I’m able to connect in SSH to docker client with credentials (docker/tcuser).
But if my laptop passed in hibernation mode, I loose the ssh connection and I’m unable to connect again to docker client. Even after a restart of VM.
The only solution is to restart my laptop.
My environment : Windows 8 / docker toolbox / docker client 1.8.3 / Putty
Try using docker ps to find the container. If it does not appear, it may have crashed. Containers expire once their processes stop. You can see expired containers with docker ps -a.
I must point out that ssh into a container is a bit perverse. Try docker exec -it container_name /bin/bash if you want a shell inside a container.
