spec:
# hostNetwork makes it possible to use ipv6 and to preserve the source IP correctly regardless of docker configuration
# however, it is not a hard dependency of the nginx-ingress-controller itself and it may cause issues if port 10254 already is taken on the host
# that said, since hostPort is broken on CNI (https://github.com/kubernetes/kubernetes/issues/31307) we have to use hostNetwork where CNI is used
# like with kubeadm
# hostNetwork: true
