Vagrant - Ansible Provisioning multi-nodes

1 minute read

I am just throwing this out here for my own reference because I seem to always forget how to do this when spinning up multiple nodes within a Vagrant environment and then running the Ansible provisioner only once at the end of all nodes being spun up (parallel execution). :( Not sure why I always forget this but I DO!

So with the above being said here is a Vagrantfile to spin up N number of nodes (5 in this case) for a Mesos/Marathon Cluster which will run the Ansible playbook (playbook.yml) after all nodes are spun up using the Vagrant Ansible provisioner.

Vagrant.configure(2) do |config|
  #Define the number of nodes to spin up
  N = 5

  #Iterate over nodes
  (1..N).each do |node_id|
    nid = (node_id - 1)

    config.vm.define "node#{nid}" do |node|
      node.vm.box = "mrlesmithjr/trusty64"
      node.vm.provider "virtualbox" do |vb|
        vb.memory = "1024"
      end
      node.vm.hostname = "node#{nid}"
      node.vm.network :private_network, ip: "192.168.202.#{200 + nid}"
      node.vm.network :forwarded_port, guest: "5050", host: "505#{nid}"
      node.vm.network :forwarded_port, guest: "8080", host: "808#{nid}"

      if node_id == N
        node.vm.provision "ansible" do |ansible|
          ansible.limit = "all"
          ansible.groups = {
            "zookeeper-nodes" => [
              "node0",
              "node1",
              "node2",
              "node3",
              "node4"
            ],
            "zookeeper-master-nodes" => [
              "node0",
              "node1",
              "node2"
            ],
            "zookeeper-slave-nodes" => [
              "node3",
              "node4"
            ]
          }
          ansible.playbook = "playbook.yml"
        end
      end

    end
  end
end
