Atlasbroker module

Installation

This package is available for Python 3.5+.

pip3 install atlasbroker

Or install the development version from github:

pip3 install git+https://github.com/mickybart/python-atlasbroker.git

Prerequisite

Examples in this README are using the secret.json file to inject Atlas and Mongo credentials. Of course you can use any other solution provided by your infrastructure.

# Secrets structure
#
secrets = {
    "mongo" : {
        "uri": "",
        "db": "",
        "timeoutms": 5000,
        "collection" : ""
    },
    "atlas" : {
        "user": "",
        "password" : "",
        "group" : ""
    }
}

Quick start

from atlasbroker.broker import Broker
from atlasbroker.config import Config

secrets = Config.load_json("secret.json")

config = Config(secrets["atlas"], secrets["mongo"])

Broker(config).run()

Custom Config

The class Config is the main way to customize the broker. All important functions like generate credentials, database name, permissions of the database user, UUID, etc are exposed on this class.

Please read the Code documentation for more details.

from atlasbroker.broker import Broker
from atlasbroker.config import Config

secrets = Config.load_json("secret.json")

class CustomConfig(Config):
    PARAMETER_NAMESPACE="ns"

    def generate_binding_username(self, binding):
        return binding.binding_id + '-rw'

    def generate_instance_dbname(self, instance):
        return instance.parameters[self.PARAMETER_NAMESPACE]

config = CustomConfig(secrets["atlas"], secrets["mongo"])

Broker(config).run()
