Installation (quick start)

Simplified steps to install and use the orchestrator-core. For more details, read the Getting started documentation.

Step 1 - Install the package

Create a virtualenv and install the orchestrator-core.

python -m venv .venv
source .venv/bin/activate
pip install orchestrator-core

Step 2 - Setup the database

Create a postgres database:

createuser -sP nwa
createdb orchestrator-core -O nwa  # set password to 'nwa'

Configure the database URI in your local environment:

export DATABASE_URI=postgresql+psycopg://nwa:nwa@localhost:5432/orchestrator-core

Step 3 - Create main.py and wsgi.py

Create a main.py file for running the CLI.

from orchestrator.core.cli.main import app as core_cli

if __name__ == "__main__":
    core_cli()

Create a wsgi.py file for running the web server.

from orchestrator.core import OrchestratorCore
from orchestrator.core.settings import AppSettings

app = OrchestratorCore(base_settings=AppSettings())
app.register_graphql()

Step 4 - Run the database migrations

Initialize the migration environment and database tables.

python main.py db init
python main.py db upgrade heads

Step 5 - Run the app

export OAUTH2_ACTIVE=False
uvicorn --reload --host 127.0.0.1 --port 8080 wsgi:app

Contributing

We use uv to manage dependencies. Unit tests need no services; integration tests use testcontainers to spin up Postgres + Redis on demand (Docker required).

To get started, follow these steps:

# on your local machine
git clone https://github.com/workfloworchestrator/orchestrator-core
cd orchestrator-core
just pytest                              # Run unit tests
just pytest test/integration_tests       # Run integration tests (testcontainers)
just pytest -vx                          # Stop at first failed test
just pytest --last-failed                # re-run only failed tests
