无法连接到 tcp://docker:2375 处的 Docker 守护程序。docker 守护进程是否正在运行？在 docker push 通过 Gitlab CI

Question

在 Gitlab CI 中，当我想推送我的图像时，我得到：

Cannot connect to the Docker daemon at tcp://docker:2375. Is the docker daemon running?

这是代码：

docker-push:
  stage: publish
  image: docker:stable
  services:
    - docker:dind
  before_script:
    - *inject-gopath
    - docker login -u gitlab-ci-token -p $GITLAB_PERSONAL_ACCESS_TOKEN $REGISTRY_URL
    # $CI_BUILD_TOKEN
  script:
    - docker build --build-arg GITLAB_TOKEN=${GITLAB_PERSONAL_ACCESS_TOKEN} --target=prod -t $REGISTRY_PACKAGE_API_NAME:$CI_BUILD_ID .
    - docker build --build-arg GITLAB_TOKEN=${GITLAB_PERSONAL_ACCESS_TOKEN} --target=prod -t $REGISTRY_PACKAGE_API_NAME:latest .
    - docker push $REGISTRY_PACKAGE_API_NAME:$CI_BUILD_ID
    - docker push $REGISTRY_PACKAGE_API_NAME:latest

这是输出：

奇怪的是我在图像中docker-stable，所以我应该有可用的 docker，而且上一步docker login运行良好......

这是来自 Gitlab 的错误，还是我做错了什么？

PD：我正在使用 Gitlab.com

PD2：我可以手动推送图像而没有任何问题

根据评论，这只是一个 GitLab 问题。对于自由运行者，不能保证它总是有效。在这种情况下，docker 守护进程不可用，因此您的构建将持续失败，直到 GitLab 检测到错误时重新启动运行器。

请注意，这是我的假设，因为错误经常出现，然后几个小时后它就消失了。正如您所看到的，我的Gitlab 论坛主题没有收到任何人的回复，因此我担心您无法解决此问题。如果任务关键，则运行您自己的运行程序，以便您可以在失败时重新启动它
