https://github.com/atmoz/sftp I am trying to set this up for testing and I have attempted to follow the README with no luck. I need to log in with ssh keys but the directions but it keeps asking me for a password. I am not setting a password when the keys get generated.
/home/test/sftp_testing
$ ls
test1.txt test2.txt test3.txt testing4.txt
$ ssh-keygen -t ed25519 -f ssh_host_ed25519_key < /dev/null
$ ssh-keygen -t rsa -b 4096 -f ssh_host_rsa_key < /dev/null
$ ls

So it looks like the instructions were not complete if you want to try to use a key. I was able to get it to work with the following:
docker run \
-v /home/test/sftp_testing/ssh_host_ed25519_key:/etc/ssh/ssh_host_ed25519_key \
-v /home/test/sftp_testing/ssh_host_rsa_key:/etc/ssh/ssh_host_rsa_key \
-v /home/test/sftp_testing/ssh_host_ed25519_key.pub:/home/foo/.ssh/keys/ssh_host_ed25519_key.pub:ro \
-v /home/test/sftp_testing/ssh_host_rsa_key.pub:/home/foo/.ssh/keys/ssh_host_rsa_key.pub:ro \
-v /home/test/sftp_testing/share:/home/foo/share \
-p 9000:22 -d test_thing \
foo::1001
sftp -P 9000 -i /home/testing/sftp_testing/ssh_host_ed25519_key -oStrictHostKeyChecking=no -oUserKnownHostsFile=/dev/null foo@10.0.2.15
