Chef cookbook Code Climate Build Status

Description

This cookbook includes recipes and providers to install and configure postgresql database. This cookbook was tested with Postgresql 9.1, 9.2, 9.3, 9.4, 9.5, 9.6 & 10.

Supported platforms:

  • Debian 8
  • Debian 9
  • Ubuntu 14.04
  • Ubuntu 16.04
  • Ubuntu 18.04

Note: TravisCI tests for Ubuntu 18.04 are omitted now because they somehow hang. Local Vagrant & Docker-based tests are succesfull. This will be investigated further.

Changelog

See CHANGELOG.md

Requirements

The minimal recommended version of chef-client is 13.0.113. It may still work on version 12.5.1 and older, but no tests are made starting from version 1.3.0 of this cookbook as Chef 12 is reaching its EOL in the April, 2018

Dependencies

  • apt
  • cron
  • poise-python

Attributes

This cookbook have server and client attribute files.

With client attributes(["postgresql"]["client"]) you can set only postgresql client and library version.

Server attributes are starting from ["postgresql"]["defaults"] and used as default attributes for postgresql provider. You should not override this defaults, you can pass your settings to provider instead.

Resources/Providers

Resource: default

Actions

  • :create: creates postgresql cluster

Resource parameters

  • cluster_name: name attribute. Cluster name (e.g. main). Be aware, systemd (in Ubuntu 16.04 and Debian Jessie) not working with cluster names that containing dashes ('-').
  • cluster_version: set cluster version
  • cookbook: cookbook for templates. Skip this for default templates.
  • cluster_create_options: options for pg_createcluster (only locale related options)
  • configuration: Hash with configuration options for postgresql, see examples.
  • hba_configuration: Array with hba configuration, see examples.
  • ident_configuration: Array with ident configuration, see examples.
  • replication: Hash with replication configuration. See replication example.
  • replication_initial_copy: Boolean. If true pg_basebackup will be exec to make initial replication copy. Default is false.
  • replication_start_slave: Boolean. If true slave cluster will be started after creation. Should be used with replication_initial_copy option. Default false.
  • allow_restart_cluster: Can be first, always or none. Specifies when cluster must restart instead of reload. first – only first time after installation. always – always restart, even if changes doesn't require restart. none - never, use reload every time. Default is none.

Other

Cloud backup helper:

postgresql_cloud_backup_helper.sh helper can be found at /opt/wal-e/bin/.

Usage:

postgresql_cloud_backup_helper.sh <cluster_name> <cluster_version> last|count

  • cluster_name – postgresql cluster name (ex. main)
  • cluser_version – postgresql cluser version (ex. 9.3)
  • last – shows last backup time
  • count – shows total number of backups.

Examples

Example master database setup:

postgresql 'main' do
  cluster_version '9.3'
  cluster_create_options( locale: 'ru_RU.UTF-8' )
  configuration(
      listen_addresses:           '192.168.0.2',
      max_connections:            300,
      ssl_renegotiation_limit:    0,
      shared_buffers:             '512MB',
      maintenance_work_mem:       '64MB',
      work_mem:                   '8MB',
      log_min_duration_statement: 200
  )
  hba_configuration(
    [
      { type: 'host', database: 'all', user: 'all', address: '192.168.0.0/24', method: 'md5' },
      { type: 'host', database: 'replication', user: 'postgres', address: '192.168.0.3/32', method: 'trust' }
    ]
  )
end

Example slave database setup:

postgresql 'main' do
   cluster_version '9.3'
  cluster_create_options( locale: 'ru_RU.UTF-8' )
  configuration(
      listen_addresses:           '192.168.0.3',
      max_connections:            300,
      ssl_renegotiation_limit:    0,
      shared_buffers:             '512MB',
      maintenance_work_mem:       '64MB',
      work_mem:                   '8MB',
      log_min_duration_statement: 200
  )
  hba_configuration(
    [
      { type: 'host', database: 'all', user: 'all', address: '192.168.0.0/24', method: 'md5' },
      { type: 'host', database: 'replication', user: 'postgres', address: '192.168.0.2/32', method: 'trust' }
    ]
  )
  replication(
    standby_mode: 'on',
    primary_conninfo: 'host=192.168.0.1',
    trigger_file: '/tmp/pgtrigger'
  )
  replication_initial_copy true
  replication_start_slave true
end

Example slave configuration with replication slots (PostgreSQL >= 9.4)

replication(
  standby_mode: 'on',
  primary_conninfo: 'host=192.168.0.1',
  trigger_file: '/tmp/pgtrigger'
  primary_slot_name: 'some_slot_on_master'
)

Don't forget to create slot on master server before:

# SELECT pg_create_physical_replication_slot('some_slot_on_master');

Example users and databases setup

postgresql_user 'user01' do
  in_version '9.3'
  in_cluster 'main'
  unencrypted_password 'user01password'
end

postgresql_database 'database01' do
  in_version '9.3'
  in_cluster 'main'
  owner 'user01'
end

Example full daily database backup

postgresql_cloud_backup 'main' do
  in_version '9.3'
  in_cluster 'main'
  full_backup_time weekday: '*', month: '*', day: '*', hour: '3', minute: '0'
  # Data bag item should contain following keys for S3 protocol:
  # aws_access_key_id, aws_secret_access_key, wale_s3_prefix
  parameters Chef::EncryptedDataBagItem.load('s3', 'secrets').to_hash.select {|i| i != "id"}
  # Or just a hash, if you don't use data bags:
  parameters { aws_access_key_id: 'access_key', aws_secret_access_key: 'secret_key', wale_s3_prefix: 's3_prefix' }
  protocol 's3'
  # In case you need to prepend wal-e with, for example, traffic limiter
  # you can use following method:
  command_prefix 'trickle -s -u 1024'
  # It will be prepended to resulting wal-e execution in cron task
end

Example usage of cloud backup helper usage

$ /opt/wal-e/bin/postgresql_cloud_backup_helper.sh main 9.3 last
1428192159
$ /opt/wal-e/bin/postgresql_cloud_backup_helper.sh main 9.3 count
31

Example of how to install extensions from postgresql-contrib NOTE: schema and version are optional parameters, but others are required

postgresql_extension 'cube' do
  in_version '9.4'
  in_cluster 'main'
  db 'test01'
  schema 'public'
end

Example of how to install extensions from http://pgxn.org/ NOTE: schema is an optional parameter, but others are required

pgxn_extension 'pg_lambda' do
  in_version '9.4'
  in_cluster 'main'
  db 'test01'
  version '1.0.2'
  stage 'stable'
end
