ssh into container immediately closes the connection

[mpodber1971]

i ran this command from the instance where docker resides: sudo docker run -d -p 2222:22
-v /var/run/docker.sock:/var/run/docker.sock
-e CONTAINER=matt -e AUTH_MECHANISM=noAuth
jeroenpeeters/docker-ssh

i run the ssh command to the instance: ssh -p 2222 -i <KEY_LOCATION> user@ipaddress

and get the following dialogue before it closes the connection immediately

###############################################################

Docker SSH ~ Because every container should be accessible

###############################################################

container | matt

###############################################################

Connection to XX.XXX.XX.XXX closed by remote host. Connection to XX.XXX.XX.XXX closed.

does the sshd service need to be running on the container?

Are you running Docker on Windows? If so check #7.

Had a similar issue today and it turned out to be a typo and permissions on the /var/run/docker.sock and in your case it could be permissions too. Try changing the volume flag to:

-v /var/run/docker.sock:/var/run/docker.sock:Z

That should setup SELinux permissions correctly if that happens to be the issue.

I have the same issue on ubuntu the client and on the server and logs return:

                        ^

@mgomma i had the same issue, building the dockerfile in this git repository again resolved the issue

Also i had to quote this with single quotes FILTERS={\"name\":[\"^/my-container$\"]}

The full command

docker run -e 'FILTERS={\"name\":[\"^/my-container$\"]}' -e AUTH_MECHANISM=simpleAuth -e AUTH_USER=sshd -e AUTH_PASSWORD=1234 --name sshd -p 2222:22 --rm -v /var/run/docker.sock:/var/run/docker.sock docker-ssh

Note during the build i encountered the following warnings:

hi all, i got this kind of error too.

I forget that to installed the "bash" into the objective container, eg. in alpine image, "apk add bash".
