docker部署微服务发送sentinel心跳失败 财富值10

2020-03-24 22:14发布


一、该问题的重现步骤是什么?

1. nacos, sentinel, redis, mysql, blade-admin, blade-log以及业务微服务均使用docker部署,参考script/docker-compose.yml方式

2. 所有服务均正常启动,各自功能均能正常访问

3. spring boot admin所有服务的sentinel状态为DOWN

4. 查询各微服务的健康信息:"sentinel":{"status":"DOWN","details":{"dataSource":{},"enabled":true,"dashboard":{"description":"172.30.0.58:8858 can't be connected","status":"DOWN"}}}, IP及端口(172.30.0.58:8858)均正确,但提示:can't be connected

5. 进入容器查看sentinel-record.log.2020-03-24.0提示:WARNING [SimpleHttpHeartbeatSender] Failed to send heartbeat to sentinel.docker_blade_net/172.30.0.58:8858 : java.net.ConnectException: Connection refused (Connection refused)

6. 同一容器内检查连通性:

curl 172.30.0.58:8858

    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever

    link/ether 02:42:ac:1e:00:09 brd ff:ff:ff:ff:ff:ff
    inet 172.30.0.9/16 brd 172.30.255.255 scope global eth0
       valid_lft forever preferred_lft forever



二、你期待的结果是什么?实际看到的又是什么?

容器内的各微服务网络连通性正常,但sentinel心跳提示拒绝连接,微服务的sentinel健康状态为DOWN


三、你正在使用的是什么产品,什么版本?在什么操作系统上?

四、请提供详细的错误堆栈信息,这很重要。

  1. 微服务健康信息:
