无法从Kubernetes容器访问互联网
我正在使用Mac OSX上的Vagrant Kubernetes 0.9.3安装程序。
环境：
- Kubernetes 0.9.3
- stream浪1.7.2
- VirtualBox的-4.3.20-96996-OSX
我能够成功部署映像并在一个单一的小型环境中启动容器：
主
奴才-1
我无法从正在运行的容器中访问Internet。 我可以从minion-1机器访问互联网。
我使用Vagrant设置环境
/kubernetes$ export KUBERNETES_PROVIDER=vagrant /kubernetes$ vagrant up …（初始化日志和Virtualbox中master + minion-1的成功设置）
ssh进入minion-1机器，以确保互联网连接
/kubernetes$ vagrant ssh minion-1 [vagrant@kubernetes-minion-1 ~]$ ping google.com PING google.com (173.194.123.37) 56(84) bytes of data. 64 bytes from lga15s47-in-f5.1e100.net (173.194.123.37): icmp_seq=1 ttl=63 time=89.3 ms
以前是成功的连接
下面你可以看到容器似乎无法访问互联网。

这是一个stream浪者安装问题，或者是在Kubernetes框架这是故意的？ 如果是这样，访问互联网的正确方法是什么？
这不是故意的。 容器应该能够看到外部的互联网。 我的猜测是，您的Vagrantnetworking设置有问题，可能是由于您的主机防火墙来自容器IP的数据包。
