无法在OpenStack中启动Kubernetes集群

Question

我正在尝试使用-> http://kubernetes.io/docs/getting-started-guides/openstack-heat/中提到的步骤在OpenStack中启动Kubernetes集群

命令KUBERNETES_PROVIDER=openstack-heat ./cluster/kube-up.sh失败，并显示以下消息：

... Starting cluster using provider: openstack-heat
... calling verify-prereqs
swift client installed
glance client installed
nova client installed
heat client installed
openstack client installed
... calling kube-up
kube-up for provider openstack-heat

最后一行对于kube-up.sh命令的不同执行是不同的。我注意到这与/cluster/openstack-heat/kubernetes-heat/kubecluster.yaml中存在的yaml和sh文件相对应。在本例中，它是./cluster/openstack-heat/kubernetes-heat/fragments/configure-salt.yaml

由于某些原因，它无法将这些文件的内容合并到kubecluster.yaml中。

有什么想法吗？
