Module description

The postgresql module allows you to manage PostgreSQL databases with Puppet.

PostgreSQL is a high-performance, free, open-source relational database server. The postgresql module allows you to manage packages, services, databases, users, and common security settings in PostgreSQL.

Setup

What postgresql affects

  • Package, service, and configuration files for PostgreSQL
  • Listened-to ports
  • IP and mask (optional)

Getting started with postgresql

To configure a basic default PostgreSQL server, declare the postgresql::server class.

class { 'postgresql::server': }

Usage

Configure a server

For default settings, declare the postgresql::server class as above. To customize PostgreSQL server settings, specify the parameters you want to change:

class { 'postgresql::server':
  ip_mask_deny_postgres_user => '0.0.0.0/32',
  ip_mask_allow_all_users    => '0.0.0.0/0',
  listen_addresses           => '*',
  ipv4acls                   => ['hostssl all johndoe 192.168.0.0/24 cert'],
  postgres_password          => 'TPSrep0rt!',
}

After configuration, test your settings from the command line:

psql -h localhost -U postgres
psql -h my.postgres.server -U

If you get an error message from these commands, your permission settings restrict access from the location you're trying to connect from. Depending on whether you want to allow connections from that location, you might need to adjust your permissions.

For more details about server configuration parameters, consult the PostgreSQL Runtime Configuration documentation.

Create a database

You can set up a variety of PostgreSQL databases with the postgresql::server::db defined type. For instance, to set up a database for PuppetDB:

class { 'postgresql::server': }

postgresql::server::db { 'mydatabasename':
  user     => 'mydatabaseuser',
  password => postgresql_password('mydatabaseuser', 'mypassword'),
}

Manage users, roles, and permissions

To manage users, roles, and permissions:

class { 'postgresql::server': }

postgresql::server::role { 'marmot':
password_hash => postgresql_password('marmot', 'mypasswd'),
}

postgresql::server::database_grant { 'test1':
  privilege => 'ALL',
  db        => 'test1',
  role      => 'marmot',
}

postgresql::server::table_grant { 'my_table of test2':
  privilege => 'ALL',
  table     => 'my_table',
  db        => 'test2',
  role      => 'marmot',
}

This example grants all privileges on the test1 database and on the my_table table of the test2 database to the specified user or group. After the values are added into the PuppetDB config file, this database would be ready for use.

Override defaults

The postgresql::globals class allows you to configure the main settings for this module globally, so that other classes and defined resources can use them. By itself, it does nothing.

For example, to overwrite the default locale and encoding for all classes, use the following:

class { 'postgresql::globals':
  encoding => 'UTF-8',
  locale   => 'en_US.UTF-8',
}->
class { 'postgresql::server':
}

To use a specific version of the PostgreSQL package:

class { 'postgresql::globals':
  manage_package_repo => true,
  version             => '9.2',
}->
class { 'postgresql::server': }

Manage remote users, roles, and permissions

Remote SQL objects are managed using the same Puppet resources as local SQL objects, along with a connect_settings hash. This provides control over how Puppet connects to the remote Postgres instances and which version is used for generating SQL commands.

The connect_settings hash can contain environment variables to control Postgres client connections, such as 'PGHOST', 'PGPORT', 'PGPASSWORD', and 'PGSSLKEY'. See the PostgreSQL Environment Variables documentation for a complete list of variables.

Additionally, you can specify the target database version with the special value of 'DBVERSION'. If the connect_settings hash is omitted or empty, then Puppet connects to the local PostgreSQL instance.

You can provide a connect_settings hash for each of the Puppet resources, or you can set a default connect_settings hash in postgresql::globals. Configuring connect_settings per resource allows SQL objects to be created on multiple databases by multiple users.

$connection_settings_super2 = {
                                 'PGUSER'     => "super2",
                                 'PGPASSWORD' => "foobar2",
                                 'PGHOST'     => "127.0.0.1",
                                 'PGPORT'     => "5432",
                                 'PGDATABASE' => "postgres",
                                }

include postgresql::server

# Connect with no special settings, i.e domain sockets, user postgres
postgresql::server::role{'super2':
  password_hash => "foobar2",
  superuser     => true,

  connect_settings => {},
  require          => [
                       Class['postgresql::globals'],
                       Class['postgresql::server::service'],
                      ],
}

# Now using this new user connect via TCP
postgresql::server::database { 'db1':
  connect_settings => $connection_settings_super2,

require => Postgresql::Server::Role['super2'],
}

Create an access rule for pg_hba.conf

To create an access rule for pg_hba.conf:

postgresql::server::pg_hba_rule { 'allow application network to access app database':
  description => "Open up PostgreSQL for access from 200.1.2.0/24",
  type        => 'host',
  database    => 'app',
  user        => 'app',
  address     => '200.1.2.0/24',
  auth_method => 'md5',
}

This would create a ruleset in pg_hba.conf similar to:

# Rule Name: allow application network to access app database
# Description: Open up PostgreSQL for access from 200.1.2.0/24
# Order: 150
host  app  app  200.1.2.0/24  md5

By default, pg_hba_rule requires that you include postgresql::server. However, you can override that behavior by setting target and postgresql_version when declaring your rule. That might look like the following:

postgresql::server::pg_hba_rule { 'allow application network to access app database':
  description        => "Open up postgresql for access from 200.1.2.0/24",
  type               => 'host',
  database           => 'app',
  user               => 'app',
  address            => '200.1.2.0/24',
  auth_method        => 'md5',
  target             => '/path/to/pg_hba.conf',
  postgresql_version => '9.4',
}

Create user name maps for pg_ident.conf

To create a user name map for the pg_ident.conf:

postgresql::server::pg_ident_rule{ 'Map the SSL certificate of the backup server as a replication user':
  map_name          => 'sslrepli',
  system_username   => 'repli1.example.com',
  database_username => 'replication',
}

This would create a user name map in pg_ident.conf similar to:

#Rule Name: Map the SSL certificate of the backup server as a replication user
#Description: none
#Order: 150
sslrepli  repli1.example.com  replication

Create recovery configuration

To create the recovery configuration file (recovery.conf):

postgresql::server::recovery{ 'Create a recovery.conf file with the following defined parameters':
  restore_command                => 'cp /mnt/server/archivedir/%f %p',
  archive_cleanup_command        => undef,
  recovery_end_command           => undef,
  recovery_target_name           => 'daily backup 2015-01-26',
  recovery_target_time           => '2015-02-08 22:39:00 EST',
  recovery_target_xid            => undef,
  recovery_target_inclusive      => true,
  recovery_target                => 'immediate',
  recovery_target_timeline       => 'latest',
  pause_at_recovery_target       => true,
  standby_mode                   => 'on',
  primary_conninfo               => 'host=localhost port=5432',
  primary_slot_name              => undef,
  trigger_file                   => undef,
 recovery_min_apply_delay        => 0,
}

The above creates this recovery.conf config file:

restore_command = 'cp /mnt/server/archivedir/%f %p'
recovery_target_name = 'daily backup 2015-01-26'
recovery_target_time = '2015-02-08 22:39:00 EST'
recovery_target_inclusive = true
recovery_target = 'immediate'
recovery_target_timeline = 'latest'
pause_at_recovery_target = true
standby_mode = 'on'
primary_conninfo = 'host=localhost port=5432'
recovery_min_apply_delay = 0

Only the specified parameters are recognized in the template. The recovery.conf is only be created if at least one parameter is set and manage_recovery_conf is set to true.

Validate connectivity

To validate client connections to a remote PostgreSQL database before starting dependent tasks, use the postgresql::validate_db_connection resource. You can use this on any node where the PostgreSQL client software is installed. It is often chained to other tasks such as starting an application server or performing a database migration.

Example usage:

postgresql::validate_db_connection { 'validate my postgres connection':
  database_host           => 'my.postgres.host',
  database_username       => 'mydbuser',
  database_password       => 'mydbpassword',
  database_name           => 'mydbname',
}->
exec { 'rake db:migrate':
  cwd => '/opt/myrubyapp',
}

Classes

postgresql::client

Installs PostgreSQL client software. Set the following parameters if you have a custom version you would like to install.

Note: Make sure to add any necessary yum or apt repositories if specifying a custom version.

package_ensure

Whether the PostgreSQL client package resource should be present. Valid values: 'present', 'absent'. Default: 'present'.

package_name

Sets the name of the PostgreSQL client package. Default: 'file'.

validcon_script_path

Specifies the path to validate the connection script. Default: '/usr/local/bin/validate_postgresql_connection.sh'.

postgresql::lib::docs

Installs PostgreSQL bindings for Postgres-Docs. Set the following parameters if you have a custom version you would like to install.

Note: Make sure to add any necessary yum or apt repositories if specifying a custom version.

package_name

Specifies the name of the PostgreSQL docs package.

package_ensure

Whether the PostgreSQL docs package resource should be present. Valid values: 'present', 'absent'. Default: 'present'.

postgresql::globals

Note: Most server-specific defaults should be overridden in the postgresql::server class. This class should be used only if you are using a non-standard OS, or if you are changing elements that can only be changed here, such as version or manage_package_repo.

bindir

Overrides the default PostgreSQL binaries directory for the target platform. Default: OS dependent.

client_package_name

Overrides the default PostgreSQL client package name. Default: OS dependent.

confdir

Overrides the default PostgreSQL configuration directory for the target platform. Default: OS dependent.

contrib_package_name

Overrides the default PostgreSQL contrib package name. Default: OS dependent.

createdb_path

Deprecated. Path to the createdb command. Default: "${bindir}/createdb".

datadir

Overrides the default PostgreSQL data directory for the target platform. Default: OS dependent.

Note: Changing the datadir after installation causes the server to come to a full stop before making the change. For Red Hat systems, the data directory must be labeled appropriately for SELinux. On Ubuntu, you must explicitly set needs_initdb = true to allow Puppet to initialize the database in the new datadir (needs_initdb defaults to true on other systems).

Warning: If datadir is changed from the default, Puppet does not manage purging of the original data directory, which causes it to fail if the data directory is changed back to the original.

default_database

Specifies the name of the default database to connect with. On most systems, this is 'postgres'.

devel_package_name

Overrides the default PostgreSQL devel package name. Default: OS dependent.

docs_package_name

Overrides the default PostgreSQL docs package name. If not specified, the module uses the default for your OS distro.

encoding

Sets the default encoding for all databases created with this module. On certain operating systems, this is also used during the template1 initialization, so it becomes a default outside of the module as well. Defaults to the operating system's default encoding.

Overrides the default postgres user group to be used for related files in the file system. Default: 'postgres'.

initdb_path

Path to the initdb command.

java_package_name

Overrides the default PostgreSQL java package name. Default: OS dependent.

locale

Sets the default database locale for all databases created with this module. On certain operating systems, this is also used during the template1 initialization, so it becomes a default outside of the module as well. Default: undef, which is effectively C. On Debian, you'll need to ensure that the 'locales-all' package is installed for full functionality of PostgreSQL.

logdir

Overrides the default PostgreSQL log directory. Default: initdb's default path.

manage_package_repo

Sets up official PostgreSQL repositories on your host if set to true. Default: false.

needs_initdb

Explicitly calls the initdb operation after the server package is installed and before the PostgreSQL service is started. Default: OS dependent.

perl_package_name

Overrides the default PostgreSQL Perl package name. Default: OS dependent.

pg_hba_conf_defaults

Disables the defaults supplied with the module for pg_hba.conf if set to false. This is useful if you want to override the defaults. Be sure that your changes align with the rest of the module, as some access is required to perform some operations, such as basic psql operations. Default: true.

pg_hba_conf_path

Specifies the path to your pg_hba.conf file. Default: '${confdir}/pg_hba.conf'.

pg_ident_conf_path

service_name

Overrides the default PostgreSQL service name. Default: OS dependent.

service_provider

Overrides the default PostgreSQL service provider. Default: OS dependent.

  • 'localhost': Accept connections from local host only.
  • '*': Accept connections from any remote machine.
  • Specified comma-separated list of hostnames or IP addresses.
locale

Sets the default database locale for all databases created with this module. On certain operating systems this is used during the template1 initialization as well, so it becomes a default outside of the module. Default: undef, which is effectively C. On Debian, you must ensure that the 'locales-all' package is installed for full functionality of PostgreSQL.

manage_pg_hba_conf

Whether to manage the pg_hba.conf. If set to true, Puppet overwrites this file. If set to false, Puppet does not modify the file. Valid values: true, false. Default

Passes a value through to the package resource when creating the server instance. Default: undef.

package_name

Specifies the name of the package to use for installing the server software. Default: OS dependent.

pg_hba_conf_defaults

If false, disables the defaults supplied with the module for pg_hba.conf. This is useful if you disagree with the defaults and wish to override them yourself. Be sure that your changes of course align with the rest of the module, as some access is required to perform basic psql operations for example.

port

Specifies the port for the PostgreSQL server to listen on. Note: The same port number is used for all IP addresses the server listens on. Also, for Red Hat systems and early Debian systems, changing the port causes the server to come to a full stop before being able to make the change. Default: 5432, meaning the Postgres server listens on TCP port 5432.

postgres_password

Sets the password for the postgres user to your specified value. Default: undef, meaning the superuser account in the Postgres database is a user called postgres and this account does not have a password.

  • primary_conninfo
  • primary_slot_name
  • trigger_file
  • recovery_min_apply_delay
target

Provides the target for the rule, and is generally an internal only property. Use with caution.

postgresql::server::role

Creates a role or user in PostgreSQL.

connection_limit

Specifies how many concurrent connections the role can make. Default: -1, meaning no limit.

Specifies whether to grant login capability for the new role. Default: true.

password_hash

Sets the hash to use during password creation. If the password is not already pre-encrypted in a format that PostgreSQL supports, use the postgresql_password function to provide an MD5 hash here, for example:

postgresql::server::role { "myusername":
password_hash => postgresql_password('myusername', 'mypassword'),
}
replication

Provides provides replication capabilities for this role if set to true. Default: false.

postgresql::validate_db_connection

Validates client connection with a remote PostgreSQL database.

connect_settings

Specifies a hash of environment variables used when connecting to a remote server. This is an alternative to providing individual parameters (database_host, etc.). If provided, the individual parameters take precedence.

create_db_first

sleep

Sets the number of seconds to sleep for before trying again after a failure.

tries

Sets the number of attempts after failure before giving up and failing the resource.

Types

name

Specifies the name of the slot to create. Must be a valid replication slot name. This is the namevar.

Functions

postgresql_password

Generates a PostgreSQL encrypted password, use postgresql_password. Call it from the command line and then copy and paste the encrypted password into your manifest:

puppet apply --execute 'notify { "test": message => postgresql_password("username", "password") }'

Alternatively, you can call this from your production manifests, but the manifests will then contain a clear text version of your passwords.

postgresql_acls_to_resources_hash(acl_array, id, order_offset)

This internal function converts a list of pg_hba.conf based ACLs (passed in as an array of strings) to a format compatible with the postgresql::pg_hba_rule resource.

This function should only be used internally by the module.

Limitations

Works with versions of PostgreSQL from 8.1 through 9.5.

Currently, the postgresql module is tested on the following operating systems:

  • Debian 6.x, 7.x, 8.x.
  • CentOS 5.x, 6.x, and 7.x.
  • Ubuntu 10.04 and 12.04, 14.04.

Other systems might be compatible, but are not being actively tested.

Apt module support

While this module supports both 1.x and 2.x versions of the puppetlabs-apt module, it does not support puppetlabs-apt 2.0.0 or 2.0.1.

PostGIS support

PostGIS is currently considered an unsupported feature, as it doesn't work on all platforms correctly.

All versions of RHEL/CentOS

If you have SELinux enabled you must add any custom ports you use to the postgresql_port_t context. You can do this as follows:

semanage port -a -t postgresql_port_t -p tcp $customport

Development

Puppet Labs modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can’t access the huge number of platforms and myriad hardware, software, and deployment configurations that Puppet is intended to serve. We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things. For more information, see our module contribution guide.

Tests

There are two types of tests distributed with this module. Unit tests with rspec-puppet and system tests using rspec-system.

For unit testing, make sure you have:

  • rake
  • bundler

Install the necessary gems:

bundle install --path=vendor

And then run the unit tests:

bundle exec rake spec

The unit tests are run in Travis-CI as well. If you want to see the results of your own tests, register the service hook through Travis-CI via the accounts section for your GitHub clone of this project.

To run the system tests, make sure you also have:

  • Vagrant > 1.2.x
  • VirtualBox > 4.2.10

Then run the tests using:

bundle exec rspec spec/acceptance

To run the tests on different operating systems, see the sets available in .nodeset.yml and run the specific set with the following syntax:

RSPEC_SET=debian-607-x64 bundle exec rspec spec/acceptance
