Description

This module provides a Hiera 5 backend for Redis.

Setup

Setup Requirements

The backend requires the redis gem installed in the Puppet Server JRuby. It can be installed with:

/opt/puppetlabs/bin/puppetserver gem install redis

It is also recommended to install the gem into the agent's Ruby:

/opt/puppetlabs/puppet/bin/gem install redis

This allows commands such as puppet apply or puppet lookup to use the backend.

Beginning with hiera_redis

If Redis is running on the Puppet master with the default settings, specifying the lookup_key as 'redis_lookup_key' is sufficient, for example:

---
version: 5
hierarchy:
  - name: hiera_redis
    lookup_key: redis_lookup_key

Usage

By default, the backend will query Redis with the key provided. It is also possible to query multiple scopes such as with the YAML backend, where the expected key in Redis is composed of the scope and the key separated by a character (default is :). For example, the following can be used:

---
version: 5
hierarchy:
  - name: hiera_redis
    lookup_key: redis_lookup_key
    options:
      scopes:
        - osfamily/%{facts.os.family}
        - common

The backend then expects keys of a format such as common:foo::bar for a lookup of 'foo::bar'.

The other options available include:

  • host: The host that Redis is located on. Defaults to 'localhost'.
  • port: The port that Redis is running on. Defaults to 6379.
  • db: The database number to query on the Redis instance. Defaults to 0.
  • scope: The scope to use when querying the database.
  • scopes: An array of scopes to query. Cannot be used in conjunction with the scope option.
  • separator: The character separator between the scope and key being queried. Defaults to ':'.

Limitations

This module has only been tested on CentOS.
