Deprecation policy

The balena SDK for Python uses semver versioning, with the concepts of major, minor and patch version releases.

The latest release of the previous major version of the balena SDK will remain compatible with the balenaCloud backend services for one year from the date when the next major version is released. For example, balena SDK v8.1.1, as the latest v8 release, would remain compatible with the balenaCloud backend for one year from the date when v9.0.0 is released.

At the end of this period, the older major version is considered deprecated and some of the functionality that depends on balenaCloud services may stop working at any time. Users are encouraged to regularly update the balena SDK to the latest version.

Developing locally

This project uses poetry for dependency management. In order to install all the needed dependencies please run poetry install.

Linting and Formatting

This project uses black for code formatting and flake8 for linting.

To format this project please use poetry run black . -l 120 To verify linting you can run poetry run flake8 --max-line-length=120

Tests

To run the tests, first create a .env file with your test user configuration, like below. Do not use credentials for a user with active fleets, as the tests may be destructive.

[Credentials]
email=[e-mail]
user_id=my_test_user
password=123456my_password

You can optionally change the target API endpoint too, e.g. api_endpoint=https://api.balena-cloud.com.

Then run poetry run python -m unittest discover tests -v. Use of poetry to run tests ensures use of its virtual environment.
