Load YAML configs with environment variables interpolation
Project description
Piny
YAML configs loader with environment variables interpolation for Python.
Keep your app’s configuration in YAML file with sensitive data marked as environment variables. Put sensitive data into environment variables. Then let piny interpolate the variables on YAML loading.
Piny is a recursive acronym for Piny Is Not YAML
Installation
Install using pip install -U piny.
Usage
Set your environment variables, add them to your YAML configuration file:
db:
login: user
password: ${DB_PASSWORD}
mail:
login: user
password: ${MAIL_PASSWORD:-my_default_password}
sentry:
dsn: ${VAR_NOT_SET}
Then load your config:
from piny import YamlLoader
config = YamlLoader(path="config.yaml").load()
print(config)
# {'db': {'login': 'user', 'password': 'my_db_password'},
# 'mail': {'login': 'user', 'password': 'my_default_password'},
# 'sentry': {'dsn': None}}
You may want to discourage Bash-style envs with defaults in your configs. In such case, use a StrictMatcher:
from piny import YamlLoader, StrictMatcher
config = YamlLoader(path="config.yaml", matcher=StrictMatcher).load()
Both strict and default matchers produce None value if environment variable matched is not set in the system (and no default syntax used in the case of default matcher).
