我已经按照GCE指南上的CoreOS 。

但看起来我有问题了解用户数据元数据字段是什么，以及如何让我的云configuration文件被读取..

在具有我的cloud-config.yaml文件的目录中，我运行了以下命令：

 gcutil --project=my-proj-704 addinstance --image=projects/coreos-cloud/global/images/coreos- stable-410-0-0-v20140902 --persistent_boot_disk --zone=europe-west1-a --machine_type=n1-standard-1 --metadata_from_file=user-data:cloud-config.yaml --permit_root_ssh aa-gce-thing 

我的cloud-config.yaml看起来像这样…

• Google计算机引擎防火墙和IpTables
• Google Cloud Compute（GCE）使用gcloud不会为SSH创build有效的格式化公钥
• 神秘的Stackdriver使用Google云端平台的HTTP正常运行时间检查错误
• configurationnginx以提供静态文件
• 如何loggingGCP实例的stream量活动？

CoreOS系统没有任何工作，没有任何的挂载，服务等…..

有任何想法吗？

编辑

即使试了一个非常简单的文件…

云configuration

 coreos: etcd: # generate a new token for each unique cluster from https://discovery.etcd.io/new discovery: https://discovery.etcd.io/7cb8b85dea06c5041720 # multi-region and multi-cloud deployments need to use $public_ipv4 addr: $private_ipv4:4001 peer-addr: $private_ipv4:7001 units: - name: etcd.service command: start - name: fleet.service command: start 

没有骰子….
