“代码都乖乖躺进 GitLab 仓库了，现在该给 CICD 配个‘打工人’了 —— 接下来咱们给 GitLab 安排个 Runner 插件，让它帮咱们自动搬砖～”

1. 获取GitLab Runner注册Token 说明：在GitLab网页端→项目→Settings→CI/CD→Runners→Expand，复制注册Token

2. 回到gitlab-ci目录

   cd /opt/gitlab-ci

3. 解压gitlab-runner压缩包 说明：解压CI/CD相关软件包，准备部署资源

   tar -zxf gitlab-runner-0.43.0.tgz

4. 备份并配置values.yaml 说明：修改GitLab地址、注册Token等核心配置

   # 备份原配置文件
   cp gitlab-runner/values.yaml gitlab-runner/values.yaml.bak
   ​
   # 写入正确配置
   cat > gitlab-runner/values.yaml << EOF

     registry: registry.gitlab.com

5. 部署GitLab Runner（Helm方式）

   helm install gitlab-runner ./gitlab-runner -n gitlab-ci

6. 检查部署状态 说明：验证Runner是否成功部署并运行

   # 查看Helm发布状态
   helm list -n gitlab-ci
   ​
   # 查看K8s资源状态
   kubectl get -n gitlab-ci all

7. 验证注册结果 说明：回到GitLab网页端刷新页面，查看Runner是否成功注册
