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
