Roboconf

Quick Introduction

Roboconf In Few Words

  • A deployment solution (cloud, but not only)
  • Describe Software elements and their relations
  • Parallel deployments
  • Asynchroneous configuration through AMQP

Simple example: LAMP use case

lamp

Initial deployment (+ add a 2nd Tomcat).

Automatic reconfiguration.

How it works: step 1

step

Initial setup: VM « 0 » + Appliance for the agent.

How it works: step 2

Deployment Graph (LAMP)

Tomcat contains all the WAR to run. Fine for legacy.

Model Principles

  1. Configuration Files
    • Describe Software components and their relations (graph)
    • Define initial instances / deployment

  2. API
    • Load, validate and manipulate a model (graph or instances)
    • To be used in platform and tools

The (oriented) Graph

The graph defines relations between Software components.
Two kinds of relations are considered.


Containment

A component has to be deployed onto another one.
Example: a war onto a web application server.


Runtime

A component needs another one to run.
A component provides a feature another component may need. Example: a war depends on a MySQL database.

Roboconf's Model

Roboconf's model is made up of 3 elements:

  • The graph definition.
  • Resources that will be used by Roboconf to perform the creation of instances. This goes with the graph.
  • The definition of an application (instance).


Graph node => Associated plugin.

Instances

graph
  • Instances 1: a VM with Apache and MySQL
  • Instances 2: a VM with Apache Tomcat and the WAR

Tools for Roboconf

tools

The model is a central project for all these tools.
Monitoring features and the semi-autonomous administration agent will come later.

Ongoing Work


Runtime

  • New configuration files <=> New Model
  • Upgrade the REST API
  • 2 Web Applications
  • Create a Maven plug-in (validation, packaging)


Demo & Publication

  • http://roboconf.net
  • Migrate existing examples
  • Code Quality & Code moved to GitHub
