nginx-ingress-controller

[Montassar Dridi]

Hello

I'm using google kubenretes engine. My cluster node version is 1.7. Since that version became unsupported by Google cloud for creating new cluster, I need to use 1.8 or 1.9. 

I'm having issues implimenting my nginx-ingress-controller yaml file at the new versioned cluster but I keep getting this error :

         Using build: https://github.com/bprashanth/contrib.git - git-92b2bac when using gcr.io/google_containers/nginx-ingress-controller:0.8.3

and this error hen using quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.9.0

         It seems the cluster it is running with Authorization enabled (like RBAC) and there is no permissions for the ingress controller. Please check the configuration

here is my my nginx-ingress-controller file

reply-all for the record.

Have you followed the step by steps at: https://cloud.google.com/community/tutorials/nginx-ingress-gke

It works very well, makes you install the nginx ingress with helm.

The chart is at: https://github.com/kubernetes/charts/tree/master/stable/nginx-ingress

If you look under the /templates directory you will find all the proper RBAC settings.
