原因：docker里面的host不能配置127.0.0.1 或者192.168.0.1 或则宿主机器将无法访问端口
修改配置文件—（涉及到的，需要外部访问的都需要修改）
[root@ubuntu-10 open-falcon]# vim transfer/config/cfg.json{ "debug": true, "minStep": 30, "http": { "enabled": true, "listen": "0.0.0.0:6060" }, "rpc": { "enabled": true, "listen": "0.0.0.0:8433" **#此处监听外面8433. 改成0.0.0.0** }, "socket": { "enabled": true, "listen": "0.0.0.0:4444", "timeout": 3600 }, "judge": { "enabled": true, "batch": 200, "connTimeout": 1000, "callTimeout": 5000, "maxConns": 32, "maxIdle": 32, "replicas": 500, "cluster": { "judge-00" : "127.0.0.1:6080" } }, "graph": { "enabled": true, "batch": 200, "connTimeout": 1000, "callTimeout": 5000, "maxConns": 32, "maxIdle": 32, "replicas": 500, "cluster": { "graph-00" : "127.0.0.1:6070" } }, "tsdb": { "enabled": false, "batch": 200, "connTimeout": 1000, "callTimeout": 5000, "maxConns": 32, "maxIdle": 32, "retry": 3, "address": "127.0.0.1:8088" }修改好之后重启 docker里的服务
[root@ubuntu-10 open-falcon]# ./open-falcon restart transfer再次查看日志
test@ubuntu-10:/tmp/bak$ tail -40 /home/work/open-falcon/agent/logs/agent.log 2018/10/15 02:52:48 var.go:88: => 2018/10/15 02:52:48 var.go:95: <= 2018/10/15 02:52:48 var.go:88: => 2018/10/15 02:52:48 var.go:95: <= 2018/10/15 02:52:48 var.go:88: => 2018/10/15 02:52:48 var.go:95: <= #连接成功，数据传入。查看端口的连接性

补充：docker 镜像启动成功但是无法访问
解决办法：vi /etc/sysctl.conf 或者
vi /usr/lib/sysctl.d/00-system.conf 添加如下代码：
net.ipv4.ip_forward=1重启network服务systemctl restart network 查看是否修改成功
sysctl net.ipv4.ip_forward 如果返回为“net.ipv4.ip_forward = 1”则表示成功了
以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。如有错误或未考虑完全的地方，望不吝赐教。
