Docker注册GitLab-Runner报ERROR: Registering runner... failed。。。。: connect: no route to host

本文主要用于记录最近自己再Docker中注册GitLab-Runner时遇见的一些问题，与处理方式

ERROR: Registering runner... failed                 runner=sxWzyrsZ status=couldn't execute POST against http://192.168.29.128:80/api/v4/runners: Post http://192.168.29.128:80/api/v4/runners: dial tcp 192.168.29.128:80: connect: no route to host
PANIC: Failed to register this runner. Perhaps you are having network problems 

注册时出现该错误时的几个排查方向
1.检查宿主机的防火墙是否处于开启状态（我的问题则是由于防火墙没关导致，关闭后重写执行注册脚本就成功了）

查看防火墙当前状态

systemctl status firewalld.service

2.检查注册脚本中的url地址与registration-token是否与GitaLab中的一致

3.检查GitLab是否是Https访问协议，如果是则需要再再注册脚本中加入–tls-ca-file=”GitLab的公钥认证文件“
