在CoreOS安装中服务失败

Question

我有以下问题，安装和提供基于Kubernetes CoreOS-libvirt的集群。

当我在主节点上登录时，我会看到以下内容：

ssh core@192.168.10.1
Last login: Thu Dec 10 17:19:21 2015 from 192.168.10.254
CoreOS alpha (884.0.0)
Update Strategy: No Reboots
Failed Units: 1
  kube-addons.service

尝试调试它时，我运行并接收以下内容：

core@kubernetes-master ~ $ systemctl status kube-addons.service
● kube-addons.service - Kubernetes addons
   Loaded: loaded (/etc/systemd/system/kube-addons.service; disabled; vendor preset: disabled)

我的版本是：

etcd --version
etcd version 0.4.9

但我也有一个etcd2：

etcd2 --version
etcd Version: 2.2.2
Git SHA: b4bddf6 
Go Version: go1.4.3
Go OS/Arch: linux/amd64

目前，第二个正在运行：

ps aux | grep etcd 
etcd       731  0.5  8.4 329788 42436 ?        Ssl  16:40   0:16 /usr/bin/etcd2

是什么引起了这个问题，我该如何解决？

谢谢。

相关的日志线是：

/opt/kubernetes/addons/skydns-svc.yaml": error validating data: found invalid field portalIP for v1.ServiceSpec; if you choose to ignore these errors, turn validation off with --validate=false

您应该找出IP的无效之处，或者将标志设置为忽略。
