如何设置 gitlab-runner 以在 gitlab-ci 中运行 docker 命令？

Question

我尝试配置 gitlab runner，以便在我的.gitlab-ci.yml 文件中使用 docker 命令。

我已经运行了 2 个容器来做到这一点：

• gitlab/gitlab-ce:latest
• gitlab/gitlab-runner:alpine

我已将我的注册跑步者设置为特权模式：

[[runners]]
  name = "first runner"
  url = "http://my.domain.com:8484/"
  token = "mySecretToken"
  executor = "docker"
  clone_url = "http://my.domain.com:8484/"
  [runners.custom_build_dir]
  [runners.cache]
    [runners.cache.s3]
    [runners.cache.gcs]
    [runners.cache.azure]
  [runners.docker]
    tls_verify = false
    image = "node:lts-alpine"
    privileged = true
    disable_entrypoint_overwrite = false
    oom_kill_disable = false
    disable_cache = false
    volumes = ["/cache"]
    shm_size = 0

我的管道可以很好地构建和运行测试。现在我想用我的节点构建文件构建 nginx docker 容器。

当我刚刚运行docker version 命令时，出现了错误：

$ docker version
Client: Docker Engine - Community
 Version:           20.10.1
 API version:       1.41
 Go version:        go1.13.15
 Git commit:        831ebea
 Built:             Tue Dec 15 04:28:35 2020
 OS/Arch:           linux/amd64
 Context:           default
 Experimental:      true
error during connect: Get http://docker:2375/v1.24/version: dial tcp: lookup docker on 8.8.8.8:53: no such host
ERROR: Job failed: exit code 1

也许这是我的.gitlab-ci.yml 的错误：

services:
  - name: docker:dind

stages:
    - construction

variables:
  DOCKER_HOST: tcp://docker:2375/
  DOCKER_DRIVER: overlay2
  # See https://github.com/docker-library/docker/pull/166
  DOCKER_TLS_CERTDIR: ""

deploiement:
  stage: construction
  image: docker:latest
  before_script:
    - docker version
  script:
    - echo "test"

如何配置我的跑步者来执行 docker 命令？我的跑步者设置是否错误？

感谢您的回答！

根据@Dr Claw和@vpalmerini cmets，需要将docker.sock添加到volume中并移除变量和服务。见this thread。

我的.gitlab-ci.yml：

variables:
  DOCKER_DRIVER: overlay2

before_script:
  - df
  - cat /etc/resolv.conf
  - cat /etc/hosts

deploiement:
  image: docker:latest
  before_script:
    - docker version
  script:
    - docker info

我的config.toml：

[[runners]]
  name = "Synology premier runner"
  url = "http://my.domain.com:8484/"
  token = "1UsxGPQmxht6zHPb_y2b"
  executor = "docker"
  clone_url = "http://my.domain.com:8484/"
  [runners.custom_build_dir]
  [runners.cache]
    [runners.cache.s3]
    [runners.cache.gcs]
    [runners.cache.azure]
  [runners.docker]
    tls_verify = false
    image = "node:lts-alpine"
    privileged = true
    disable_entrypoint_overwrite = false
    oom_kill_disable = false
    disable_cache = false
    volumes = ["/var/run/docker.sock:/var/run/docker.sock", "/cache"]
    shm_size = 0

非常感谢您对@Dr Claw 和@vpalmerini 的回答！
