# Network docker containers tricks

If you host Docker on a Virtual Machine (a Vagrant managed VM for instance, or the common boot2Docker you have in MAC OSx or Windows systems), you can make docker containers reachable from your VM's host by routing request to the virtual machine that's running docker.

NOTE: you should have your virtual machine configured as `bridged network`.

Linux

  > ip route [add|replace] <INTERNAL_IP_DOCKER> via <BRIDGE_DOCKER_VM_IP> dev <INTERFACE>

  > sudo ip route add 172.17.0.0/24 via <dockers vm IP> dev eth1

MacOSx

  > route [add|change] -net -ifscope <INTERFACE> <DOCKER_IP_IN_VM_MASK> <BRIDGE_DOCKER_VM_IP>

  > sudo route add -net -ifscope en1 172.17.0.0/24 <dockers vm IP>
