Provisioning PosgreSQL with Puppet on Vagrant

I've got a puppet manifest that resists my attempts to get it working right, given I'm no expert on the puppet DSL, and I'm fairly new to Puppet, I haven't managed to figure this out.

I'm trying to install Postgres using puppetlabs posgres module, creating a default role, and fixing up the DBs to work on UTF8.

Everything runs and installs, but the role doesn't get created. But if I run the provision again, then the role gets created. I assume perhaps has to do with the execution order, but honestly I'm lost ... (more)

Lol - you're creating a role, then dropping the entire cluster and recreating it in the exec .... erm. Yes, you have a massive ordering issue :-). Read the man page for pg_dropcluster.

also why don't you let the postgresql module handle the installation of the packages ?

Because that's what triggers the DB being created in ASCII encoding, that's what I was doing at first, but due to the bug on puppet, this is the ...(more)

Try running your puppet module with debug, it may give additional insight to what is happening.

puppet apply foo --debug

One possible issue I see is that you are making a user called 'user_vagrant'. I assume you actually just want to make sure the vagrant user exits, not make a new user.

You have:

user { "user_vagrant":
  ensure => "present",
}

I assume you want

user { 'vagrant':
  ensure => "present",
}

Also, I recommend that you make sure you have the latest version of puppet, (3.x).

right about that, I changed it so many times, I made a mistake last time I added it.

I spun up a vagrant mahcine (precise64) to test this out. The Puppet code is all solid. As far as I can tell the problem is the arrow chaining the vagrant role to the exec. The exec is not firing in my test suite, probably because the unless condition is not being satisfied. When I comment out the exec or remove the arrow chaining syntax the vagrant role is created.

puppet apply --test pg.pp

Finally found the right approach to fix both the applied order, and the UTF8 issue which forced me to try the "pg_dropcluster" to begin with. Btw, this is a known issue here's the issue url http://projects.puppetlabs.com/issues/4695

This is the whole file I use to install PostgreSQL 9.1 with UTF8, and RVM ruby. Hope this helps.

Modules:
- puppetlabs/apt - 1.4
- puppetlabs/concat - 1.0
- puppetlabs/stdlib - 4.1.0
- puppetlabs/postgresql - 3.2
- blt04/puppet-rvm - git://github.com/blt04/puppet-rvm.git

stage { 'pre':
  before => Stage['main']
}

class pre_req {
  user { "vagrant":
    ensure => "present",
  }

  exec ...
