docker pull bladex/sentinel-dashboard:latest

docker run --name sentinel --restart=always -d -p 8858:8858 bladex/sentinel-dashboard:latest

各个应用引入依赖

com.alibaba.cloud
spring-cloud-starter-alibaba-sentinel
2021.1


com.alibaba.csp
sentinel-datasource-nacos

配置DashBoard地址

在nacos 平台配置通用common.yml

spring：
  cloud:
    sentinel:
      transport:
        dashboard: 10.0.0.54:8858
      eager: true
      datasource:
        ds:
          nacos:
            server-addr: 10.0.0.54:8848
            namespace: 6404e5e5-a30f-4e0a-bc05-72fa16f89274
            group-id: project_web
            rule-type: flow
            data-id: sentinal-config
            data-type: json

线上(看看线上nacos配置)

spring：
  cloud:
    sentinel:
      transport:
        dashboard: 114.55.116.233:8858
      eager: true
      datasource:
        ds:
          nacos:
            server-addr: 10.0.0.54:8848
            namespace: 6404e5e5-a30f-4e0a-bc05-72fa16f89274
            group-id: project_web
            rule-type: flow
            data-id: sentinal-config
            data-type: json

新增限流配置文件
