Creating a dev environment to compile and run lichess

Create a ubuntu 18.04 virtual machine

Vagrant.configure("2") do |config|
	config.vm.network "forwarded_port", guest: 9663, host: 9663
	config.vm.network "forwarded_port", guest: 9664, host: 9664
	config.vm.network "forwarded_port", guest: 27017, host: 27017
	config.vm.define "bionic64" do |bionic64|
		bionic64.vm.box = "ubuntu/bionic64"
		bionic64.vm.hostname = "bionic64"
		bionic64.disksize.size = "20GB"
		bionic64.vm.provider "virtualbox" do |v|
			v.memory = 12288
			v.cpus = 4
			v.name = "bionic64"
		end
	end
end
