Issue #2128 has been updated by Jeff McCune.
# Added options #
These configuration options have been added in this change set.
<pre>
# The fact to use as the node name.

<pre>
# The name of the node.
# The default value is '$certname'.

These configuration settings should probably be better documented. Should this
be a separate ticket, or is documentation part of this ticket?

Feature #2128: Allow arbitrary fact as node_name identifier
https://projects.puppetlabs.com/issues/2128
Author: Bill Bartlett
Status: Merged - Pending Release
Priority: High
Assignee: Nick Lewis
Category: node
Target version: 2.6.x
Affected Puppet version: 0.24.7

Branch:
Currently, the only fact available as a node_name identifier is the hostname.
I would like to have the capability of having any fact be the node_name
identifier.
Use Case:
The reason this discussion came about is EC2. When an EC2 node is brought up,
the hostname is not known. If we were to have a large, auto-scaling
infrastructure, it is currently very difficult (impossible?) to automate
bringing these EC2 nodes into puppet.
One possible solution is to allow any fact as a node_name, and then for each
particular EC2 instance type that one would need scaling (apache, memcache,
mysql all come to mind among many others), the AMI would be customized with a
custom fact. An example could be a fact called "hostclass" that would then be
set to "ec2_apache", "ec2_memcache", or similar. This allows the auto-created
machine, which we would otherwise be unable to differentiate from any other EC2
node, access to puppet in an automated way.
