Installing python eggs using puppet.

Hi,

I'm looking into using puppet to deploy different python applications to
different servers.

I want to be able to sandbox the different applications using virtenv.
A basic setup would be:

1. create user
2. install the virtual environment for that user
- -> as the user: virtualenv /userdir
3. Install package dependencies.
- -> as the user: easy_install <mypackage>.egg
This should install any dependencies.

Is this possible, or should I just host the basic user environment in my
RCS repository?

Has anyone used puppet to install eggs earlier? Do you have any tips?

kind regards,
Tarjei

I started writing a provider for easy_install a while back but quickly
discovered easy_install can't query installed eggs (there is some work
out there with yolk/egg but nothing solid) which makes it hard to manage
them. Nor is there a good uninstall mechanism.

James;

If you assume that Puppet is solely responsible for installing
modules, you can use easy_install --report to both keep track of which
modules are installed *and* the files it created.

My working hack to date: http://pastebin.com/f4be5c57a

Next, I'd like to get pymod to take a simple:

pymod { "mysql-python": ensure => installed }

Puppet insists on name => "mysql-python", for some reason...

Yours,
Garth.

PS: I'm hooked. I'm spending hours to ensure I don't ever waste five
minutes manually re-doing something I spent five minutes manually
doing the first time. I hate you, Milkman Dan.

PPS: The second edition better have an index.
