## Description

Python Flask web applications running with **Meinheld** controlled by **Gunicorn** have some of the [best performances achievable by Flask](https://www.techempower.com/benchmarks/#section=test&runid=a979de55-980d-4721-a46f-77298b3f3923&hw=ph&test=fortune&l=zijzen-7) (*).

If you have an already existing application in Flask or are building a new one, this image will give you the best performance possible (or close to that).

This image has an "auto-tuning" mechanism included, so that you can just add your code and get **good performance** automatically. And without making sacrifices (like logging).

You can read more about these ideas in the [FastAPI documentation about: FastAPI in Containers - Docker](https://fastapi.tiangolo.com/deployment/docker/#replication-number-of-processes) as the same ideas would apply to other web applications in containers.

[Meinheld](https://github.com/mopemope/meinheld) has not been actively maintained in the past years.

The current latest version of Meinheld released is 1.0.2, from May 17, 2020. This version of Meinheld requires an old version of Greenlet (`>=0.4.5,<0.5`) that is not compatible with Python 3.10 and 3.11, the last version compatible was Python 3.9.

[Python 3.9 now reached its End Of Life](https://devguide.python.org/versions/). So, there is currently no feasible way to use this Docker image.

Additionally, most of my time is now dedicated to [FastAPI](https://fastapi.tiangolo.com/) and friends.

Because of all that, this Docker image is no longer supported. ☕
