Gitlab runner

Gitlab runner

一、安装：

1. 通过yum安装于本机

   (1) 添加yum源

    curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-ci-multi-runner/script.rpm.sh | sudo bash
   

   (2) 安装

    yum install gitlab-ci-multi-runner
   

   (3) 注册

   • 通过gitlab获取GitLab-CI的url和注册token
   • 运行gitlab-ci-multi-runner register开始注册

2. 通过docker安装部署

   (1)拉取镜像

    docker pull gitlab-runner
   

   (2)启动镜像

    docker run -d --name runnertest-builder --restart always  -v /etc/gitlab-runner:/etc/gitlab-runner  -v /var/run/docker.sock:/var/run/docker.sock  gitlab/gitlab-runner:latest
   

   (3)配置runner

    docker exec -it runnertest-builder gitlab-runner register
   

二、使用：

1. .gitlab-ci.yml

三、遇到的问题：

报错：
fatal: unable to access 'http://gitlab-ci-token:xxxxxx@ip/xxx/citest.git': Failed to connect to xx.xx.xx.xxx port 80: Connection refused

报错:
Reinitialized existing Git repository in /data/builds/0ea06a67/0/。。。backend/.git/
Fetching changes with git depth set to 10...
fatal: git fetch-pack: expected shallow list
fatal: The remote end hung up unexpectedly
ERROR: Job failed: exit status 1

原因：
git版本低会导致用新的git特性不稳定。需要进行git版本升级

解决办法：
升级到与github匹配的版本

步骤如下：

删除旧版本git
yum remove git -y
 
安装3方yum 源，centos7 基础仓库，提供的 git 版本只有到 1.8.3，沒办法使用 git 2 的一些新功能
 
yum install https://centos7.iuscommunity.org/ius-release.rpm
 
安装新版本git
yum install git2u -y
 
验证版本
git --version
 
重新安装runner
yum install gitlab-runner -y

修改runner配置：
vi /etc/systemd/system/gitlab-runner.service
 
ExecStart=/usr/lib/gitlab-runner/gitlab-runner "run" "--working-directory" "/home/gitlab-runner" "--config" "/etc/gitlab-runner/config.toml" "--service" "gitlab-runner" "--syslog" "--user" "gitlab-runner"
改为：
ExecStart=/usr/lib/gitlab-runner/gitlab-runner "run" "--working-directory" "/home/gitlab-runner" "--config" "/etc/gitlab-runner/config.toml" "--service" "gitlab-runner" "--syslog" "--user" "root"

重新注册runner
gitlab-runner register
 
启动runner服务
systemctl daemon-reload
systemctl start gitlab-runner
即可

问题：
ERROR: Job failed: Error response from daemon: pull access denied for dotnet, repository does not exist or may require 'docker login' (executor_docker.go:188:8s)

问题原因：
这是由于以gitlab-runner用户登录，没有权限执行相关命令

解决方法：
将gitlab-runner添加为免密sudo用户
或将
/etc/systemd/system/gitlab-runner.service文件中的
 
ExecStart=/usr/lib/gitlab-runner/gitlab-runner "run" "--working-directory" "/home/gitlab-runner" "--config" "/etc/gitlab-runner/config.toml" "--service" "gitlab-runner" "--syslog" "--user" "gitlab-runner"
修改为：
ExecStart=/usr/lib/gitlab-runner/gitlab-runner "run" "--working-directory" "/home/gitlab-runner" "--config" "/etc/gitlab-runner/config.toml" "--service" "gitlab-runner" "--syslog" "--user" "root"

重新注册runner
gitlab-runner register
 
启动runner服务
systemctl daemon-reload
systemctl start gitlab-runner
即可

问题:
sudo: no tty present and no askpass program specified
ERROR: Job failed: exit status 1

问题原因：sudo之后需要输入密码，没输入超时就会提示这个。

解决办法：免密sudo或不用这个方法，可参考问题二
