gitlab-ci - Gitlab Auto Deploy 无法连接到 Docker

问题描述

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

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 Docker-in-Docker 的问题，但我无法让它工作。

我也尝试设置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，例如

test_project:
  stage: test
  script:
  - npm run test

工作正常

我试过docker:18.09.7, docker:19.03.1and 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。

解决方案

// 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]配置并设置privileged在true那里。我只是将它设置[runners.docker]为我认为 Kubernetes Gitlab Runners 会进行该配置。
