k8s部署并测试ingress-nginx的详细过程

 更新时间：2025年04月02日 10:29:38   作者：头未秃  
这篇文章主要介绍了k8s部署并测试ingress-nginx的详细过程,本文通过一个demo示例给大家介绍的非常详细,感兴趣的朋友一起看看吧

对应版本

一、部署ingress-nginx服务

1、下载deploy文件

我这里使用的版本是1.9.6 deploy.yaml

2、修改部分配置信息

修改 Deployment 为 DaemonSet；移除 strategy 字段；

3、这里是我修改完之后的yaml

我这里是1.9.6的 如果不是这个版本按照前面步骤修改即可。

ingress-controller-1.9.6.yaml

    apiVersions:

    operations:
    - CREATE
    - UPDATE
    resources:
    - ingresses
  sideEffects: None

4、部署

kubectl apply -f ingress-controller-1.9.6.yaml

二、部署一个demo服务

1、我这里部署的是tomcat

tomcat9-deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: tomcat9
  name: tomcat9
spec:
  replicas: 3
  selector:
    matchLabels:
      app: tomcat9
  template:
    metadata:
      labels:
        app: tomcat9
    spec:
      containers:
      - image: tomcat:9.0.102-jre17
        name: tomcat
---
apiVersion: v1
kind: Service
metadata:
  labels:
    app: tomcat9
  name: tomcat9
spec:
  ports:
  - port: 8080
    protocol: TCP
    targetPort: 8080
  selector:
    app: tomcat9
  type: NodePort

2、部署

kubectl apply -f tomcat9-deployment.yaml

三、部署ingress

1、对应yaml配置

ingress-tomcat9.yaml

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: tomcat9
spec:
  rules:
    - host: tomcat9.chenxc.com
      http:
        paths:
          - path: /
            pathType: Prefix
            backend:
              service:
                name: tomcat9
                port:
                  number: 8080

2、部署

kubectl apply -f ingress-tomcat9.yaml

四、测试

1、获取tomcat的service的端口

2、修改本地hosts配置

3、访问

到这里说明就成功了
