我已经设置了在 vagrant VM 中运行的 coreos。我想设置私有 docker 注册表。我拉了注册表,我可以运行它。以下是运行注册表的输出

在 ubuntu 主机上的浏览器中访问 172.17.42.1:5000 和 192.168.65.27:5000 显示等待很长时间但最终无法连接。

我参考了这篇文章,但我的流浪汉没有提到文章中提到的条目。

如何在 coreos-vagrant 上运行 docker-registry 并使用在主机上运行的浏览器连接到它?

我可以看到你正在尝试做的两个问题。

  1. 您无法从主机操作系统访问在 Vagrant VM 中运行的 docker 容器。
  2. 您正在寻找用于管理私有 docker 注册表的 Web UI,但我认为您正在运行的 docker 映像(库/注册表)不提供此功能。

第 1 项:请注意,您正在运行的私有 Docker 注册表不提供管理 Web UI。它在端口 5000 上提供的服务不是网站;它供命令行 docker 用于在您的私有注册表中推送和拉取图像。如果您需要管理 Web UI,您可以考虑运行附加服务,例如https://github.com/atc-/docker-registry-web(我没有尝试过,但看起来很有希望)。

第 2 项:如果您想从 Vagrant VM 的主机操作系统(可能是 Windows 或 OSX,因为如果您的主机操作系统是 Linux,您可能不需要 Vagrant)访问 Vagrant-VM 托管的 docker 容器的端口,那么我建议您打开一个到您的 CoreOS Vagrant VM 的 ssh 隧道,将 docker 注册表端口转发到您的本地主机:

vagrant ssh -L5000:localhost:5000 -L8080:localhost:8080 -L80:localhost:80

只要您需要对这些 docker 容器的端口进行网络访问,就可以打开该 ssh 会话。

当这些端口转发隧道打开时,您转发的端口将在localhost(即 127.0.0.1)上可用。您无需像以前尝试过的那样通过其他 IP 地址访问它们。例如,这将允许您通过访问http://localhost/访问在 docker 容器中运行的 Web 服务器,或者通过使用浏览器或其他 HTTP访问http://localhost:8080/访问在端口 8080 上运行的应用程序服务器客户端,例如 curl。在这种情况下,端口 5000 可能没有用,因为可以访问注册表的 docker 命令行实用程序当前不在 Windows 或 OSX 上本地运行。要使用您的私有 docker 注册表,请在您的 CoreOS Vagrant VM 上运行类似的内容:

docker tag eb62f9df0657 localhost:5000/myimage
docker push localhost:5000/myimage
