theblues 0.0.4

Python library for using the juju charm store API.

Python library for using the juju charmstore API.

Installation

The easiest way to install theblues is via pip:

$ pip install theblues

Note that theblues requires python-macaroons (which has its own dependencies), which must be installed from a ppa:

$ sudo add-apt-repository ppa:yellow/ppa -y
$ apt-get install libmacaroons0 python-macaroons libsodium13

Without these, theblues cannot communicate with the charmstore.

Usage

Interacting with the charmstore is pretty simple. To look up an entity on the charmstore (e.g. a charm or bundle):

>>> from theblues.charmstore import CharmStore
>>> cs = CharmStore('https://api.jujucharms.com/v4')
>>> entity = cs.entity('wordpress')
>>> entity['Id']
u'cs:trusty/wordpress-2'

Data for an entity is contained in the Meta item of the response, matching the json returned from the charmstores:

>>> entity['Meta']['charm-metadata']['Name']
u'wordpress'

You can also get files for the entity:

>>> cs.files('wordpress')['hooks/install']
u'https://api.jujucharms.com/v4/wordpress/archive/hooks/install
>>> hook = cs.files('wordpress', filename='hooks/install', read_file=True)
>>> print hook
#!/bin/bash

set -xe
