Port forwarding in docker-machine?

Question

Since boot2docker is deprecated I\'ve switched to docker-machine but I don\'t know how to open a port from docker-machine. In bo

Answer 1

With recent versions of machine, you can simply do (where default is the name of the machine):

docker-machine ssh default -L 27017:localhost:27017

This is a more temporary solution than the VM configuration change.

Use the following variation to only forward ports in a background process:

docker-machine ssh default -f -N -L 27017:localhost:27017

• -f Requests ssh to go to background just before command execution.
• -N Allow empty command (useful here to forward ports only)
