App Specification#
Overview#
The bfabric-app-runner allows you to define and execute applications in various environments, by configuring the application steps in a YAML configuration files, the so-called app specification.
App Specification Structure#
The specification can be provided in a YAML file with the following structure:
versions:
- version: "1.0.0"
commands:
dispatch: ...
process: ...
collect: ... # Optional
Commands#
Each app defines these core commands:
dispatch: Prepares input data. Called with:$workunit_ref$work_dirprocess: Executes main logic. Called with:$chunk_dircollect: (Optional) Organizes results. Called with:$workunit_ref$chunk_dir
Commands are discriminated by their type field.
- pydantic model bfabric_app_runner.specs.app.commands_spec.CommandsSpec#
Defines the commands that are required to execute an app.

App Versions#
The AppVersionMultiTemplate class defines app versions in two ways:
Single string:
version: "1.0.0"List of strings:
version: ["1.0.0", "1.0.1"]
Variables and Templating#
Available variables for Mako templates:
${app.id}: Application ID (integer)${app.name}: Application name (alphanumeric, underscores, hyphens)${app.version}: Version string
Example:
image: "registry.example.com/${app.name}:${app.version}"
command: "/app/run.sh --app-id ${app.id}"
The interpolate_config_strings function processes all string values in the configuration after YAML loading.
Loading and Using App Specifications#
from pathlib import Path
from bfabric_app_runner.specs.app_spec import AppSpec
# Load from YAML
app_spec = AppSpec.load_yaml(Path("./app_spec.yaml"), app_id="123", app_name="MyApp")
# Check version
if "1.0.0" in app_spec:
app_version = app_spec["1.0.0"]
