Gitlab runner docker无法解析主机

我在我的Ubuntu OS上使用了2个容器：Gitlab-ce和gitlab-runner

容器名称为：gitlab_gitlab_1和gitlab_gitlab-runner_1

我通过gitlab.localhost.com:801访问我的gitlab应用程序

我用这个命令成功注册了一个跑步者：

docker exec -it gitlab_gitlab-runner_1 gitlab-runner register --non-interactive --url http://gitlab_gitlab_1 --registration-token _wgMgEx3nBocYQtoi83c --executor docker --docker-image alpine:latest

然后,当我开始工作时,我收到此错误消息：

Running with gitlab-runner 10.7.1 (b9bba623)
  on 589a617ee407 12ba77f7

fatal: unable to access 'http://gitlab-ci-token:xxxxxxxxxxxxxxxxxxxx@gitlab.localhost.com/root/test.git/': Could not resolve host: gitlab.localhost.com

在这两个容器中,我都可以访问主机名gitlab.localhost.com.
我认为这个问题来自高山图像无法解决主机问题.

我该如何解决这个问题？

谢谢

泊坞窗,compose.yml

version: '3'
services:
  gitlab:
    image: 'gitlab/gitlab-ce:latest'
    restart: always
    hostname: 'gitlab.localhost.com'
    environment:

最佳答案

感谢Tarun Lalwan链接并根据Joyce Babu帖子,有一个undocumented option来自gitlab runner repos in the
[runners.docker]部分

network_mode : Add container to a custom network

所以我必须在config.toml中使用我的网络名称设置此选项

[[runners]]
  ...
  [runners.docker]
    ...
    network_mode = "gitlab_default"

或者从命令行创建运行器时

docker exec -it gitlab_gitlab-runner_1 gitlab-runner register \
--non-interactive \
--url http://gitlab_gitlab_1 \
--registration-token _wgMgEx3nBocYQtoi83c \
--executor docker \
--docker-image alpine:latest \
--docker-network-mode gitlab_default
