I’m unable to docker-compose successfully on a remote host using SSH from a gitlab CI/CD pipeline runner.
docker-compose fails with the following errors :
http.client.RemoteDisconnected: Remote end closed connection without response
urllib3.exceptions.ProtocolError: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response'))
requests.exceptions.ConnectionError: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response'))
docker.errors.DockerException: Error while fetching server API version: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response'))
I’m not able to repro the issue outside Gitlab. Meaning, I tried on my local machine by running the same docker image my gitlab deploy step use, do the exact same commands in my script manually and it worked like a charm…
I’m even trying the ssh config in the script by connecting to the host and printing docker version
and it succeeds properly.

echo "$SSH_PRIVATE_KEY" | ssh-add -
