Puppet users - Aug 2012 - How can MCollective replace "puppet kick"?

Dear readers,

I was shocked to see that "puppet kick" will be deprecated in 3.0.0
https://projects.puppetlabs.com/issues/15735

How can MCollective replace "puppet kick"?

Hugs,
Sandra

http://projects.puppetlabs.com/projects/mcollective gives a bit more
information on mcollective itself. You don''t actually push configs to
nodes
with it; you have a client which "tells" all machines that matches a
fact
to trigger a puppet run. The puppetd agent plugin is required for this to
work.

MCollective is a service that runs on every node. It constantly polls a 
message queue server for real-time messages and sometimes responds to them 
by performing actions. 

You use a command-line client app to send messages, and you can set filters 
on each message so only certain nodes or groups of nodes will respond to 
them. Every node that matches a message will react simultaneously when the 
message goes out. 

Each node has a set of actions it can run, provided by plugins. The 
"puppetd" plugin lets you control puppet agent, but it''s
better than puppet
kick: It can trigger runs even if puppet agent usually runs via cron 
instead of as a service, it can enable and disable puppet runs, and it can 
fetch last run summaries. MCollective also lets you be smarter about 
triggering runs because it doesn''t limit you to hostnames; you can
filter
by puppet class, facts, etc. 

Does that help?

Absolutely =)

Wow! That is impressive.

I have seen the puppet agent taking ~100MB of ram.

Is MCollective also written in Ruby, and therefore take a lot of ram?

Sandra,

The mcollective agent is written in Ruby, but it''s really tiny.  You
can use the mco controller plugin to view resource utilization over time, and
it''s generally infinitesimal.

Thanks for clearing that out =)

It definitely sounds useful for other things as well, so I will install it 
once I have puppet 3 up and running =)

Is MCollective part of Puppet Enterprise ?

I cannot find documentation that says yea or nay.

mcollective is stand-alone software, it doesn''t actually require
puppet. It''s also free and open source. The only thing you get with PE
is the live management fature in the dashboard, which is essentially a
GUI for mcollective if I''m not mistaken.

cheers,

Walter

You get a good bit more than that - PE sets up the ActiveMQ stuff for you and
handles key setup/exchange, which is fairly difficult to do by hand the first
time if you aren''t familiar with the stuff.  As it is, any PE node you
add to your PE master automatically gets added to your mcollective environment,
which is quite nice.
