docker 中的 Squid 返回 502,但在主机上运行时可以正常工作

我对在主机和 docker 上运行的 squid 5.6 使用相同的配置。当我在主机(Ubuntu 22.10)上运行它时,它工作正常,但当我从ubuntu/squid映像运行它时,我收到 502 错误网关错误。

以下是我通过 docker 运行它的方法:

docker run -v /etc/squid/squid.conf:/etc/squid/squid.conf -p 3128:3128 ubuntu/squid

这似乎是 ubuntu/squid 镜像的问题,而不是 docker 本身的问题。该镜像目前标记为 beta 或 edge,不稳定。我构建了一个基于 alpine 的 squid 镜像,它解决了我的问题。
