1.下载sentinel的jar包

wget https://github.com/alibaba/Sentinel/releases/download/1.8.3/sentinel-dashboard-1.8.3.jar

2.编写dockerfile

[root@k8s-matser01 teste]# cat Dockerfile 
FROM openjdk:8-jdk-alpine
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
ENV LC_ALL "zh_CN.UTF-8"
COPY sentinel-dashboard-1.8.3.jar /tmp/sentinel-dashboard-1.8.1.jar
CMD java ${JAVA_OPTS} -jar /tmp/sentinel-dashboard-1.8.1.jar

3.编写yaml文件

[root@k8s-matser01 teste]# cat sentinel.yaml 
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: sentinel
spec:
  serviceName: sentinel
  replicas: 1
  template:
    metadata:
      labels:
        app: sentinel
      annotations:
        pod.alpha.kubernetes.io/initialized: "true"
    spec:
      containers:
        - name: sentinel
          imagePullPolicy: IfNotPresent
          image: sentinel:v1
          ports:
            - containerPort: 8080
              name: client
          env:
            - name: TZ
              value: Asia/Shanghai
            - name: JAVA_OPTS 
              value: "-Dserver.port=8080 -Dcsp.sentinel.dashboard.server=localhost:8080 -Dsentinel.dashboard.auth.username=sentinel -Dsentinel.dashboard.auth.password=sentinel -Dserver.servlet.session.timeout=7200" # 配置端口 配置账号密码 配置session超时时间,默认账号密码都是sentinel
  selector:
    matchLabels:
      app: sentinel
---
apiVersion: v1
kind: Service
metadata:
  name: sentinel-svc
  labels:
    app: sentinel
spec:
  ports:
    - protocol: TCP
      name: http
      port: 8080
      targetPort: 8080
      nodePort: 31808
  type: NodePort
  selector:
    app: sentinel

4.查看服务

[root@k8s-matser01 teste]# kubectl get pod |grep sentinel
sentinel-0                                1/1     Running   0          12m
[root@k8s-matser01 teste]# kubectl get svc |grep sentinel
sentinel-svc   NodePort    10.100.189.97   <none>        8080:31808/TCP   12m
