2.2.3版本docker部署，服务启动时偶发：java.net.ConnectException: [NACOS HTTP-POST] The maximum number of tolerable server reconnection errors has been reached

[YS1127]

作者们，你们好。目前遇到一个问题，咨询一下：docker部署nacos 2.2.3版本以及一个网关服务跟个业务服务，服务启动时候，业务服务会偶尔出现java.net.ConnectException: [NACOS HTTP-POST] The maximum number of tolerable server reconnection errors has been reached问题导致服务不可用。但是网关服务又正常，nacos也是正常的，重启业务服务又很正常。我想咨询下是什么原因导致的。下面是docker-compose.yml的内容：

其中business-service服务启动时候会偶发上述问题。

java.net.ConnectException: Connection refused (Connection refused)

This is the reason which means your configured nacos server address not right, or you do not export nacos port to your client.

No more response from author for a long time, and this problem seems env problem.

解决了，是由于docker-compose文件没有进行nacos健康检测，业务服务在nacos服务启动之前启动，导致了业务服务一直连不上nacos导致的（nacos后面启动成功，但是不知道什么原因连接不上），加了健康检测，强制业务服务在nacos服务启动之后再启动就没再出现该问题。
