Question

实例：1 主机名：hdp-node-1 ip地址：35.200.132.198

实例：2 主机名：hdp-node-2 ip地址：35.200.208.150

我可以从本地计算机登录两个实例。但是我想在谷歌云平台的这两个实例之间使用公共私钥对设置无密码的SSH，我已经在节点1上创建了RSA密钥，但是当我尝试ssh-copy-id时，它给出的权限被拒绝了我也还检查了文件夹权限。

>>> 'C' in [x for i in my_dict.values() for x in i]
True

调试日志

如果安装由平台管理的project wide keys或instance only公钥，则更加容易。安装在每个实例上的GCE代理将为您复制元数据中的实例。即使您动态创建新节点，该解决方案也将起作用。
