virtualisation

Today I will just share with you piece of code that I quite often used when I was working with quick spin of machines using Vagrant. It will create 2 VMs for you based on your requirements ( can be more if you modify the code 🙂 )

 

# based on http://stackoverflow.com/a/33789603/2476347
servers=[
  {
    :hostname => "uno",
    :ip => "192.168.100.10",
    :box => "lamudi/centos-7.0",
    :ram => 1024,
    :cpu => 2
  },
  {
    :hostname => "duo",
    :ip => "192.168.100.11",
    :box => "lamudi/centos-7.0",
    :ram => 1024,
    :cpu => 2
  }
]

Vagrant.configure(2) do |config|
    servers.each do |machine|
        config.vm.define machine[:hostname] do |node|
            node.vm.box = machine[:box]
            node.vm.hostname = machine[:hostname]
            node.vm.network "private_network", ip: machine[:ip]
            node.vm.network "public_network", type: "dhcp", bridge: "en0: Wi-Fi (AirPort)"
            node.vm.provider "virtualbox" do |vb|
                vb.customize ["modifyvm", :id, "--memory", machine[:ram]]
              end
            end
          end    
end

 

The code as usual has a lot of potential for upgrade 🙂 if you would have any suggestions please leave comments!
