双栈 部署ingress-nginx

下载ingress-nginx yaml

wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/baremetal/deploy.yaml
# 部署环境为私有环境没有lb 所有把Deployment 改成DaemonSet 同时网络模式使用hostNetwork
# 同时配文件 跟启动参数修改
# kubelet 参数node-ip 为ipv6 模式记得修改 service ipFamily: IPv6 模式不然新版本webhook 会报错
# 报错内容 Error from server (InternalError): error when creating "STDIN": Internal error occurred: failed calling webhook "validate.nginx.ingress.kubernetes.io": Post https://ingress-nginx-controller-admission.ingress-nginx.svc:443/extensions/v1beta1/ingresses?timeout=30s: no endpoints available for service "ingress-nginx-controller-admission"
