我创建了一个带有Vagrant和Centos 7的迷你群集。我设法安装了Kube-DNS和HEAPSTER，但是当我尝试使用PHP-Apache示例测试AutoScale时，它无效。<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
failed to get CPU consumption and request: failed to unmarshall heapster response: invalid character 'E' looking for beginning of value
这很奇怪，因为我可以看到带有Grafana和极限的指标。我的kube-dns和我的堆位于kube-system命名空间中，因此应该起作用。
我有Kubernetes 1.2，如果有人可以提供帮助。
这是堆的日志：

好吧，我找到了解决方案，我的群集有缺陷。我也必须在主人上安装法兰绒。使用选项-iface = eth1，因为Vagrant。
我遵循本指南http://severalnines.com/blog/installing-kubernetes-cluster-minions-centos7-manage-pods-services，但他们没有说要在师父上安装法兰绒。
现在一切都在起作用。
