k8s部署应用(k8s部署prometheus)

k8s中已部署zookeeper集群，参见：k8s部署集群版zookeeper3.4

创建deploy定义vim dubbo-admin-deploy.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: dubbo-admin4-deploy
  labels:
    app: dubbo-admin4-deploy
spec:
  replicas: 1
  selector:
    matchLabels:
      app: dubbo-admin4
  template:
    metadata:
      labels:
        app: dubbo-admin4
    spec:
      containers:
        - name: dubbo-admin
          image: apache/dubbo-admin:0.4.0
          imagePullPolicy: IfNotPresent
          command: [ "/bin/bash", "-ce", "java -Dadmin.registry.address=zookeeper://zookeeper34-svc.default:2181 -Dadmin.config-center=zookeeper://zookeeper34-svc.default:2181 -Dadmin.metadata-report.address=zookeeper://zookeeper34-svc.default:2181 -jar /app.jar"]
          readinessProbe:
            tcpSocket:
              port: 8080
            initialDelaySeconds: 60 
            periodSeconds: 20

执行创建deploy：kubectl create -f dubbo-admin-deploy.yaml

注：根据initialDelaySeconds配置，60s后pod才会ready

查看deploy：kubectl get deploy
查看Pod：kubectl get po

创建服务定义vim dubbo-admin-access-service.yaml

apiVersion: v1
kind: Service
metadata:
  name: dubbo-admin-access-service
  labels:
    app: dubbo-admin-access-service
spec:
  selector:
    app: dubbo-admin4
  type: NodePort
  ports:
    - name: dubbo-admin-8080
      port: 8080
      targetPort: 8080
      nodePort: 30088

执行创建服务：kubectl create -f dubbo-admin-access-service.yaml
查看服务：kubectl get svc

浏览器访问以下网址：
localhost:30088
用户名：root，密码：root
