Puppet PostgresQL management - postgresql

Question

I am trying to provision an EC2 instance using puppet. In the process I have downloaded the puppetlabs-postgresql module from puppetlabs. Since I'm fairly new to puppet, i do not want to manage my database by creating classes in my site.pp file located in /etc/puppet/manifests/site.pp. Rather I want to have a module call database in /etc/puppet/modules/database.
What I have done so far is create an init.pp file in /etc/puppet/modules/database. Below is the content of my init.pp file :
class database {
# resources
postgresql::globals{'globals':
version => '9.3',
manage_package_repo => true,
encoding => 'UTF8',
locale => 'it_IT.utf8',
}
postgresql::server{'server':
ensure => 'present',
listen_addresses => '*',
manage_firewall => true,
}
postgresql::server::contrib{'contrib':
package_ensure => 'present',
}
}
And then in my /etc/puppet/manifests/site.pp file i have included the database class as below :
node default {
include localusers
include database
}
However i keep getting an error :
Error: Puppet::Parser::AST::Resource failed with error ArgumentError: Invalid resource type postgresql::globals at /etc/puppet.manifests/init.pp:12
Please what is the correct way to make use of the postgresql classes and resources in my own module and create a database in the module as well ?

You're on the right track, but there are a few issues with how you're using the postgresql module. The reason you're getting the Invalid resource type error is that you're trying to use postgresql::globals as a defined type when it's actually a class. You have the same issue with the other two classes you're using. Try this...
class database {
# set global defaults before creating server
class { 'postgresql::globals':
version => '9.3',
manage_package_repo => true,
encoding => 'UTF8',
locale => 'it_IT.utf8',
}->
class { 'postgresql::server':
listen_addresses => '*',
manage_firewall => true,
}
# install the postgresql contrib package
class { 'postgresql::server::contrib':
package_ensure => 'present',
}
# create database with user and default permissions
postgresql::server::db { 'my_awesome_db':
user => 'my_db_user',
password => 'puppetRocks',
}
}
In the reference section of the module documentation, there's a breakdown of the classes and resources (a.k.a. defined types). The postgresql::server::db type that I used is the simplest way to create a database, user, and permissions all at once. There are separate types available for each of those to provide more fine-grained control.
