While on top-level configuration management tools usually have key/value interfaces, in the layer below other techniques are used, such as:
In this talk, we will discuss a new approach using a key/value interface in every layer of configuration access, implemented in Puppet-Libelektra. Different to other key/value APIs Puppet-Libelektra is independent of the concrete configuration file format, abstracts from the syntax, and supports validation.
In a time-consuming user study we found the key/value interface to be significantly faster to use. Because of integrated validation it is also more safe, and because of local tooling it is easier to use. Puppet-Libelektra is already used in practice: Elektra's web and build server is managed using Puppet-Libelektra.
