please describe your container in more detail.
How do you start it.
Does your container show any thing under the column PORTS
like: 0.0.0.0:1880->1880/tcp
that would mean you can use the host address with the ports mentioned before the ->
If those entries don't exist then you need to keep your containers, it will reuse the address until the container is removed.

You need to run you container with -p so ports are forwarded or possibly expose them in the dockerfile

ok it was me.
my ftp server shows following port under docker ps
0.0.0.0:2121->2121/tcp, 0.0.0.0:2222->22/tcp
and i can start user_name_in_sftp@my_conti
then i login to sftp server. is it a way to login without sending port 2222 ? i can not use port 22 in my docker-compose.
when i say ports "22:22" in my docker-compose. docker failed
failed : Error starting userland proxy: listen tcp 0.0.0.0:22: bind: address already in use

i can login to sftp server via ssh (with user i created under create image)
i login with my user (or with docker exec -it "sftp_server" /bin/bash) and say
sudo useradd -d /upload -G sftp upload -s /usr/sbin/nologin
and add password for upload user echo "upload:opload123" | sudo chpasswd
/upload is in my docker-compose as volumes then i say sudo chown upload:sftp -R /upload
i can't sftp to my container
i say sftp upload@container-ip it ask for password i write password
failed Permission denied, please try again.
can you see what it's wrong what i missing?

I try following in filezila:
sftp://container-ip. "username". "password" port=2222
answer: fzSftp started, protocol_version=8
command : open "user-name@container-ip" 2222
command: Pass: *********
Failed: Server unexpectedly closed network connection
Failed: Can not connect to server
sftp://container-ip. "username". "password" port=2222
answer: fzSftp started, protocol_version=8
command : open "user-name@container-ip" 2222
command: Pass: *********
Failed: Server unexpectedly closed network connection
Failed: Can not connect to server
try: container-ip:2222. "usernane" etc.
(convention is hostname:portnumber or hostname:portname in the host field to use another port.
or ithas a separate option like sft -p
