1.第一步，下载deploy.yaml文件

2.修改deploy.yaml文件

3.创建deployment、svc、ingress

4.为了可以使用域名访问，修改hosts文件

5.访问服务

1.第一步，下载deploy.yaml文件

 wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.1.1/deploy/static/provider/cloud/deploy.yaml

注意1：需要自己配置raw.githubusercontent.com域名解析，如果不会的话跳转下面这篇文章

https://blog.csdn.net/weixin_44293949/article/details/121863559

注意2：一定先去查自己的k8s支持哪个版本的controller，现在k8s的更新迭代很快，很多以前的东西都被弃用了

2.修改deploy.yaml文件

有两个镜像需要下载，如果不是国外服务器的话，建议先提前下载，这是国内两个镜像

registry.cn-hangzhou.aliyuncs.com/google_containers/nginx-ingress-controller 
registry.cn-hangzhou.aliyuncs.com/google_containers/kube-webhook-certgen

端口的暴露方式也要修改: 将 type: LoadBalance修改为type: NodePort

以下是修改完image的deploy.yaml

3.创建deployment、svc、ingress

对于path那一部分的修改，1.23版本做了调整，如果是旧版本，需要查阅一下代码规范

---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - image: nginx:latest
        name: nginx
        imagePullPolicy: IfNotPresent
        ports:
          - containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
  name: app-service
  namespace: default
spec:
  ports:
    - port: 80
      targetPort: 80
      protocol: TCP
  selector:
    app: nginx
---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: app-ingress
spec:
  ingressClassName: nginx
  rules:
    - host: "cwy.jqq.com"
      http:
        paths:
        - path: /
          pathType: Prefix
          backend:
            service:
              name: app-service
              port: 
                number: 80

4.为了可以使用域名访问，修改hosts文件

windows：windows -> system32 -> drivers -> etc -> hosts

Linux：vim /etc/hosts

5.访问服务

kubectl get svc -n ingress-nginx

 域名:上述查阅到的端口
