2. 部署 ingress-nginx

# 1、启动 ExpressVPN
#     ingress-nginx 部署的时候会拉取以下2个镜像文件
#         registry.k8s.io/ingress-nginx/kube-webhook-certgen:v1.1.1
#         registry.k8s.io/ingress-nginx/controller:v1.3.0
# 2、执行以下命令：
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.3.0/deploy/static/provider/cloud/deploy.yaml
# 或者
kubectl apply -f https://github.com/kubernetes/ingress-nginx/blob/controller-v1.3.0/deploy/static/provider/cloud/deploy.yaml

3. 测试：

# kubectl apply -f nginx-ingress.yaml
# kubectl delete -f nginx-ingress.yaml
# 在 hosts 文件中配置：
# 127.0.0.1 nginx.arno
#
# 注意：以下 ingressClassName: nginx 依赖于上面 ingress-nginx 中的 IngressClass 资源
# IngressClass 用于处理规则
# Ingress 用于插件服务于 Service 的规则
