Installing vagrant

Setting up vagrant

This demo provides a very simple Vagrantfile that creates Consul server nodes

To install vagrant please go to Vagrant

Below Vagrantfile creates:

1 consul server
1 lb server
4 web servers


Vagrant.configure("2") do |config|
  config.vm.box = "suse/sles12sp2"
  config.vm.box_version = "0.0.1"

  config.vm.define "consul-server" do |cs|
    cs.vm.hostname = "consul_server"
    cs.vm.network "private_network", ip: "172.60.60.6"
  end

  config.vm.define "lb" do |lb|
    lb.vm.hostname = "lb"
    lb.vm.network "private_network", ip: "172.60.60.11"
  end

  (1..4).each do |i|
    config.vm.define "web#{i}" do |web|
      web.vm.hostname = "web#{i}"
      web.vm.network "private_network", ip: "172.60.60.2#{i}"
    end
  end

end

Vagrant Consul Demo

To get started, you can start the nodes by just doing:

vagrant up

Once it is finished, you should be able to see the following:

vagrant status # will show status of each server 

Current machine states:
consul-server                         running (virtualbox)
lb                                    running (virtualbox)
web 1 through 4                       running (virtualbox)

At this point the 6 nodes are running and you can SSH in to play with them:

vagrant ssh consul-server  #will let you login to vagrant machine

consul version
Consul v0.7.5
Protocol 2 spoken by default, understands 2 to 3 (agent will automatically use protocol >2 when speaking to compatible agents)
exit

and

vagrant ssh lb

consul version
Consul v0.7.5
Protocol 2 spoken by default, understands 2 to 3 (agent will automatically use protocol >2 when speaking to compatible agents)
exit
