gitlab-runner 注册问题 x509 certificate signed by unknown authority

系统：Ubuntu 18.04.1 LTS

gitlab版本：11.9

使用gitlab服务器域名：https://gitlab.example.com

需要使用到url和token:gitlab服务器地址+/admin/runners

要在GNU / Linux下注册Runner：

1. 运行以下命令：

   gitlab-runner register
   

2. 输入您的GitLab实例URL：

    Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com )
   

https://gitlab.com

输入您获得的令牌以注册Runner：

Please enter the gitlab-ci token for this runner
 
  
xxx
 
 
 
  

 
输入Runner的描述，您可以稍后在GitLab的UI中更改：
 
  
 
  
Please enter the gitlab-ci description for this runner
 
  
[hostame] my-runner
 
 
 
  

 
输入与Runner关联的标签，您可以稍后在GitLab的UI中更改：
 
  
 
  
Please enter the gitlab-ci tags for this runner (comma separated):
 
  
my-tag,another-tag
 
 
 
  

 
输入Runner执行程序：
 
  
 
  
Please enter the executor: ssh, docker+machine, docker-ssh+machine, kubernetes, docker, parallels, virtualbox, docker-ssh, shell:
 
  
docker
 
 
 
  

 
如果您选择Docker作为执行程序，则会要求您将默认图像用于未在其中定义的项目.gitlab-ci.yml：
 
  
 
  
Please enter the Docker image (eg. ruby:2.1):
 
  
alpine:latest
 
 
  
  第五步报错,报错信息如下：

找到gitlab文件夹下,就看到了,把证书文件带上
