updateStrategy in nginx-ingress-controller cannot be zero

[lzecca78]

Hi!
while we were installing the module version 1.13.1 we had the following problem:

DaemonSet.apps "nginx-ingress-controller-internal" is invalid: spec.updateStrategy.rollingUpdate.maxUnavailable: Invalid value: intstr.IntOrString{Type:0, IntVal:0, StrVal:""}: cannot be 0

What we did was to add the following jsonPatch:

- op: replace
  path: /spec/updateStrategy/rollingUpdate/maxUnavailable
  value: 1

Kubernetes version : EKS 1.22

Thank you @lzecca78 , we found later that this field is not working on 1.22, but should work on 1.23+.

Your patch is the correct fix for the version 1.22
