Creating clusters of Vagrant machines

While the scenario of mimicking defined application architectures (for example, the two-tier or three-tier web application) can be accomplished using simple hosts files and hosts file modifications, creating clusters of Vagrant machines will require a bit of additional complexity, namely, the ability for machines to discover one another using either DNS servers or through service discovery.

In this example, we will create a cluster of Vagrant machines that can communicate with DNS connections using two additional tools:

  • Consul (https://consul.io): This is a tool that allows services and machines to discover one another over a distributed network. In our case, we will use Consul very simply and set up a single ...
