Gitlab Runner Docker 連接期間登錄不工作錯誤：發布 http://docker:2375/v1.40/auth：撥打 tcp：在 67.207.67.3:53 上查找 docker

Question

我在 gitlab runner 上使用 docker executor 作為圖像 我正在使用docker:stable我收到此錯誤：

$ docker login gitlab.mydomain.com:5050 -u myusername-p mytoken
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
error during connect: Post http://docker:2375/v1.40/auth: dial tcp: lookup docker on 67.207.67.3:53: no such host
Cleaning up project directory and file based variables
00:01
ERROR: Job failed: exit code 1

這是我的config.toml

concurrent = 1
check_interval = 0

[session_server]
  session_timeout = 1800

[[runners]]
  name = "dev-env"
  url = "https://gitlab.mydomain.com/"
  token = "REDACTED"
  executor = "docker"
  [runners.custom_build_dir]
  [runners.cache]
    [runners.cache.s3]
    [runners.cache.gcs]
    [runners.cache.azure]
  [runners.docker]
    tls_verify = false
    image = "docker:stable"
    privileged = false
    disable_entrypoint_overwrite = false
    oom_kill_disable = false
    disable_cache = false
    volumes = ["/cache"]
    shm_size = 0

這是我的 ci 文件

deploy-dev:
  stage: deploy
  before_script:
    - apk add make
  script:
    - docker login gitlab.mydomain.com:5050 -u myusnerma -p mytoken
  only:
    - mybranch
  tags:
    - dev

Answer 1

您必須將docker:dind服務添加到您的作業配置中：

deploy-dev:
  variables:
    DOCKER_TLS_CERTDIR: ""
    DOCKER_HOST: "tcp://docker:2375"
  services:
    - docker:dind
  # ...

要使 dind 容器工作，您的運行器必須允許特權容器：

  [runners.docker]
    privileged = true
    # ...

Answer 2

除了privileged = true你還應該 docker 容器內的 map /var/run/docker.sock到主機上的/var/run/docker.sock 。 是這樣的：

concurrent = 1
check_interval = 0
[session_server]
  session_timeout = 1800
[[runners]]
  name = "my-runner"
  url = "https://gitlab.mydomain.com/"
  token = "GITLAB_RUNNER_TOKEN"
  executor = "docker"
  [runners.custom_build_dir]
  [runners.cache]
    [runners.cache.s3]
    [runners.cache.gcs]
    [runners.cache.azure]
  [runners.docker]
    tls_verify = false
    image = "docker:stable"
    privileged = true
    disable_entrypoint_overwrite = false
    oom_kill_disable = false
    disable_cache = false
    volumes = ["/cache", "/var/run/docker.sock:/var/run/docker.sock"]
    shm_size = 0
