This sample shows how to have a workflow interpret/invoke arbitrary steps defined in a DSL. It is similar to the DSL samples in TypeScript and in Go.
For this sample, the optional dsl dependency group must be included. To include, run:
poetry install --with dsl
To run, first see README.md for prerequisites. Then, run the following from this directory to start the worker:
poetry run python worker.py
This will start the worker. Then, in another terminal, run the following to execute a workflow of steps defined in workflow1.yaml:
poetry run python starter.py workflow1.yaml
This will run the workflow and show the final variables that the workflow returns. Looking in the worker terminal, each step executed will be visible.
Similarly we can do the same for the more advanced workflow2.yaml file:
poetry run python starter.py workflow2.yaml
This sample gives a guide of how one can write a workflow to interpret arbitrary steps from a user-provided DSL. Many DSL models are more advanced and are more specific to conform to business logic needs.
