Gitlab转轮对接机无法解析主机

Question

我在我的Ubuntu操作系统上使用了两个容器: Gitlab-ce和gitlab-runner

容器名称是：gitlab_gitlab_1和gitlab_gitlab-runner_1

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

我成功地使用以下命令注册了一个运行程序：

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，当我开始作业时，我收到以下错误消息：

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，我可以访问主机名gitlab.localhost.com。我认为这个问题来自于无法解决主机的图像高寒。

我怎么才能解决呢？

谢谢

Answer 1

感谢Tarun链接和Joyce帖子，在[runners.docker] section中有一个来自gitlab跑步者repos的[runners.docker] section

network_mode : Add container to a custom network

因此，我必须在config.toml中使用我的网络名设置此选项，如

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

或者当从命令行创建运行程序时

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

Answer 2

我知道这条线是旧的，但我看到到处都有线程指向这个，但没有为我解决。

我收到了同样的错误消息：

致命:无法访问'http://gitlab.maison.fr:82/angular/test1.git/'：无法解析主机: gitlab.maison.fr

将network_mode = "host"添加到config.toml解决了这个问题。

我在本地专用网上的config.toml：

concurrent = 1
check_interval = 0

[session_server]
  session_timeout = 1800

[[runners]]
  name = "mars"
  url = "http://gitlab.maison.fr:82/"
  token = "TCfHAheTUdWMU2-fFNxK"
  executor = "docker"
  [runners.custom_build_dir]
  [runners.cache]
    [runners.cache.s3]
    [runners.cache.gcs]
    [runners.cache.azure]
  [runners.docker]
    tls_verify = false
    image = "gitlab/gitlab-runner:latest"
    privileged = false
    disable_entrypoint_overwrite = false
    oom_kill_disable = false
    disable_cache = false
    volumes = ["/cache"]
    shm_size = 0
    network_mode = "host"

Answer 3

这是为我工作，没有定义网络在码头组成。只需在gitlab配置中添加一个extra_hosts记录，就像我们在其他操作系统中添加一个记录一样。

sudo vim /etc/gitlab-runner/config.toml

  [runners.docker]
tls_verify = false
image = "alpine:latest"
privileged = false
disable_entrypoint_overwrite = false
oom_kill_disable = false
disable_cache = false
volumes = ["/cache"]
shm_size = 0
extra_hosts = ["xxx.xxx.com.cn:192.168.10.110"]
