我正在学习使用GitLab CI.
刚才我在localhost(external_url "http://localhost"(上使用GitLab。我已经注册了一个带有香草ubuntu:20.04映像的Docker运行程序，并尝试在它上运行一些测试作业
遗憾的是，它试图从容器中的localhost存储库克隆我的repo，但无法执行，因为从容器中看不到我的localhost端口80。

我如何才能让我的Docker运行程序将主机的localhost:80公开为容器的localhost:8？
好吧，我已经处理好了这些事情。
我已经在/etc/gitlab-runner/config.toml中将network_mode = "host"添加到我的runner配置中，以使我的docker使用主机网络连接。
此外，我还添加了--pull_policy="if-not-present"，以便首先在本地搜索容器映像，然后在远程repo中搜索。
