英文:
Gitlab-runner in docker with ci/cd dind error
问题
无法连接到位于服务器内部 Docker 上运行的 GitLab Runner。该 GitLab Runner 已成功注册到我的 GitLab。但是，当我运行 CI/CD 时出现错误：
错误: 无法连接到 Docker 守护程序，地址为 tcp://docker:2375。Docker 守护程序是否正在运行？
我用于 GitLab Runner 的 config.toml 文件
请告诉我如何修复这个错误。
我已经多次重新创建了 GitLab Runner 并重新创建了 CI 文件，但都没有成功。我是这样创建 GitLab Runner 的 -
docker run -d --name gitlab-runner --restart always -v /srv/gitlab-runner/config:/etc/gitlab-runner -v /var/run/docker.sock:/var/run/docker.sock gitlab/gitlab-runner:latest
然后进入 Docker 内部，我运行了以下命令 -
gitlab-runner register --url https://gitlab.com --token <my_token>

英文:
I have gitlab-runner running inside the docker on my server. This gitlab-runner is successfully registered for my gitlab.
But when I run ci/cd I get an error:
ERROR: Cannot connect to the Docker daemon at tcp://docker:2375. Is the docker daemon running?
my config.toml file for gitlab-runner
Please tell me how to fix this error.
I've already recreated gitlab-runner and redid the ci file several times. Nothing worked. I created gitlab-runner with the command -
docker run -d --name gitlab-runner --restart always -v /srv/gitlab-runner/config:/etc/gitlab-runner -v /var/run/docker.sock:/var/run/docker.sock gitlab/gitlab-runner:latest
Then going into the docker itself I ran the command -
gitlab-runner register --url https://gitlab.com --token <my_token>

当您使用docker run来启动您的runner时，您还需要传递--privileged标志。
docker run --privileged ...
您可能还需要在作业中设置变量DOCKER_HOST和DOCKER_TLS_CERTDIR。
myjob:
# ...
variables:
DOCKER_HOST: "tcp://docker:2375"
DOCKER_TLS_CERTDIR: ""
英文:
When you do docker run to start your runner, you also need to pass the --privileged flag.
docker run --privileged ...
You may also need to set the variables DOCKER_HOST and DOCKER_TLS_CERTDIR in your job.
myjob:
# ...
variables:
DOCKER_HOST: "tcp://docker:2375"
DOCKER_TLS_CERTDIR: ""
