Gitlabrunnerdocker无法解析主机

我在Ubuntu操作系统上使用了2个容器：Gitlab-ce和gitlab-runner

容器名称是：gitlab_gitlab_1和gitlab_gitlab-runner_1

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

我使用以下命令成功注册了跑步者：

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，出现以下错误消息：

Running with gitlab-runner 10.7.1 (b9bba623)
  on 589a617ee407 12ba77f7
Using Docker executor with image alpine:latest ...

fatal: unable to access 'http://gitlab-ci-token:xxxxxxxxxxxxxxxxxxxx@gitlab.localhost.com/root/test.git/': Could not resolve host: gitlab.localhost.com
ERROR: Job failed: exit code 1

在这两个容器中，我都可以访问主机名gitlab.localhost.com。我认为问题来自无法解决主机的高山图像。

我该如何解决？

谢谢

回答：

感谢Tarun Lalwan链接，并根据Joyce Babu的帖子，gitlab运行器回购中

有一个未记录的选项[runners.docker] section

network_mode : Add container to a custom network

所以，我在用我的网名来设置这个选项config.toml像

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

或者从命令行创建跑步者

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 \
--docker-network-mode gitlab_default
