组里面
sudo usermod -aG root gitlab-runner
sudo usermod -aG docker gitlab-runner
5.安装并作为服务运行：
sudo gitlab-runner install --user=gitlab-runner --working-directory=/home/gitlab-runner
sudo gitlab-runner start
6.注册Gitlab-Runner ,shell 方式
sudo gitlab-runner register
官网参考链接:https://docs.gitlab.com/runner/register/index.html
7.测试
sudo -u gitlab-runner -H docker info
8.给Gitlab-Runner 执行kubectl权限,拷贝 /root/.kube 文件夹 到 gitlab-runner 用户家目录下，且修改此文件夹属于 gitlab-runner用户和组
chown -R gitlab-runner.gitlab-runner .kube
sudo -u gitlab-runner kubectl get cs
5.安装.NET Core SDK (CentOS7)
在部署Gitlab-Runner的机器上安装SDK,因为Gitlab CI 要构建代码和运行ASP.NET Core单元测试.
sudo rpm -Uvh https://packages.microsoft.com/config/rhel/7/packages-microsoft-prod.rpm
sudo yum update
sudo yum install dotnet-sdk-2.2
