问题1、zabbix proxy 与 server不能正常发送数据
zabbix-server容器报错如下：
158:20200302:075118.359 cannot accept connection from proxy "log1" at "172.17.0.1", allowed address: "x.x.x.x": connection is not allowed 159:20200302:075119.360 cannot accept connection from proxy "log1" at "172.17.0.1", allowed address: "x.x.x.x": connection is not allowed
zabbix-proxy-server容器报错如下：
143:20200302:155110.352 cannot send proxy data to server at "x.x.x.x": connection is not allowed 143:20200302:155111.353 cannot send proxy data to server at "x.x.x.x": connection is not allowed
原因分析：
出现上述的原因是由于zabbix代理在与server端进行通信的时候，需要通过docker0(ip为：172.17.0.1)，在web界面配置代理的时候，并没有在代理服务器的ip地址栏填上docker0这个地址，导致proxy与server不能正常发数据。
解决：
在代理地址这里同时吧docker0的地址填写上去
