1.2.0 (2025-05-30)
Features
- major internal migration from Flask and Gunicorn to FastApi and Uvicorn (a062184)
- removed global variable init_container_names and moved the logic to util.metrics module leveraging registered metric labels as initial containers
- no more new docker client per request!
- handed over the event loop and task scheduling management to FastApi + Uvicorn
Notes
- No changes to Prometheus metrics endpoints, names, labels, or scrape behavior.
- Existing Prometheus scrapers, dashboards, and alerting rules will continue to work as-is.
- The internal implementation is now fully asynchronous with FastAPI, potentially improving concurrent scrape handling under heavy load.
- Logging and startup messages will differ due to the new framework and ASGI server (
uvicorn).
- adjust the following settings for
uvicorn as environment variables:
- HOST
- PORT
- WORKERS (Default : 3)
- LOG_LEVEL=(Default : warning)
⚠️ Breaking operational change: if your deployment or runtime environment specifically depends on Flask or Gunicorn, you'll need to adjust service definitions accordingly.
