Creating Cluster of Vagrant Machines

CLUSTER OF VAGRANT MACHINE

Setting up a cluster with one vagrant file:

Make sure you have a virtualbox installed in your machine by the command:

vboxmanage –version

If it is not installed then install it with the following command:
sudo apt-get install virtualbox

Make sure you have a vagrant installed in your machine by the command:

vagrant –version

If it is not installed then install it with the following command:

sudo apt-get install vagrant



Create a file named Vagrantfile in the empty directory of your choice having the following code in it:

Vagrant.configure("2") do |config|

    # Number of nodes to provision

    numNodes = 4

    # IP Address Base for private network

    ipAddrPrefix = "192.168.56.10"

    # Define Number of RAM for each node

    config.vm.provider "virtualbox" do |v|

        v.customize ["modifyvm", :id, "--memory", 1024]

    end

    # Download the initial box from this url

    config.vm.box_url = "http://files.vagrantup.com/precise64.box"

    # Provision Config for each of the nodes

    1.upto(numNodes) do |num|

        nodeName = ("node" + num.to_s).to_sym

        config.vm.define nodeName do |node|

            node.vm.box = "precise32"

            node.vm.network :private_network, ip: ipAddrPrefix + num.to_s

            node.vm.provider "virtualbox" do |v|

                v.name = "Couchbase Server Node " + num.to_s

            end

        end

    end

end

Then run the command vagrant up to up the cluster! This will setup 4 node cluster for you.
