kraken-core

The Kraken build system.

Kraken focuses on ease of use and simplicity to model complex task orchestration workflows.

The kraken-core packages provides a number of top-level packages under the kraken. namespace. The packages provided by this project are listed below. Other Python packages may provide additional top-level packages under this namespace.

• kraken.core – Modeling of projects, tasks and the task graph.
• kraken.cli – Provides the kraken cli.
• kraken.lib – A small set of core utility tasks (nothing language specific).
• kraken.test – Fixtures for integration-testing Kraken builds with Pytest.
• kraken.util – Utilities and helpers.
• kraken._vendor – Vendored third party libraries.

Reproducible build environments

We recommend that you use krakenw to invoke Kraken builds instead of the kraken cli directly to ensure that you have an isolated and reproducible build environment. Install the kraken wrapper cli via the kraken-wrapper package and define your build requirements at the top of your .kraken.py build script:

# ::requirements kraken-std>=0.3.0
from kraken.std.cargo import cargo_build
cargo_build()

Vendored packages

We're vendoring a number of third party packages for the purpose of reducing the burden of package resolution at installation time. This is particularly relevant for using Kraken in continuous integration systems to improve resolve times and PEX size.
