puppet_wal_e

Description

Postgresql wal_e puppet module, install wal-e backup program from source or through pip. Some parts are based on chef module from wal-e project.

It supports cron job setup for base backup.

Most functionality has been tested on Centos 7 and Ubuntu 14.04.

Requirement

env_dir of Daemontools package is required to ease setup of environment variables for different storage backends. Module user need to install it as dependency.

Python and pip dependencies will be installed, documented at wal_e github page.

Depends on the cloud storage backend, configuration is required.

Usage

class {'wal_e':
 env_dir => '/etc/wal-e.d' #default to this folder
 user => 'postgres',
 group => 'postgres',
 storage_type => 'aws' #default to aws
 storage_configs => {
   's3_prefix' => 's3://dummy',
   'aws_secret_key' => '',
   'aws_access_key' => '',
   'aws_region' => 'us-east-1',
 }
}
