passport 0.1.1

Description:

passport 0.1.1

Light weight configuration management using Consul
Passport is a command line tool for rendering templates containing information
gained from Consul’s Service Discovery API and Key/Value database.


Installation
Passport is available via pypi and
can be installed with easy_install or pip:
pip install passport


Usage
usage: passport.py [-h] [--host HOST] [--port PORT] [--datacenter DATACENTER]
{kv,file} path destination


Example
As an example, the following template is stored in the KV database as
templates/memcached/memcached.conf
{% set nodes = ['%s:%s' % (r['Address'], r['ServicePort']) for r in consul.catalog.service('memcached')] %}

[memcached]
servers = {{ ','.join(nodes) }}
Invoking passport will render the file with a list of all memcached nodes to
/etc/memcached.conf.
passport kv templates/memcached/memcached.conf /etc/memcached.conf
And the output would look something like:
[memcached]
servers = 172.17.0.7:11211,172.17.0.8:11211
Template rendering is done via the Tornado Template engine.


Todo

Add a managed mode where Passport will check for new services on a regular interval and when changes occur, update the rendered template and notify a process using HUP
Add daemonization for managed mode
Add the ability to specify pairs of templates/destinations in a single invocation
