在docker中添加主机重定向 [英] add hosts redirection in docker

问题描述

我在虚拟机中使用gitlab。我将使用gitlab-ci（在同一个虚拟机中），与docker。

对于访问我的gitlab，我使用域git.local（重定向到我的VM在我的电脑上，重定向到我的虚拟机中的127.0.0.1。）

当我启动测试时，测试返回：

致命：无法访问' http：// gitlab-ci-token：[e-mail]/thib3113/ESCF.git/ '：无法解析主机'git.local'

所以我的问题是：如何为git.local添加重定向到容器IP？我看到docker的 arg -h< host> ，但是我不知道如何告诉gitlab使用这个参数。或者可能是一个配置来告诉docker使用容器dns？

我看到这样：如何让Docker Gitlab CI转接器访问其父主机上的Git？ / a>
但同样的问题，我不知道如何添加参数：/。

解决方案

根据 GitLab CI Runner Advanced配置，您可以尝试在GitLab CI转轮中使用 extra_hosts param。
在 /etc/gitlab-runner/config.toml ：

  [[runners]] 
 url =http：// localhost / ci
 token =TOKEN
 name =my_runner
 executor =docker 
 [runners.docker] 
 host =tcp：//< DOCKER_DAEMON_IP>：2375
 image =...
 ... 
 extra_hosts = [localhost：192.168.0.39] 
  

有了这个例子， git将尝试从 localhost 克隆，它将使用 192.168.0.39 作为此主机名的IP。

I use gitlab in a Virtual machine . And I will use gitlab-ci (in the same VM), with docker .

For access to my gitlab, I use the domain git.local ( redirect to my VM on my computer, redirect to the 127.0.0.1 in my VM ).

And when I launch the tests, the test return :

fatal: unable to access 'http://gitlab-ci-token:[e-mail]/thib3113/ESCF.git/': Couldn't resolve host 'git.local'

So My question is: How add a redirection for git.local to the container IP ? I see the arg -h <host> for docker, but I don't know how to tell gitlab to use this argument. Or maybe a configuration for tell docker to use the container dns?

I see this: How do I get a Docker Gitlab CI runner to access Git on its parent host? but same problem, I don't know how add argument :/ .

解决方案

According to the GitLab CI Runner Advanced configuration, you can try to play with the extra_hosts param in your GitLab CI runner. In /etc/gitlab-runner/config.toml :

[[runners]]
  url = "http://localhost/ci"
  token = "TOKEN"
  name = "my_runner"
  executor = "docker"
  [runners.docker]
    host = "tcp://<DOCKER_DAEMON_IP>:2375"
    image = "..."
    ...
    extra_hosts = ["localhost:192.168.0.39"]

With this example, when inside the container running the test git will try to clone from localhost, it will use the 192.168.0.39 as IP for this hostname.
