bfabric-app-runner

The app runner is an experimental tool that standardizes the integration of one-off apps into B-Fabric.

The API is subject to drastic changes in the next time.

The main idea is that an app provides a specification of the following steps:

dispatch -> create inputs.yml files and 1 chunks.yml file
process -> process a particular chunk (after inputs have been prepared)
collect -> collect the results of a chunk and create outputs.yml files

The individual app can be in a container environment or a script running in the same environment as the app runner.

To make this possible input and output staging is abstracted and communicated through inputs.yml and outputs.yml specification files. A command is available to stage the inputs or register the outputs respectively then.

Quick Start

See the examples/ directory for templates and detailed instructions on creating new applications. Start with development mode for testing, then build for production after updating the version in pyproject.toml.
