Puppet users - Dec 2013 - using mco to manage puppet resources by class

Has anyone successfully use the class selectors for the puppet MCollective
plugin?

Something like:

$ mco puppet runonce --tags mysql::master

From the docs:
*puppet_tags*
*===========*

*Validates that a comma seperated list of tags are valid Puppet class names*

*      Author: R.I.Pienaar <rip@devco.net <rip@devco.net>>*
*     Version: 1.0*
*     License: ASL 2.0*
*     Timeout: 1*
*   Home Page: http://devco.net/ <http://devco.net/>*

*   Puppet tags can be a comma seperated list of valid class names, for
details*
*   about valid class names please see the puppet_variable validator
documentation.*

*   An example of 2 tags would be:*

*       apache,mysql::master*


When I run that command, even though that class is only applied to a single
host, the list it compiles is all 43 of the hosts currently under mco
control:

$ mco puppet runonce --noop --tags mysql::master

 * [ ============================================================> ] 43 / 43




Finished processing 43 / 43 hosts in 3720.64 ms

I''ve tried several variations and classes without success.  It always
processes the list of all servers.

Hi,

I haven''t played with mco, but doesn''t the document you quote
say
"puppet_tags" instead of just "tags"?

I assume the parameter should be --puppet_tags=mysql::master.

HTH,
Felix

Hi,
 
mco puppet --help 
says the following for tags;
       --tags, --tag TAG            Restrict the run to specific tags
 
>>mco puppet runonce --noop --tags mysql::master
So, it would be correct that this runs over all puppet nodes, except the 
Puppet run will only process mysql::master.
--tags doesn''t act as a node filter for MCollective.
 
If you want to filter you puppet run to nodes, only having the class 
mysql::master, use this filter;
   -C, --wc, --with-class CLASS     Match hosts with a certain config 
management class
 
mco puppet runonce --noop --wc mysql::master
