新建k8s nginx容器(需要外网访问)

第一步，创建deploy

apiVersion: extensions/v1beta1   #k8s版本不同，api可能也不同
kind: Deployment
Metadata:
  name: myNginx
  namespace: default
spec:
  replicas: 1
  selector:
    matchLabels:
      app: Nginx
  template:
    Metadata:
      name: web
      labels:
        app: Nginx
    spec:
      containers:
      - name: Nginx
        image: Nginx
        ports:
        - name: Nginx
          containerPort: 80
        volumeMounts:
          - name: html-config
            mountPath: /etc/Nginx/conf.d/Nginx.conf
            subPath: Nginx.conf
            readOnly: true
          - name: nginx-logs
            mountPath: /var/log/Nginx/
      volumes:
      - name: html-config
        configMap:
          name: Nginx.conf
      - name: nginx-logs
        hostPath:
          path: /test-Nginx/logs/

2.创建configmap文件挂载到容器中

kubectl create cm Nginx.conf --from-file=./Nginx.conf

Nginx.conf内容如下

server{
        listen       80;
        server_name             test-Nginx.test.net;
        access_log              /var/log/Nginx/access.log main;
        error_log               /var/log/Nginx/error.log error;

        location / {
                return 200;
        }
}

3.创建ingress，使Nginx可以通过域名访问

apiVersion: extensions/v1beta1    #k8s版本不同，api可能也不同
kind: Ingress
Metadata:
  name: test-Nginx
  namespace: default
spec:
  rules:
  - host: test-Nginx.test.net #域名
    http:
      paths:
      - backend:
          serviceName: service-Nginx    #关联后端的svc
          servicePort: 80　　　　　　　　　#svc的端口号
status:
  loadBalancer:
    ingress:
    - ip: xxx.xxx.xxx.xxx                 #阿里云的k8s的负载均衡地址

4.添加阿里云dns域名解析

 

5.现在就可以在外放访问域名了
