I have an RHEL 7.2 server, and I tried to run docker-machine create command against it but failed.
docker-machine create --driver generic --generic-ip-address … --generic-ssh-key ~/.ssh/id_rsa vm
The failure message says “OS type can not be recognized”, but I also noticed that it blocked for a long time when "Waiting for SSH to be available"
Why it’s so difficult to provision docker engine to private hosted server?
Is it a problem of SSH or OS type parser?
