问题

我用 docker compose 制作了一个项目 . 它适用于localhost . 我想用这个基础来测试或分析Gitlab Runner的代码 . 我解决了很多问题，比如安装docker compose，运行和构建选定的容器并在容器中运行命令 . 第一份工作跑了并成功（!!!），但是在"before_script"之前，以下工作失败了：

无法在unix：///var/run/docker.sock上连接到Docker守护程序 . docker守护程序是否正在运行？ ...来自守护程序的错误响应：冲突 . ...来自守护程序的错误响应：冲突 .

我不明白为什么 . 我做错了什么？我再说一遍：管道的第一项工作运行良好 "success" 消息！管道的每个其他工作都失败了 .

全输出：
