我正试图使用docker compose，LocalExecutor在docker容器中对气流执行一些SFTP操作。
在我的主机上，我可以很容易地连接到SFTP，因为我已经创建了rsa，将其写入默认的~/.ssh文件夹，并将其与SFTP主机配对。如何在我的docker容器中执行同样的操作？由于我的docker容器和SFTP主机之间没有任何rsa机器配对，我收到了这个错误，在SFTPOperator日志中可见：

在气流连接中，我在Conn Type字段中找不到选项SFTP，但我注意到SFTP_default连接没有Conn Type的条目。我应该也没有自定义的条目吗？还是应该(可能(有SSH类型？
感谢

我通过创建全新的rsa密钥来解决这个问题，这些密钥在构建时复制到容器中，并在容器中安装openssh服务器
另一件不能忘记的事情是确保容器和主机中都有相同的Fernet密钥。
