Create a way to automatically collect hosts for unicast cluster about puppet-elasticsearch

[electrical]

Relevant config part: http://pastebin.com/QSWkMAau

Create a define 'node' that exports the required information so it can be collected and put in the config file.

Would be great addition to this module.

If anyone is interested in how we go about this right now - we query the information from our PuppetDB installation using these: https://github.com/dalen/puppet-puppetdbquery

I'm currently trying to build a library which allows for collecting variables and then fetch those as an array, which i then hopefully can use in the config variable for the node list.
Otherwise i would need to do some file concat solution.

[electrical]

I'm pretty far with this now.
Went for a sort if file / variable concat variant.
It seems to be working pretty good for now.
In the meantime i also found an other bug in the current config file generator ( fixed now ) which didn't print arrays :-(

There are still a few issues with this feature and won't make it into master for a while i think.
The biggest problem is merging the configuration hashes together.
Found some solutions but needs to be fully tested.

First preview of some generated code:

## GENERATED BY PUPPET ##
---
cluster:
  name: somename
  routing:
    allocation:
      awareness:
        attributes: rack
discovery:
  zen:
    ping:
      unicast:
        hosts:
             - address_host1
             - address_host2

[electrical]

Seems i got lucky :-)
I'm able to collect different nodes and add them to the whole config_hash and make it work as expected.
Nicely added feature is that we can write up the keys in a shorter way. see issue #11

[electrical]

Need to write some tests for this feature and then i can implement it. stay tuned :-)

[electrical]

Sorry for lack of updates on this. Just came back from vacation.
I haven't been able yet to write the testing stuff for this so its not implemented yet.

Not sure if you have any input w/ the actual folks working on elastic search, but the ability to just do a DNS SVR lookup to specify the hosts would make this whole thing much easier! the AWS pluign requires more access than I'd like, but a simple DNS solution would be great.

[electrical]

I've decided to drop this feature.
When i started with this i thought all hosts had to be listed but learned a while ago that was not required.
managing a small list of hosts should be fairly easy.

Closing.
