This demo provides a very simple Vagrantfile that creates two nodes,
one at "172.20.20.10" and another at "172.20.20.11". Both are running
a standard Ubuntu 12.04 distribution, with Serf pre-installed under/usr/bin/serf.
To get started, you can start the cluster by just doing:
$ vagrant up
Once it is finished, you should be able to see the following:
$ vagrant status
Current machine states:
n1 running (vmware_fusion)
n2 running (vmware_fusion)
At this point the two nodes are running and you can SSH in to play with them:
$ vagrant ssh n1
...
$ vagrant ssh n2
...
To learn more about starting serf, joining nodes and interacting with the agent,
checkout the getting started guide.
