Connecting Puppet Agent with Puppet Master

Before Puppet Agent can connect to Puppet Master, it has to find out the host name of the Puppet Master and that host name must resolve an IP address that belongs to the Puppet Master node. Our Puppet Master is currently configured to acquire an IP address from DHCP server. This is not ideal because if the IP address changes on the Puppet Master node, we have to reconfigure Puppet Agents to make the connection to Puppet Master work again. To avoid this problem, it is good practice to configure Puppet Master with a static IP address.

We will also create a new environment on the Puppet Master node and configure Agent nodes to join this environment. As we have to do couple of tweaks on the Puppet Master node as well as on the Puppet Agent nodes, I feel that it's best that we consolidate all the bootstrap logic in a new Puppet module, which we'll call the bootstrap.
