ingress 官方网站
ingress 仓库地址
ingress-nginx v1.1 最新版本 v1.1
适用于Kubernetes 版本 v1.19+ （也包括 v1.19 ）
Kubernetes-v1.22+ 需要使用 ingress-nginx>=1.0，因为 networking.k8s.io/v1beta 已经移除
直接部署 ingress-nginx
直接部署比较简单，直接拉去 github 的文件就可以了，如果遇到长时间无响应，可以终止任务从新拉取。
拉取镜像部分，可以修改为一下的镜像地址
$ wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.1.0/deploy/static/provider/baremetal/deploy.yaml
$ sed -i 's@k8s.gcr.io/ingress-nginx/controller:v1.1.0\(.*\)@willdockerhub/ingress-nginx-controller:v1.1.0@' deploy.yaml
$ sed -i 's@k8s.gcr.io/ingress-nginx/kube-webhook-certgen:v1.1\(.*\)$@hzde0128/kube-webhook-certgen:v1.1@' deploy.yaml
$ kubectl apply -f ingress-nginx.yaml
