我创建了一个带有vagrant和centos 7的迷你集群。我设法安装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,因为我可以看到使用grafana和限制的指标。我的kube-dns和我的heapster在kube-system命名空间中,所以它应该可以工作。
我有kubernetes 1.2,如果有人可以帮助那将是非常棒的。
以下是heapster的日志:

好的,我找到了解决方案,我的群集存在缺陷。我不得不在主人身上安装法兰绒。使用选项--iface = eth1因为流浪。
我遵循了这个指南http://severalnines.com/blog/installing-kubernetes-cluster-minions-centos7-manage-pods-services,但他们没有说要在主人身上安装法兰绒。
现在一切正常。
