Puppet Dashboard Groups

[kaustubh chaudhari]

Hi,

I was looking for a way to group the servers dynamically. Eg: create a "Windows" Group and all the existing nodes and new nodes should be part of "Windows" group.
I edit a group and then add each server, but practically its not possible with 2k servers in all!!

Is there a way to do that?

Don't know about this but how about making use of the provided rake tasks, like;
rake nodegroup:add                             # Add a new node group
rake nodegroup:add_all_nodes                   # Automatically adds all nodes to a group
rake node:addgroup                             # Add group(s) to a node

Thanks for the Reply Stefan!

I did looked into these options, but i dint find a way to add only windows systems to windows group and linux system to linux group.

Do you have MCollective running?

You could use this to generate a list based on specified facts (mco find --wf <fact>) to use in those rake tasks.

Or create them by hand from the Inventory Search in the Dashboard, maybe even a custom rake task.

Hi Stefan,

I am in process of setting up MCollective!

In the mean while i can do the search using inventory search in Dashboard, i do get the list, but when i try ti export the details in the cvs format, it wont export only filtered, it will export all the node list ie: all linux windows etc.

where i an searching with the facts as osfamily = windows  and/or Linux.

>>it will export all the node list

That's not nice :(

So that will really be by hand; copy/paste & strip hostnames.

What about storing the facts in yaml format in the puppetmaster and just doing a grep there?

[Richard Berwald]

I recently faced the same challenge. I did not want to group by osfamily but by another fact.

I came up with this solution:

1) retrieve a list from PuppetDB in format 'nodename:factvalue' for all nodes using puppetdbquery on a puppetmaster (sudo puppet query facts --facts=<factname> "<some query that resolved to true>")

2) retrieve the group list from the console with 'rake nodegroup:list'

3) Compare the existing groups with the groups based upon the values from the fact and create missing groups with 'nodegroup:add[groupname]

4) For each (already) existing group, get all members of the group with 'nodegroup:group_list[groupname]'

5) Compare the nodenames that are already in the group with the list of nodenames from PuppetDB, and add missing nodes of a group with node:group[nodename,<standardgroup>:<groupname>]

I came to this solution because rake calls felt relatively slow (about 7 seconds per call) on our platform and I wanted it to be able to potentially scale to thousands of nodes.

This runs once a night from an old fashioned cron.
