Puppet users - Sep 2008 - Migrating Gutsy puppet clients to Hardy

Hi all

I''ve been running an excellent puppet setup over the last ten months
with Ubuntu Gutsy clients talking to an Ubuntu Gutsy server. Gutsy
ships with Puppet 0.22.4-2. The time has come however to try and start
supporting Hardy clients and they are running  0.24.4-3. An initial
test run shows significant problems - the main one being that the
newer client doesn''t seem to be able to find sources served our by the
old puppetmaster.

Does anybody have any words of wisdom for somebody like me? Should I
be upgrading the existing server or will that break the old clients?
Do I need to run two servers? Should I just install old clients on
Hardy via gem instead of apt? Am I in for a long hard slog ?

Any comments gratefully received. I''ll try and write up my eventual
solution for the benefit of others.

Ian

the server should be always the latest. only older clients to newer
servers are supported.

maybe pinpoint packages? I would recommend you to use always the same
versions on server and clients. It''s a lot easier!

Some broad guidance - upgrade the server first and then the clients.  In
most cases old client to new server is backward compatible (with some
notable bugs - some of which are documented at
http://reductivelabs.com/trac/puppet/wiki/UPGRADE).

New client and old server on the other hand rarely, if ever, works.

Cheers

Use the same puppet version on all of your clients and server, this will
safe you a lot of pain.

Its fairly easy to rebuild the deb packages with a newer set of code, ( if
someone didn''t do it already).

We are just in the end of the same process. We actually had trouble getting
the gutsy clients working properly with the server being shipped with hardy.
The solution was to run the puppetmaster on hardy as well. I would not say
you are in for a long hard slog. If you want to you just move the
puppetmaster configuration over to a hardy server, and have the clients talk
to this server after they are upgraded. Im not sure this is needed anymore
as we started this process when hardy was in late beta modus. Running two
servers are not really a problem either. You can keep all the configuration
in eg subversion and have the servers in sync.

Like everybody else say. The best way to stay clean of troubles are to run
the same version on the server and the clients.

Dyresen

To everybody who replied to this, many thanks. Everyone''s contribution
was extremely useful.

I setup a VMWare environment to simulate our live environment and have
decided to run a gutsy server for the old clients and a hardy server
for the new.

Just need to find a way within puppet manifests of telling what my
target machine is running (pref without having to explicitly stating).

Thanks again all - was a lot less painful than I expected.

If you install lsb-release, you should be able to get the information
from facter, which will end up in Puppet as a variable you can use a
case statement on.
