I want to use docker machine with a remote server docker daemon through ssh so no need to open 2376 port in the remote server.
Local Host:
$ docker-machine create --driver generic --generic-ip-address [IP_Address] --generic-engine-port 2376 --generic-ssh-key ~/.ssh/id_rsa --generic-ssh-user root [Host]
Remote host:
$ docker daemon -H tcp://127.0.0.1:2376
Result of executing the Local Host command:
$ docker-machine create --driver generic --generic-ip-address [IP_Address] --generic-engine-port 2376 --generic-ssh-key ~/.ssh/id_rsa --generic-ssh-user root [Host]
...
Cannot connect to the Docker daemon. Is the docker daemon running on this host?
As per nmap remote port 2376 is closed, so the error makes sense.
I have tried tunneling through ssh by executing the following in my local host:
$ ssh -L 2376:127.0.0.1:2376 [Remote_Host]
** Note docker machine is trying to reach docker daemon in the remote host, so the tunnel is useful **
I thought maybe using ssh -R or a combination of both would work but I have not been able to make it work yet, do you have any idea or workaround to make this work?
Do not hesitate to bring me to a completely different approach to solve this.
Thanks in advance.
