CMT -- Cluster Management Tool

CMT is a Cluster Management Tool originally created at SARA Computing and Networking Services, which is based in Amsterdam and known as SARA nowadays. It once started as a single script, went through some reincarnations, and now it consists of a Django-powered backend on the server-side, and a CLI for the client-side.

The main reason behind CMT's existence is that we needed a tool that's capable of generating configuration-files for certain software running on our clusters. CMT has a database, where we store information about our hardware, which is used to (let CMT) generate configuration-files, based on templates. At SARA it's used in production, to generate configuration-files for services like for example dhcpd and bind. At the moment we're busy to make Python packages, to make it easy to install.

Features

Some features of CMT are:

• Dynamically extendable data model
• Server-side Django-powered easy-to-use web-interface
• Client-side powerful CLI, to use CMT from shellscripts, or interactive from shell
• Automagic generation of configuration files, with templates extended on Django Templates
• Export stored data to, and import from JSON
• Support for multiple clusters, networks, interfaces, etc...
• Easy to install package for the client-side functionalities

Wished features for future releases are:

• Import the client as a Python-module
• Split server- and client-functionalities as much as possible, and develop as packages apart from each other
• Build an API to make it easier to integrate CMT in other software/scripts
