Description

This Puppet module provides the dotenv defined type for managing .env files commonly used for storing configuration separately from application code; see the The Twelve-Factor App methodology for details of this concept.

The module also supplies the dotenv function that produces a string representation of .env file contents from a Puppet hash.

Setup Requirements

This module depends on the puppetlabs/stdlib module.

Usage

dotenv defined type

The dotenv defined type has the following attributes:

  • path (namevar) – absolute path to the .env file to manage;
  • ensure (default: present) – manages the file as present or absent;
  • mode (default: undef) – file mode to set (DAC permissions);
  • owner (default: undef) – file owner to set;
  • group (default: undef) – file group to set;
  • force (default: false) – see the force attribute of the underlying file resource type;
  • entries – hash of key-value entries to write into the file.

dotenv function

The dotenv function takes a Puppet hash of key-value entries as its sole parameter and returns a string that represents the corresponding .env file contents.

Please see the last example below for a use case.

Examples

Manage a web application configuration file:

dotenv { 'Web app config':
  path    => '/var/www/app/.env',
  mode    => '0400',
  owner   => 'www-data',
  group   => 'www-data',
  entries => {
    'MYSQL_HOSTNAME' => 'localhost',
    'MYSQL_USERNAME' => 'user',
    'MYSQL_PASSWORD' => 'secret',
    'MYSQL_DATABASE' => 'dbname',
  },
}

The result in the /var/www/app/.env file will be:

# Managed by Puppet

MYSQL_HOSTNAME="localhost"
MYSQL_USERNAME="user"
MYSQL_PASSWORD="secret"
MYSQL_DATABASE="dbname"

Manage a web application configuration file with entries looked up in Hiera:

$entries = lookup('app_env', Hash, deep)

dotenv { 'Web app config':
  path    => '/var/www/app/.env',
  mode    => '0400',
  owner   => 'www-data',
  group   => 'www-data',
  entries => $entries,
}

Previous example using the base file resource type and the dotenv function (in case you might want more control over the resource attributes–note the backup attribute):

$entries = lookup('app_env', Hash, deep)

file { 'Web app config':
  path    => '/var/www/app/.env',
  backup  => false,
  mode    => '0400',
  owner   => 'www-data',
  group   => 'www-data',
  content => dotenv($entries),
}

Limitations

The dotenv defined type is a wrapper around the file resource type and implements a narrow subset of its attributes.

Credits

The dotenv function is a stripped down version of the hash2kv function from the mmckinst/hash2stuff module by Mark McKinstry.
