Gitlab自动部署连接Docker失败

Question

我已经使用Helm在Kubernetes上安装了Gitlab，并试图让Auto DevOps工作，但我从Auto DevOps管道中得到以下问题:

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...

我读过关于Docker-in-Docker的问题，但是我无法使它工作。

我也尝试设置DOCKER_HOST: tcp://docker:2375/变量，但我仍然得到相同的错误。

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

我的Gitlab Runner Helm值看起来像这样:

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模板。

我的集群使用集群证书方法集成到Gitlab中，并运行简单的CI/CD，如

test_project:
stage: test
script:
- npm run test

没问题我尝试了docker:18.09.7,docker:19.03.1和docker:latest(以及相应的-dind服务，无论是否设置DOCKER_HOST: tcp://docker:2375/)

我不知道我错过了什么。

我在Gitlab Support的帮助下解决了这个问题。我的问题是，我不得不使用[runners.kubernetes]配置和设置privileged到true那里。我只是在[runners.docker]中设置它，因为我认为Kubernetes Gitlab runner会这样配置。
