标签：Ingress name kubernetes 部署 app ingress nginx io k8s
一：下载Ingress-controller.yaml 文件
在k8s master 机器上执行以下载命令
wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/nginx-0.20.0/deploy/mandatory.yaml
或者 官网默认下载最新的yaml：
-
wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/mandatory.yaml
如果下载不成功，不慌，我这有现成的，直接复制粘贴

二：下载nginx-ingress-controller:2.0镜像
docker pull registry.cn-qingdao.aliyuncs.com/kubernetes_xingej/nginx-ingress-controller:0.20.0
三：执行mandatory.yaml 文件
kubectl apply -f mandatory.yaml
如果有安装Dashboard（没有请跳过） 可以直接在页面上看到 nginx-ingress-controller 的运行状态！
创建测试pod 、service
四：执行ingress-nginx.ymal 文件（ingress 规则）
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: ingress-nginx
namespace: htcf
annotations:
# use the shared ingress-nginx
kubernetes.io/ingress.class: "nginx"
# 开启use-regex，启用path的正则匹配
nginx.ingress.kubernetes.io/use-regex: "true"
spec:
rules:
- host: nginx.kube.com
http:
paths:
- path: /
backend:
serviceName: k8snode2
servicePort: 80
查看生效的ingress规则： kubectl get ing
serviceName 对应 service
servicePort 对应
五：
在访问机器配置host，win10客户机在目录：C:\Windows\System32\drivers\etc，在host里增加如下 10.168.0.173 nginx.kube.com 或 10.168.0.125 nginx.kube.com host(ingress部署的机器ip对应访问的域名) 配置完后直接在客户机浏览器访问 http://nginx.kube.com/ ，能正常访问nginx。 没写全，随后有空在更新！！！！！！标签：Ingress,name,kubernetes,部署,app,ingress,nginx,io,k8s 来源： https://blog.csdn.net/weixin_42269089/article/details/120207197
