Docker中的Docker执行器在Gitlab-Runner中不起作用（无法连接到docker deamon）

所以我最近尝试了Docker和Gitlab Runner，但似乎我无法得到它的工作。

这是我有的日志：

Running with gitlab-runner 10.0.2 (a9a76a50) on my-docker (c588e5e2) Using Docker executor with image docker:git ... Starting service docker:dind ... Pulling docker image docker:dind ...

Is the docker daemon running?.** See 'docker run --help'. ERROR: Job failed: exit code 125 

什么可能是错误？ Docker自己似乎正在运行，但里面的docker似乎没有工作。

这是我的.toml文件：

 [[runners]] name = my name url = my url token = my token executor = "docker" [runners.docker] tls_verify = false image = "docker:latest" privileged = true disable_cache = false volumes = ["/cache"] shm_size = 0 [runners.cache] 

预先感谢您的帮助！

编辑：多数民众赞成什么“dockerPS”作为输出：
