingress, and it appears to have finished, since I don’t see the ingress controller pods anymore.
$ kubectl get pods --all-namespaces | grep ingress
kube-system rke-ingress-controller-delete-job-ctbpg 1/1 Running 0 9m21s
$ kubectl logs -n kube-system rke-ingress-controller-delete-job-ctbpg
namespace "ingress-nginx" deleted
Running rke up again, results in the same errors.
Meanwhile, Rancher is not able to communicate with the cluster.
This cluster is currently Provisioning; areas that interact directly with it will not be available until the API is ready.
Exit status 1, Error from server (ServiceUnavailable): the server is currently unable to handle the request
How do I recover it so Rancher can communicate with the cluster again.
