简介

本文介绍K8S部署ingress-nginx的方法。

本文使用的K8S和ingress-nginx都是最新的版本。

官网地址

https://kubernetes.github.io/ingress-nginx/deploy/

Ingress里Nginx的代理流程：

k8s 1.28 部署ingress,K8S,k8s,云原生

1.部署ingress-nginx-controller

1.下载Ingress-Nginx部署文件

1.确定版本

首先确定版本：https://github.com/kubernetes/ingress-nginx

k8s 1.28 部署ingress,K8S,k8s,云原生

我K8S是1.28，这里我下载的Ingress-Nginx版本是：v1.9.1（这是我试成功的最新的版本）

注意：我试过1.9.1以上的版本都失败了。

2.下载部署文件

访问：https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.9.1/deploy/static/provider/cloud/deploy.yaml

将它下载一下，这里我将它记录下来：

2.修改部署文件

1.修改镜像

默认镜像是registry.k8s.io，国内无法下载，只能替换成其他镜像。

方法是，去docker hub官网查找其他同版本的镜像，docker里的是可以下载的。详细方法见：这里

这里我修改为这三个版本：

bitnami/nginx-ingress-controller:1.9.1（修改一处）
dyrnq/kube-webhook-certgen:v20230407（修改两处）

如下图所示（红框内，-代表原来的值，+代表修改后的值）

k8s 1.28 部署ingress,K8S,k8s,云原生

2.修改网络模式

ingress是对外提供的，所以要与主机共享ip及端口，在Deployment添加一行配置：

hostNetwork: true

若不添加，后续使用域名:nodeport 访问；添加之后，直接使用域名访问（80和443端口）。

如下图所示：

k8s 1.28 部署ingress,K8S,k8s,云原生

3.支持master节点部署

我这里要支持在master节点部署，所以要加一个配置：

      tolerations:       #设置能在master上部署
      - key: node-role.kubernetes.io/master
        operator: Exists

如下图所示：

k8s 1.28 部署ingress,K8S,k8s,云原生

kubectl apply -f deploy.yaml

命令结果：

k8s 1.28 部署ingress,K8S,k8s,云原生

用命令查看启动结果

kubectl get all -n ingress-nginx

2.部署应用程序

本处部署一个nginx和一个tomcat。

编写配置文件

新建test文件夹，在里边新建nginx-tomcat.yaml文件，内容如下：

apiVersion: v1
kind: Namespace
metadata:
  name: test

---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  namespace: test
spec:
  replicas: 2
  selector:
    matchLabels:
      app: nginx-pod
  template:
    metadata:
      labels:
        app: nginx-pod
    spec:
      containers:
      - name: nginx
        image: nginx:latest
        ports:
        - containerPort: 80

---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: tomcat-deployment
  namespace: test
spec:

  selector:
    matchLabels:

      containers:
      - name: tomcat
        image: tomcat:8.0-alpine
        ports:
        - containerPort: 8080

---
apiVersion: v1
kind: Service
metadata:
  name: nginx-service
  namespace: test
spec:
  selector:
    app: nginx-pod
  clusterIP: None
  type: ClusterIP
  ports:
  - port: 80
    targetPort: 80

---
apiVersion: v1

  namespace: test
spec:
  selector:
    app: tomcat-pod
  clusterIP: None
  type: ClusterIP
  ports:
  - port: 8080
    targetPort: 8080

启动

kubectl apply -f nginx-tomcat.yaml

用命令查看启动结果

kubectl get all -n test

k8s 1.28 部署ingress,K8S,k8s,云原生

用dashboard查看结果

k8s 1.28 部署ingress,K8S,k8s,云原生

3.部署ingress

ingress的作用就是：将ingress-nginx-controller与应用的service连接起来。

编写配置文件

在test文件夹下新建ingress.yaml文件，内容如下：

---
apiVersion: networking.k8s.io/v1
kind: Ingress  
metadata:
  name: test-ingress
  namespace: test
spec:
  ingressClassName: nginx
  rules:
  - host: "tomcat.demo.com"
    http:
      paths:
      - pathType: Prefix
        path: "/"
        backend:
          service:
            name: tomcat-service
            port:
              number: 8080
  - host: "nginx.demo.com"
    http:
      paths:
      - pathType: Prefix
        path: "/"
        backend:
          service:
            name: nginx-service
            port:
              number: 80

启动

kubectl apply -f ingress.yaml

用命令查看启动结果

kubectl get ingress -n test

k8s 1.28 部署ingress,K8S,k8s,云原生

4.测试

1.配置hosts文件

我是Windows系统，修改C:\Windows\System32\drivers\etc\hosts文件，添加一行配置：（ip就是K8S宿主机的IP，后边两个域名对应上边ingress配置的域名）。

192.168.5.193 tomcat.demo.com  nginx.demo.com

如下图所示：

2.访问nginx

访问：http://nginx.demo.com/

k8s 1.28 部署ingress,K8S,k8s,云原生

3.访问tomcat

访问：http://tomcat.demo.com/

至此，ingress部署完毕！！生产环境一般需要用https部署，本文介绍的是http。https方式后边我再研究一下，后边把链接贴出来。

http都通了，https就很简单了，肯定是配置一下ssl证书就可以了。文章来源地址https://www.toymoban.com/news/detail-830749.html
