K8S安装（三）: 在K8S集群中安装Ingress-Nginx
由于我是安装的最新版本k8s v1.23.4，所以网上别的解决方案安装ingress将会出现问题，此文主要记录在新版本中如何安装Ingress.
前提：k8s集群已经安装好。
接下来步骤中将按顺序安装ingress-nginx-controller
1.下载deploy yaml文件
如果你的集群中没有安装Helm，或者想用YAML文件形式。请copy下面命令下载，因为网络限制原因，如果访问不了，可多访问几次，偶尔会成功。版本为：v1.1.1
官方网址： https://kubernetes.github.io/ingress-nginx/deploy/
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.1.1/deploy/static/provider/cloud/deploy.yaml
此处作为原文备份我将deploy.yaml 粘贴进来：

2.配置docker镜像加速器
登录阿里云用自己的支付宝账号登录注册一个登录进去，控制台里搜索镜像服务即可。点开就会在页面中看到属于自己镜像加速器。
如下为我的加速器地址，您可以通过修改daemon配置文件/etc/docker/daemon.json来使用你们自己的加速器。
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://qr7pk469.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
3.修改deploy.yaml文件
修改步骤1中的yaml文件，搜索关键字image ，您将会发现需要下载相关镜像。
比如： image: k8s.gcr.io/ingress-nginx/controller:v1.1.1@sha256:0bc88eb15f9e7f84e8e56c14fa5735aaa488b840983f87bd79b1054190e660de
由于国内网络限制，k8s.gcr.io地址无法访问，所以需要用国内的镜像来替换这的image
在k8s主机节点上用docker 搜索 ：docker search controller:v1.1.1 --no-trunc
将会看见有2个可用的国内镜像，则将deploy.yaml中 image: k8s.gcr.io/ingress-nginx/controller:v1.1.1@sha256:0bc88eb15f9e7f84e8e56c14fa5735aaa488b840983f87bd79b1054190e660de 替换为loging/ingress-nginx-controller:v1.1.1镜像。
直接使用docker search出来的镜像 loging/ingress-nginx-controller:v1.1.1
docker pull loging/ingress-nginx-controller:v1.1.1下载发现会有问题，不知道什么原因，我未仔细研究，下载到本地的镜像用docker images 查看却无法显示出来。
通过运行docker pull docker.io/loging/ingress-nginx-controller:v1.1.1却发现下载后可正常使用。于是我将原文中的 image: k8s.gcr.io/ingress-nginx/controller:v1.1.1@sha256:0bc88eb15f9e7f84e8e56c14fa5735aaa488b840983f87bd79b1054190e660de替换为
image:docker.io/loging/ingress-nginx-controller:v1.1.1
同样的方法可知 kube-webhook-certgen 镜像的国内镜像地址为 lianyuxue1020/kube-webhook-certgen:v1.1.1
于是将原yaml文件中的image: k8s.gcr.io/ingress-nginx/kube-webhook-certgen:v1.1.1@sha256:64d8c73dca984af206adf9d6d7e46aa550362b1d7a01f3a0a91b20cc67868660替换为image:lianyuxue1020/kube-webhook-certgen:v1.1.1
修改后将文件重命名为 ingress-nginx.yaml并上传到master节点服务器。
修改后的yaml文件为：

通过下面命令安装Ingress服务
kubectl apply -f ingress-nginx.yaml
执行命令后查看master节点启动的所有pod
发现namespace为ingress-nginx的三个pod已经成功完成，status为completed的两个pod为job类型资源，completed表示job已经成功执行无需管它。
查看service kubectl get svc
删除service kubectl delete service nginx-web
