Docker:输出显示为http://192.168.99.100:8000/，而不是http://0.0.0.0:8000/

Question

我刚刚发现"hello world“是在http://192.168.99.100:8000/上打印出来的，而不是http://0.0.0.0:8000/或local:8000。

尽管它正在监听：http://0.0.0.0:8000 (1)。我想知道为什么会发生这种事。有人知道怎么解决这个问题吗？谢谢!

终端输出：

Answer 1

您似乎正在使用docker-machine，因为您的端口公开了IP，这意味着所有docker-ports都会暴露在docker-machine ip的结果中。这是因为所有容器都运行在docker-machine使用的虚拟机中(可能在VirtualBox中作为VM提供者)。

如果您希望将此端口公开给0.0.0.0或本地主机，则需要确保您在VirtualBox VM中转发端口，无论您的扩展底座是什么。这需要在VM网络设置下添加端口。
