⚙️ Installation
poetry self add poetry-plugin-dotenv
👩🏻💻 Usage
By default, plugin will load the .env
file from the current working directory or "higher directories".
To prevent poetry
from loading the dotenv file, set the POETRY_DONT_LOAD_DOTENV
environment variable.
If your dotenv file is located in a different path or has a different name you may set the POETRY_DOTENV_LOCATION
environment variable.
# .env
DB__HOST=localhost
DB__DBNAME=prod
DB__USER=admin
DB__PASSWORD=admin
DB__ENGINE=postgresql://${DB__USER}:${DB__PASSWORD}@${DB__HOST}/${DB__DBNAME}
# .env.dev
DB__HOST=localhost
DB__DBNAME=dev
DB__USER=root
DB__PASSWORD=root
DB__ENGINE=postgresql://${DB__USER}:${DB__PASSWORD}@${DB__HOST}/${DB__DBNAME}
# main.py
import os
if __name__ == "__main__":
try:
print(f"Host: {os.environ['DB__HOST']!r}")
print(f"Name: {os.environ['DB__DBNAME']!r}")
print(f"Username: {os.environ['DB__USER']!r}")
print(f"Password: {os.environ['DB__PASSWORD']!r}")
print(f"Engine: {os.environ['DB__ENGINE']!r}")
except KeyError:
print("Environment variables not set!")
poetry run -vvv python main.py
# Loading environment variables from '.env'.
# Host: 'localhost'
# Name: 'prod'
# Username: 'admin'
# Password: 'admin'
# Engine 'postgresql://admin:admin@localhost/prod'
export POETRY_DOTENV_LOCATION=.env.dev && poetry run -vvv python main.py
# Loading environment variables from '.env.dev'.
# Host: 'localhost'
# Name: 'dev'
# Username: 'root'
# Password: 'root'
# Engine 'postgresql://root:root@localhost/dev'
export POETRY_DONT_LOAD_DOTENV=1 && poetry run -vvv python main.py
# Not loading environment variables.
