k8s搭建nginx并代理应用

创建deployment.yaml

apiVersion: apps/v1
kind: Deployment      
metadata:
  name: pc-deployment
  namespace: xiao
spec: 
  replicas: 1
  selector:
    matchLabels:
      app: nginx-xiao
  template:
    metadata:
      labels:
        app: nginx-xiao
    spec:
      containers:
      - name: nginx
        image: nginx:latest
        ports:
        - containerPort: 80

创建service-nodeport.yaml

[root@master nginx]# cat service-nodeport.yaml 
apiVersion: v1
kind: Service
metadata:
  name: service-nodeport
  namespace: xiao
spec:
  selector:
    app: nginx-xiao
  type: NodePort # service类型
  ports:
  - port: 80
    nodePort: 30002 # 指定绑定的node的端口(默认的取值范围是：30000-32767), 如果不指定，会默认分配
    targetPort: 80
#NodePort服务可以暴露多个端口。您可以通过在Service定义中指定多个ports来达到这个目的。每个port定义都会##创建一个新的NodePort服务，其端口号由NodePort和ServicePort的组合决定
#需要添加一个name字段
[root@master nginx]# cat service-nodeport.yaml 
apiVersion: v1
kind: Service
metadata:
  name: service-nodeport
  namespace: xiao
spec:
  selector:
    app: nginx-xiao
  type: NodePort # service类型
  ports:
  - name: fw1
    port: 80
    nodePort: 30002 # 指定绑定的node的端口(默认的取值范围是：30000-32767), 如果不指定，会默认分配
    targetPort: 80
  - name: fw2
    port: 81
    nodePort: 30003
    targetPort: 81

#查看pod和svc状态
[root@master nginx]# kubectl get pod,svc -n xiao
