= 3 nodos vagrant + docker
{{tag>Vagrantfile}}

la idea es desplegar un cluster swarm
<sxh ruby; title: 3 nodos vagrant>
Vagrant.configure("2") do |config|
   config.vm.define "nodo1" do |nodo1|
     nodo1.vm.box = "debian/jessie64"
     nodo1.vm.hostname = "nodo1"
#     nodo1.vm.network "public_network", bridge: "eth0"
     nodo1.vm.network "private_network", ip: "10.0.100.101"
     nodo1.vm.provision "shell", path: "install-docker.sh"                                                                                                                                                         
     nodo1.vm.provider "virtualbox" do |vb|
       vb.name = "debian-swarm-nodo1"
       vb.memory = 1024
       vb.cpus = 1 
       vb.linked_clone = true    
     end 
   end 
   config.vm.define "nodo2" do |nodo2|
     nodo2.vm.box = "debian/jessie64"
