hostlist 1.1.0rc2

Sync hostlist and builds config files for services.

Hostlist reads yaml lists with information about hosts and generates config files and inventory for several services.

Quickstart

Example input files are in the tests directory. Hostlists are defined in the hostslists subdirectory, where the filename encodes the hosttype and institute attributes of the contained hosts.

Run buildfiles to generate the output. buildfiles –help shows the available options.

Configuration

The main configuration is in config.yml in the working directory. Hostlists are collected in a directory listed in config.yml.

Services

At the moment the supported services are:

• /etc/hosts, can also be used for dnsmasq

• dhcpd

• ansible inventory

• munin

• ssh_known_hosts generation

Web daemon

You can start hostlist-daemon to serve the generated content via http. Start hostlist-daemon where you would run buildfiles. The daemon is based on cherrypy and has a config file daemon.conf.

Example

A working example for inputs and all configuratino files can be found in tests.

DNSVS Synchronization

Besides generating config files, the hostlist can also be synchronized against DNSVS, which is the dns management system used by https://www.scc.kit.edu.

Tests

To run the tests:

cd tests; py.test
