docker airflow容器和SFTP服务器之间的RSA密钥配对

我正在尝试使用docker compose，LocalExecutor来执行一些

SFTP

操作

从我的主机上，我可以轻松地连接到SFTP，因为我已经在默认的~/.ssh文件夹中写入了它，并将其与SFTP主机配对。如何在docker容器中执行相同的操作？ 由于我的docker容器和SFTP主机之间没有任何rsa计算机配对，因此我收到了此错误，在SFTP操作员日志中可见：

    Traceback (most recent call last):

在气流连接中，我在连接类型字段中找不到选项SFTP，但我注意到SFTP\u默认连接没有连接类型的条目。我应该也没有自定义的条目，还是应该（可能）使用SSH类型

谢谢你发布这篇文章，因为它可能对其他人有用

我通过创建全新的rsa密钥（在构建时复制到容器中）并将openssh服务器安装到容器中，解决了这个问题。
另一件不可忘记的事情是确保容器和主机中都有相同的Fernet密钥
