Mac OS X + docker-machine + VMware Fusion

sudo /sbin/route -n add -net 172.17.0.0 -netmask 255.255.0.0 -gateway $(docker-machine ip default)

Mac OS X + docker-machine + VirtualBox

provision_docker
relies on being able to ssh to containers. Thus, the ip of the container must be accessible (a route must exist). If your using docker toolbox on OS X + virtualbox containers are not routed to the host. Run the below commands to be add a route to the containers in the guest VM.
/usr/sbin/scutil -w State:/Network/Interface/vboxnet0/IPv4 -t 0
sudo /sbin/route -n add -net 172.17.0.0 -netmask 255.255.0.0 -gateway $(docker-machine ip)
The route does not persist across reboots. To persist the changes edit
/Library/LaunchDaemons/com.docker.route.plist

  Label
  com.docker.route
  ProgramArguments
  
    bash
    -c
    
    /usr/sbin/scutil -w State:/Network/Interface/vboxnet0/IPv4 -t 0;sudo /sbin/route -n add -net 172.17.0.0 -netmask 255.255.0.0 -gateway 192.168.99.100
