GitLab 在本地主机上使用 Docker 运行程序：如何将主机暴露给容器？

Question

我正在学习使用 GitLab CI。

刚才我在 localhost ( external_url "http://localhost") 上使用 GitLab。我已经使用普通ubuntu:20.04映像注册了一个 Docker 运行程序，并尝试在其上运行一些测试作业。

唉，它尝试从容器中的本地主机存储库克隆我的存储库，但无法做到这一点，因为我的本地主机的端口 80 在容器中不可见。

我的 Docker 运行程序如何将主机的 localhost:80 公开为容器的 localhost:80？

Answer 1

好吧，我已经处理了这些事情了。

我已添加network_mode = "host"到我的运行程序配置中，/etc/gitlab-runner/config.toml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"首先在本地搜索容器映像，然后在远程存储库中搜索。
