Static IP on Public Network/Bridged

[James Jelinek]

Here is a very basic Vagrantfile that I'm using to boot a web and db server which I plan to setup nginx/rails and mysql.

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure("2") do |config|
config.vm.define :web do |web|
web.vm.box = "web"
web.vm.hostname = "web"
web.vm.network :public_network, ip: "192.168.1.200"
end

config.vm.define :db do |db|
db.vm.box = "precise32"
db.vm.hostname = "db"
db.vm.network :public_network, ip: "192.168.1.201"
end
end


I want to assign a static IP to the interface instead of having dhclient pull one. I've read the documentation and this seems to be the way to do it but each time I boot the VMs they grab an IP from the dhcp pool of my router instead of the IPs I've specified.

Am I doing something wrong here?

Hi James, 

One thing I've noticed with my them machines is that on my host only networks the static IP is there and works (ie ssh and other services) *even though* ifconfig reports the dhcp address.  After restarting the interface it reports correctly as well.

I am running into the same issue. Looks like Vagrant assumes that a
bridge interface use DHCP. on my Ubuntu Guest, it appends the
following block in /etc/network/interface

auto eth2
iface eth2 inet dhcp

I want to use static IP and could not figure out a way to do it under vagrant.
I hate to have to resort to VBoxManage to configure networking and
start/stop vm.

Is there any way to override vagrant's network config on bridge interface?


thanks,
Wei

It is not possible to assign a static IP for bridged\public interfaces in the Vagrantfile. You can set the MAC address in the Vagrantfile and then set your hypervisor's dhcp server (or if you use a different dhcp server) to recognize that MAC address and assign a specific IP of your choosing.

I do not know how to do this for Virtualbox, but there are write-ups online if you search Google.

in my vagrantfile i use

config.vm.network "public_network", bridge: 'eth1', ip: "192.168.0.104"

to set static ip from my server
