pyjamaas

Python Juju and MaaS toolkit.

Features

pyjamaas simplifies interaction with MaaS and Juju when working with a large number of heterogenous machines. It heavily utilizes the MaaS tags mechanism.

Features:

• pyjamaas tags: Easily create, delete and update multiple tags for multiple machines
• pyjamaas clone: Easily clone configuration to multiple machines, using tags
• pyjamaas machine: Utility commands for retrieving machine information

Installation

$ pip install pyjamaas

Configuration

pyjamaas needs MaaS credentials. You can use environment variables:

$ export MAAS_API_URL=https://maas.server.name:5240/MAAS/api/2.0
$ export MAAS_API_KEY=AAAAAAAAAAAAAA:BBBBBBBBBBBBBBB:CCCCCCCCCCCCCCC

Or create a pyjamaas.conf file (see sample):

[maas]
api_url = https://maas.server.name:5240/MAAS/api/2.0
api_key = AAAAAAAAAAAAAA:BBBBBBBBBBBBBBB:CCCCCCCCCCCCCCC

$ pyjamaas <command> --config-file pyjamaas.conf

pyjamaas will automatically look for config files in a few standard directories, e.g. /etc/pyjamaas.conf, /etc/pyjamaas/pyjamaas.conf, ~/.pyjamaas/pyjamaas.conf).

Print loaded configuration with pyjamaas config. If a required option is missing, an error message is printed:

$ pyjamaas config
value required for option api_key in group [maas]

Usage

For a list of available commands:

$ pyjamaas --help

Most pyjamaas commands have the format pyjamaas <command> <args> --match <filter>. The <filter> can be used to select machines based on system_id, hostname, or tags. The examples below should be clear enough:

# Match a single machine using hostname
$ pyjamaas machine list --match '{hostname: host1}'

# Match multiple machines by hostname
$ pyjamaas machine list --match '{hostname: [host1, host2]}'

# Match multiple machines by system id
$ pyjamaas machine list --match '{system_id: [system1, system2]}'

# Match machines using tags (multiple tags imply AND)
$ pyjamaas machine list --match '{tags: [tag1, tag2]}'
