Configure uwsgi timeout

Asked 2021-Oct-07 at 08:07

I struggling to configure response timeout for uwsgi and the documentation isn't helpful. I have pretty long queries with hard timeout on client side so I want to drop connection before it comes to flask or have some way to check if request sits in listen queue more than some threshold because no need to answer to request which will be knowingly dropped. Also I have CPU limitation so I want to exactly X workers work at same time. On current setup with locust I got 100% failure rate after some short period of time.

This is flask app

The closest possible solution I found was from AWS Sagemaker example

Effectively solution uses nginx as rate limiter and gunicorn as load balancer. On my locust tests to avoid queue overflow, I had to add limit_req_zone with static key.

System throughput increased three order of magnitude, flask on its own is the paragon of unscalability.

Docker has internal DNS server working on 127.0.0.11 inside container. If your nginx is not in container you cannot use it to resolve myapp name. Still, you can pick one of those:

Make your container listen on host's ports:

Upgrading to Python 3.5 but uWSGI using Python 2.7

Asked 2020-Aug-26 at 19:58

I am currently trying to upgrade our Python 2.7 project to 3.5. I'm using pipenv to create a virtual environment to do this in. Our server has been upgraded to Ubuntu 16.04. In my current pip environment, when running python -V it correctly returns "Python 3.5.2". However, when attempting to start uWSGI I receive the following error:

If you have used the default venv or virtualenv to create the virtual environment you're going to use. Then you can specify the path like the following:

uwsgi -H /fullpath/to/virtualenv

Here -H is the shortcut. Documentation on this: uWSGI Options.

QUESTION

Running Flask application without nginx

Asked 2020-Jun-03 at 19:11

Running Flask application without nginx or other web server?

Can uWSGI be a web-server and application server at the same time?

For example, stand-alone WSGI Containers https://flask.palletsprojects.com/en/1.1.x/deploying/wsgi-standalone/ But again, it recommends to use an HTTP server. Why? Can't uWSGI handle HTTP requests?

I have read different articles about deploying a Flask application. They say, I'd need uWSGI and nginx - one popular option.

For running flask, you do not need nginx, just a webserver of your choice, but life with nginx is just easier. If you are using Apache, you want to consider to use a WSGI.

I remember reading somewhere in the Flask documentation what is stated by an answer to "Are a WSGI server and HTTP server required to serve a Flask app?" as

The answer is similar for "should I use a web server". WSGI servers happen to have HTTP servers but they will not be as good as a dedicated production HTTP server (Nginx, Apache, etc.).

The main idea behind is the architectural principle of splitting layers to ease debugging and increase security, similarly to the concept that you split content and structure (HTML & CSS, UI vs. API):

For the lower layers, see e.g. https://en.wikipedia.org/wiki/Transport_layer Having a dedicated HTTP server allows you to do package-filtering etc. on that level.
The WSGI is the interface layer between the webserver and the webframework.

Update

I have seen clients only running a WSGI server alone, with integrated HTTP support. Using an additional webserver and/ or proxy is just good practice, but IMHO not strictly necessary.

QUESTION

Invoking requests.get() within flask application sub-class is causing uwsgi segmentation fault and 502 on nginx

Asked 2020-Apr-27 at 21:56

I'm facing an issue with my current flask app setup and would really appreciate some input on this. Thank you!

Flow

user --> nginx --> uwsgi --> flask app --> https call to external system (response is processed and relevant data returned to client)

Workflow

Intent My flask view/route invokes another class, within which a https (GET) call is made to an external system to retrieve data. This data is then processed (analyzed) and an appropriate response is sent to the user.

Actual User receives 502 Bad Gateway from webserver upon invoking Flask Based endpoint. This is only happening when placing the nginx and uwsgi server in front of my flask application. Initial tests on the server directly with flask's in-built server appeared to work.

Note: That analytics bit does take up some time so I increased all relevant timeouts (to no avail)

Configurations

Nginx (tried with and without TLS)
