Issue #2128 has been updated by Jeff McCune.

# 0.24.8 Question #

Again, on site with a customer they are considering applying this patch before 
release to abandon their custom modifications to Puppet.  The question came up:

Does this change set affect the behavior of 0.24.8 clients?

I don't think it does since it's using the REST API code path rather than the 
XMLRPC code path, but I'd like to double check before I say "No"

A "We don't think so" is a good enough answer as long as it's reasonably 
confident.  We'll be testing the 0.24.8 clients against the patched 2.6.8.

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
Keywords: 
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.
