Toggle noop mode from puppet dashboard

[Kenneth Holter]

Hi all,

I'd like to have most/all my puppet clients running in noop mode, and
use Puppet Dashboard to toggle the noop switch for ordinary runs. I
have groups of servers defined in the console, so toggling the noop
switch on these groups would allow be great.

Have anyone implemented such a feature and would like to provide a quick howto?

One way might be to run puppet in cron, and have puppet control the
cron command. If a dashboard variable "noop_mode" was set for the
node, then the cron command would be something like "puppet agent
--noop", and if not set the command would run without noop switch
(i.e. "puppet agent"). But this means we would need to run puppet
agents from cron intead of in daemon mode, and I'm not sure which is
best.

Regards,
Kenneth

We default to --noop in production (as set in the puppet.conf file) then
either manually override this on the command line or use mcollective to
do grouped no-noop runs across our infrastructure. We modified the
standard mc-puppetd to add support for this and tag specifications so we
can do partial config runs under central control as well. I'm not sure
how easy this would be to hook into the dashboard, but mcollective might
be an approach to look at.

There was a Redmine issue on this awhile back that was improperly rejected. I've reopened it.
