Gitlab CI中的Docker执行程序通过错误的URL传递给Git repo

标签： docker gitlab-ci gitlab-ci-runner

我在http://gitlab.example.com等域上的内部服务器上设置了Gitlab服务器。我还使用shell executor和使用docker executor的跑步者注册了跑步者，两者都在与Gitlab服务器相同的机器上。

我有这个非常基本的.gitlab-ci.yml文件

runtest:
    script:
        - npm install

当我使用shell executor通过跑步者运行时，一切正常。检查了repo，它运行npm install。

但是，当我通过配置为docker executor的跑步者运行时。我收到以下错误：

Running with gitlab-ci-multi-runner 9.4.2 (6d06f2e)

问题在于，我的Gitlab服务器位于名为gitlab.example.com的子域上，并且转轮试图从http://example.com签出代码。好像docker执行器传递了错误的服务器url，因此无法正确检查Git repo。

我无法弄清楚为什么两个参赛者之间存在差异，以及在哪里配置Gitlab以便为所有参赛者使用正确的git回购路径？

编辑：这是运行ps aux | grep gitlab

这是由跑步者的网络设置引起的。在主机和docker执行程序之间自动设置的网桥位于本地网络的“外部”。因此，docker容器无法看到网址gitlab.example.com。

我通过添加

解决了这个问题 
network_mode = "host"

到docker runner的config.toml。

这样，跑者与主机共享同一个网络，因此可以获得所需的访问权限。
