错误: Facter: GCE元数据请求失败:已达到超时

Question

这是关于GCP计算实例的。我的GCP实例无法从元数据服务器获取GCE metadata &因此，当我通过GCP通过CentOS映像安装Openstack on google cloud (GCP)时，就会得到这个错误。

VM实例是默认网络的一部分，没有防火墙规则。我也可以在外部登录节点，这证明了网络是安全的。

ERROR : Error appeared during Puppet run: 10.142.0.16_compute.pp
Error: Facter: GCE metadata request failed: Timeout was reached

在/var/log/messages中，我反复收到这样的消息：

Answer 1

IIUC，根据这个错误提示：connect: no route to host，尝试使用metadata.google.internal域替换这个IP 169.254.169.254？

从这个文档/etc/resolv.conf中检查元数据请求的部分，并确保您之前为nameserver提供了正确的nameserver文件。你应该根据约翰·汉利的建议检查服务帐户的设置。

“谢谢，”约翰·汉利。参考你的提示和这个问题-- "为什么我不能访问GCP实例的元数据服务器？“的最早答案。
