Puppet users - Jul 2006 - Minimal Kickstart setups to use with Puppet

Hi,

I was at the Puppet talk at Oscon and I would like to try using
Puppet for PXE on RHEL machines and I was wondering if there are
standard minimal Kickstart recipes  from which Puppet can then take
over.

Thanks,

I''d suggest running system-config-kickstart to generate what you want
or
otherwise taking a minimal install you''ve already done and using
/root/anaconda.ks that Anaconda saves as a starting point.

You can do whatever you want in %post, including installing puppet and
invoking it (say in local context).

Assuming this is to be tied into PXE infrastructure and you want to do
any system specific templating in that post action (i.e. deploy this
recipe there, but not here), I happen to have a tool for that...
http://et.redhat.com/page/Cobbler_%26_Koan_Provisioning_Tools (shameless
plug -- let me know if you encounter any issues or have improvement ideas).

For any advanced kickstart questions, try joining
kickstart-list at redhat.com -- I am by no means an expert and usually rely
on s-c-k and the "hack the file in /root" method.

Hi Jason,

I wrote a blog entry that outlines what needs to be done to provision
puppet[1] - feel free to contact me to work this out in more detail. I
have a sneaking suspicion that the entry is somewhat out of date, since
puppet is now in Fedora Extras.

I''d love to have standard scripts for installing Puppet on most
standard platforms.  Red Hat, Debian, and Solaris should be pretty
easy to accommodate.

I can create a separate section for this documentation or something,
but it seems like there should be a better way.

Attached is a kickstart config that installs puppet, enables puppetd to
start after reboot, and tries to connect to the puppetmaster just enough
to get the client certificate during installation. Comments more than
welcome.

I use it to provision Xen virtual machines quite happily.

Hi David,

Thanks for the KickStart configs, I''m going to give them a shot this
week. Just wanted to let you know I haven''t forgotten!
