cm-service

This is the Rubin Observatory data processing campaign management ReST service. cm-service is developed with FastAPI and Safir. Learn more at https://cm-service.lsst.io.

Developer Quick Start

You can build and run cm-service on any system which has Python 3.10 or greater, make, and Docker w/ the Docker Compose V2 CLI plugin (this includes, in particular, recent MacOS with Docker Desktop). Proceed as follows:

  • Establish and activate a Python 3.10 environment (e.g. with conda create ... or python3 -m venv ...).

  • Install Python dependencies and activate pre-commit hooks with make init.

  • Spin up a debug instance of the service running in the foreground of the current shell with make run. This will launch a subsidiary Postgres instance locally in a Docker container via Docker Compose. The foreground debug service instance will log to stdout and will dynamically reload as you edit and save source files.

  • Access the monitoring web application at http://0.0.0.0:8080/web_app/campaigns/

  • Exit your debug instance with ^C. The subsidiary Postgres and Redis containers launched under Docker Compose will remain active, and will be re-used on any subsequent make run

  • Shut down the subsidiary Postgres container if/when desired with docker compose down. Database state will be maintained in local Docker volumes and re-used on the next run. If you wish to clear the database state volumes as well to start completely fresh, do docker compose down -v.

Additional developer conveniences:

  • Browse the integrated online ReST API documentation while the service is running at http://localhost:8080/cm-service/v1/docs.

  • Run the pytest test suite at any point with make test. This will launch subsidiary containers if necessary via Docker Compose, or will make use of any that may already be running. Tests are performed in their own Postgres schema, so as not interfere with debugging state in a running debug service instance.

  • To run the playwright tests, add --run-playwright to the pytest arguments

  • Run the pre-commit hooks to lint and reformat your code via make lint.

  • Run the mypy static type hint checker with make typing.
