【问题描述】：
我正在运行 docker 容器，作为一项工作的一部分，我必须 ssh 进入远程主机并在远程主机中执行一些命令。 我遵循以下方法。
- 已启动 Jenkins 容器并且运行良好
- 检查我是否能够 ping 远程实例并且它工作正常。我也可以使用密码 ssh。
- 现在我已经在 docker 容器中生成了公钥和私钥，并将公钥推送到远程主机的 authorized_keys 中。
- 当我尝试使用无密码 SSH 时，它会使用密码方法。
以下是调试模式的输出 -

不确定我缺少什么，因为我在从 docker 主机到远程机器进行无密码 SSH 时遵循完全相同的方法，并且工作正常。
任何帮助表示赞赏，非常感谢。
【问题讨论】：
-
您确定服务器支持 RSA 密钥吗？
-
如果您在谈论 Docker 主机或远程服务器，请告诉我，仅供参考，我可以在 Docker 主机和远程服务器之间进行无密码 ssh。
