docker - 在gitlab-ci的docker executor中添加/etc/hosts

Question

寻求这方面的帮助。我是 gitlab-ci 的新手，虽然对 docker 有点经验。

我所有让我的 docker executor 成功构建的尝试都失败了:

Running with gitlab-runner 11.1.0 (081978aa)
  on my-runner 28d98f88
Using Docker executor with image docker:latest ...
Starting service docker:dind ...
Using locally found image version due to if-not-present pull policy

fatal: unable to access 'https://gitlab-ci-token:xxxxxxxxxxxxxxxxxxxx@cicd.home/root/gocryptme.git/': Could not resolve host: cicd.home
ERROR: Job failed: exit code 1

简而言之:

Could not resolve host: cicd.home

已经尝试了到目前为止我遇到的所有建议。

我的.gitlab-ci.yml

image: docker:latest
services:
  - docker:dind

stages:
  - build
  - test
  - release
  - deploy

variables:
  DOCKER_CI_IMAGE: cicd.home:4567/root/cidemo:cicd

before_script:
  - whoami
  - echo '10.11.0.130 cicd.home' >> /etc/hosts

build-image:
  stage: build
  tags:
    - docker
  script:
    - docker build --pull -t $DOCKER_CI_IMAGE .
    - docker push $DOCKER_CI_IMAGE

确定 before_script: 部分不会产生预期的输出。

这是我的config.toml

concurrent = 1
check_interval = 0

[[runners]]
  name = "my-runner"
  url = "https://cicd.home/"
  token = "28d98f88b621865293c49c7fadfc5d"
  executor = "docker"
  [runners.docker]
    tls_verify = false
    privileged = true
    disable_cache = false
    volumes = ["/cache", "/var/run/docker.sock:/var/run/docker.sock:rw"]
    shm_size = 0
    pull_policy = "if-not-present"
  [runners.cache]

对我来说，添加到/etc/hosts 的过程似乎在这里不起作用。

在 Gitlab CI 运行器的 config.toml 中，您可以向 config.toml 添加一个设置，这样您就可以在不触及/etc/hosts 的情况下实现这一点。你可以

[runners.docker]
# ... other settings ...
  extra_hosts = ["cicd.home:10.11.0.130"]

您可以在此处阅读有关 extra_hosts 配置的更多信息:https://docs.gitlab.com/runner/configuration/advanced-configuration.html#the-runnersdocker-section
