Gitlab Auto Deploy 无法连接到 Docker

Question

我已经使用 Helm 在 Kubernetes 上安装了 Gitlab，并尝试让 Auto DevOps 工作，但我从 Auto DevOps 管道中遇到以下问题：

Executing "step_script" stage of the job script 00:01
$ if [[ -z "$CI_COMMIT_TAG" ]]; then # collapsed multi-line command
$ /build/build.sh
Logging in to GitLab Container Registry with CI credentials...

我已经阅读了关于 Docker-in-Docker 的问题，但我无法让它工作。

我也试过设置 DOCKER_HOST: tcp://docker:2375/ 变量，但我仍然得到同样的错误。

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

我的 Gitlab Runner Helm 值如下所示：

gitlabUrl: https://gitlab.mydomain.com
privileged: true
rbac:
  create: true
runnerRegistrationToken: mytoken
runners:
  config: |
    [[runners]]
      executor = "docker"
      privileged = true
      environment = ["DOCKER_TLS_CERTDIR="]
      [runners.docker]
        tls_verify = false
        privileged = true

我尝试使用 Auto-DevOps .gitlab-ci.yml template。

我的集群是使用集群证书的方式集成到Gitlab中的，运行简单CI/CD喜欢

test_project:
  stage: test
  script:
  - npm run test

工作正常

我尝试了 docker:18.09.7、docker:19.03.1 和 docker:latest（以及相应的 -dind 服务，有或没有设置 DOCKER_HOST: tcp://docker:2375/）

我不知道我错过了什么。

//更新

我在 Gitlab 支持的帮助下解决了这个问题。我的问题是我必须使用 [runners.kubernetes] 配置并将 privileged 设置为 true 。我只是在 [runners.docker] 中设置它，因为我认为 Kubernetes Gitlab Runners 会进行该配置。
