Port forwarding in docker-machine?
Since boot2docker is deprecated I've switched to docker-machine but I don't know how to open a port from docker-machine . In boot2docker I could do like this: boot2docker ssh -L 27017:localhost:27017 This would forward port 27017 from VirtualBox to localhost 27017 as long as the SSH connection is open. Note that I'm not looking for a way to open the port permanently in VirtualBox. How can I achieve this with docker-machine ? You can still access the VBoxmanage.exe command from the VirtualBox used by docker machine: VBoxManage controlvm "boot2docker-vm" natpf1 "tcp-port27017,tcp,,27017,,27017";
