Error in installing ingress-nginx helm chart

Question

I am installing nginx ingress controller through helm chart and pods are not coming up. Got some issue with the permission.

Chart link - https://artifacthub.io/packages/helm/ingress-nginx/ingress-nginx

I am using latest version 4.2.1

I done debugging as stated here https://github.com/kubernetes/ingress-nginx/issues/4061 also tried to run as root user runAsUser: 0

I think i got this issue after cluster upgrade from 1.19 to 1.22. Previously it was working fine.

Any suggestion what i need to do to fix that?

unexpected error storing fake SSL Cert: could not create PEM certificate file /etc/ingress-controller/ssl/default-fake-certificate.pem: open /etc/ingress-controller/ssl/default-fake-certificate.pem: permission denied

Answer 1

You obviously have permission problem. Looking at the Chart you specified, the are multiple values of runAsUser for different config.

controller.image.runAsUser: 101
controller.admissionWebhooks.patch.runAsUser: 2000
defaultBackend.image.runAsUser: 65534

I'm not sure why these are different, but if possible -

Try to delete your existing chart, and fresh install it.

If the issue still persist - check the deployment / pod events, see if the cluster alerts you about something.

Also worth noting, there were breaking changes in 1.22 to Ingress resource. Check this and this links from the official release notes.
