postgresql: types/providers for postgresql files for Puppet

This module provides a new type/provider for Puppet to read and modify postgresql config files using the Augeas configuration library.

The advantage of using Augeas over the default Puppet parsedfile implementations is that Augeas will go to great lengths to preserve file formatting and comments, while also failing safely when needed.

This provider will hide all of the Augeas commands etc., you don't need to know anything about Augeas to make use of it.

Requirements

Ensure both Augeas and ruby-augeas 0.3.0+ bindings are installed and working as normal.

See Puppet/Augeas pre-requisites.

Installing

On Puppet 2.7.14+, the module can be installed easily (documentation):

puppet module install puppet/augeasproviders_postgresql

You may see an error similar to this on Puppet 2.x (#13858):

Error 400 on SERVER: Puppet::Parser::AST::Resource failed with error ArgumentError: Invalid resource type `pg_hba` at ...

Ensure the module is present in your puppetmaster's own environment (it doesn't have to use it) and that the master has pluginsync enabled. Run the agent on the puppetmaster to cause the custom types to be synced to its local libdir (puppet master --configprint libdir) and then restart the puppetmaster so it loads them.

Composite namevars

This type supports composite namevars in order to easily specify the entry you want to manage. The format for composite namevars is:

local to <user> on <database> [in <target>]

if defining a local (socket) rule, or:

<type> to <user> on <database> from <address> [in <target>]

otherwise.

In each form, in <target> is optional. You can also use a personalized namevar and specify all parameters manually.

manage simple local entry

pg_hba { 'local to all on all':
  ensure => present,
  method => 'md5',
  target => '/etc/postgresql/9.1/main/pg_hba.conf',
}

manage simple host entry

pg_hba { 'host to all on all from 192.168.0.1':
  ensure => present,
  method => 'md5',
  target => '/etc/postgresql/9.1/main/pg_hba.conf',
}

multiple users and databases

pg_hba { 'host to user1,user2 on db1,db2 from 192.168.0.1':
  ensure => present,
  method => 'md5',
  target => '/etc/postgresql/9.1/main/pg_hba.conf',
}

pg_hba { 'Allow +foo and @bar to mydb and yourdb':
  ensure   => present,
  user     => ['+foo', '@bar'],
  database => ['mydb', 'yourdb'],
  method   => 'md5',
  target   => '/etc/postgresql/9.1/main/pg_hba.conf',
}

using a personalized namevar

pg_hba { 'Default entry':
  type     => 'local',
  user     => 'all',
  database => 'all',
  method   => 'md5',
  target   => '/etc/postgresql/9.1/main/pg_hba.conf',
}

pass options for the method

pg_hba { 'Default entry with option':
  method  => 'ident',
  options => { 'sameuser' => undef },
  target  => '/etc/postgresql/9.1/main/pg_hba.conf',
}

pg_hba { 'host to all on all from .dev.example.com in /etc/postgresql/9.1/main/pg_hba.conf':
  method  => 'ldap',
  options => {
    'ldapserver' => 'auth.example.com',
    'ldaptls'    => '1',
    'ldapprefix' => 'uid=',
    'ldapsuffix' => ',ou=people,dc=example,dc=com',
  },
}

insert entry in specific position

pg_hba { 'local to all on all':
  ensure   => present,
  method   => 'md5',
  position => 'before first entry',
  target   => '/etc/postgresql/9.1/main/pg_hba.conf',
}

pg_hba { 'local to all on all':
  ensure   => present,
  method   => 'md5',
  position => 'after last entry',
  target   => '/etc/postgresql/9.1/main/pg_hba.conf',
}

pg_hba { 'local to all on all':
  ensure   => present,
  method   => 'md5',
  position => 'before last local',
  target   => '/etc/postgresql/9.1/main/pg_hba.conf',
}

pg_hba { 'local to all on all':
  ensure   => present,
  method   => 'md5',
  position => 'after first hostssl',
  target   => '/etc/postgresql/9.1/main/pg_hba.conf',
}

pg_hba { 'local to all on all':
  ensure   => present,
  method   => 'md5',
  position => 'after first anyhost', # any type matching host.*
  target   => '/etc/postgresql/9.1/main/pg_hba.conf',
}

pg_hba { 'local to all on all':
  ensure   => present,
  method   => 'md5',
  position => 'before 5', # Before the fifth entry
  target   => '/etc/postgresql/9.1/main/pg_hba.conf',
}

pg_hba { 'local to all on all':
  ensure   => present,
  method   => 'md5',
  position => '*[database="all" and user="admin"][1]', # First entry for database 'all' and user 'admin'
  target   => '/etc/postgresql/9.1/main/pg_hba.conf',
}

ensure position is correct

pg_hba { 'local to all on all':
  ensure   => positioned,
  method   => 'md5',
  position => 'before first entry',
  target   => '/etc/postgresql/9.1/main/pg_hba.conf',
}

delete entry

pg_hba { 'local to all on all':
  ensure => absent,
  target => '/etc/postgresql/9.1/main/pg_hba.conf',
}

pg_hba { 'host to all on all from 192.168.0.1':
  ensure    => absent,
  target => '/etc/postgresql/9.1/main/pg_hba.conf',
}
