How can login into docker container and/or image?

I have server.

Into that server I have Docker installed and cassandra images.

How can login into that image for view in WinSCP same folders and files?

Thanks for any help

Sorry, I do not know Cassandra. This is not really a WinSCP question.

You better ask this question on Docker or Cassandra related forums/sites. Or maybe at Super User? Plese post a link here, if you do.
