Description
What happened:
ref: #1292 (comment)
What you expected to happen:
Ingress should work properly in ipv6.
How to reproduce it (as minimally and precisely as possible):
Following the ingress-nginx guide on https://kind.sigs.k8s.io/docs/user/ingress/
with the addition of enabling ipv6
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
networking:
ipFamily: ipv6
nodes:
- role: control-plane
kubeadmConfigPatches:
- |
kind: InitConfiguration
nodeRegistration:
kubeletExtraArgs:
node-labels: "ingress-ready=true"
authorization-mode: "AlwaysAllow"
extraPortMappings:
- containerPort: 80
hostPort: 80
protocol: TCP
- containerPort: 443
hostPort: 443
protocol: TCPAnything else we need to know?:
Note that the docker port forwarding seems to work correctly.
example: just simply running nginx directly on the kind node is accessible from the host.
