configuretron 0.3.0

Features

• Type-hinted configuration

• Simple, readable YAML configs

• Config in source control

• Secrets safely in source control

• Easily swap environments

• Control who can encrypt and decrypt

Installation

$ python -m pip install configuretron

Usage

config.yml

config:
    api_url: https://apitopia.com/api/v1
    api_timeout: 20

config.py

@dataclass
class Config:
    api_url: str
    api_timeout: int = 30

config = configuretron.from_yaml(Config, "config.yml")

Adding Secrets

Adding encryption just takes a few console commands

$ python -m configuretron --yaml=config.yml setup_encryption

Copy the generated base64 private key into an environment variable (in this example, PRIVATE_KEY)

Encrypt and variables in the config (in this example, api_token):

$ python -m configuretron --yaml=config.yml encrypt --key api_token

Then pass the key to the config

private_key = configuretron.env_base64_value('PRIVATE_KEY')
config = configuretron.from_yaml(Config, "config.yml", private_key=private_key)

Environmental overrides

To override values per-environment, add them into the config like so:

config:
    api_url: http://localhost:8080/api/v1
    api_timeout: 20
env:
    prod:
        config:
            api_url: https://apitopia.com/api/v1

Then just pass env when initializing the configuration:

config = configuretron.from_yaml(Config, "config.yml", env="prod")

TODO Features

• Config heirarchy
