Joker is a configuration data collector framework for OpenStack-based clouds. This framework inspects hardware and software configuration of cloud components. The results of this inspection are used to create Architecture Data Model which could be exported and used by external services.

Installation and configuration

Usage and integration

Architecture data model produced by Joker could be consumed by configuration validator tool (Dark Knight), by architecture graph (Stencil) and others.

At some point it should be made convertible into format accepted by deployment systems (e.g. Fuel or TripleO) which will allow to effectively 'clone' OpenStack clouds using different deployment applications.

This model could be reused by Rally project to compare benchmarking results for different architectures.

The model can be used to inspect existing clouds for subsequent upgrade.

The model suits as base for questionaire to assess existing installations for support contract pricing purposes.

Architecture Data Model

This section proposes data model which allows to describe any OpenStack installation. The model includes data regarding physical infrastructure, logical topology of services and mapping between the two.

Architecture data model could be serialized as JSON or YaML document of the following format::

openstack
    nodes
        node1
            -param1: value
            -param2: value
    services
        nova
            configuration
                -param1: value
                -param2: value
