我用 vagrant 和 centos 7 创建了一个迷你集群。我设法安装了 kube-dns 和 heapster，但是当我尝试使用 php-apache 示例测试自动缩放时，它不起作用。

failed to get CPU consumption and request: failed to unmarshall heapster response: invalid character 'E' looking for beginning of value

这很奇怪，因为我可以看到 grafana 的指标和限制。我的 kube-dns 和 heapster 在 kube-system 命名空间中，所以它应该可以工作。

我有 kubernetes 1.2，如果有人可以提供帮助，那就太棒了。

以下是 heapster 的日志：

好的，我找到了解决方案，我的集群有缺陷。我也必须在主人身上安装法兰绒。由于无业游民，使用选项 --iface=eth1 。

我遵循了本指南http://severalnines.com/blog/installing-kubernetes-cluster-minions-centos7-manage-pods-services但他们没有说要在主服务器上安装法兰绒。

现在一切正常。
