Unable to reach docker-machine ips


Hello everybody,

I’m new to Docker Business, so I hope to find some help here in the forum.

We want to use docker-machine to run multiple Docker environments on our server.
So we have installed docker-machine on our CentOs server and let our Docker environment run on the machines. As driver for the machines we uses virtualbox.

With the command docker-machine ip i get an ip and i can ping it from the server, but i dont reach the ip from outside the server.

Anyone here who know how I can solve this problem?
