Question

我已设置在vagrant VM中运行的coreos。我想设置私人码头注册表。我拉了注册表，我可以运行它。以下是运行注册表

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？

Answer 1

我可以看到你正在尝试做的两个问题。

您无法从主机操作系统访问在Vagrant VM中运行的docker容器。
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镜像（库/注册表）不提供此功能。

第1项：请注意，您运行的私有docker注册表未提供管理Web UI。它在端口5000上提供的服务不是网站;它由命令行docker用于在私有注册表中推送和提取图像。如果您需要管理员Web UI，您可以考虑运行其他服务，例如https://github.com/atc-/docker-registry-web（我没有尝试但看起来很有希望）。

项目2：如果您想从Vagrant VM的主机操作系统（可能是Windows或OSX）访问Vagrant-VM托管的docker容器的端口，因为如果您的主机操作系统是Linux，您可能不会不需要Vagrant，然后我建议你打开一个ssh隧道到你的CoreOS Vagrant VM，将docker注册表端口转发到你的本地主机：

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，请保持ssh会话处于打开状态。

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。您无需像之前尝试过的那样通过其他IP地址访问它们。这样，您可以访问http://localhost/或在端口8080上运行的应用程序服务器，通过访问http://localhost:8080/浏览器或其他HTTP客户端（如curl）来访问在docker容器中运行的Web服务器。端口5000在此上下文中可能无用，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上本机运行。要使用私有docker注册表，请在CoreOS Vagrant VM上运行类似的内容：

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