Hello all,
I've developed an api using fastapi that will act as a wrapper that receives sms requests and call the sms api to send said sms and now I'm ready to deploy it. This is the code:

import logging

import uvicorn
from fastapi import FastAPI, HTTPException
from pydantic import BaseModel
from fastapi.middleware.trustedhost import TrustedHostMiddleware

import verifier

logging.basicConfig(
    format='%(asctime)s - %(funcName)s - %(levelname)s - %(message)s',
    level=logging.INFO
)

# get logger
logger = logging.getLogger(__name__)


bot_verifier = None


class DataForBot(BaseModel):
    number: str
    msg_txt: str


def get_application():
    app = FastAPI(title='bot_wrapper', version="1.0.0")

    return app


app = get_application()


@app.on_event("startup")
async def startup_event():
    global bot_verifier
    try:
        bot_verifier = await verifier.Verifier.create()
    except Exception as e:
        logger.error(f"exception occured during bot creation -- {e}", exc_info=True)


@app.post('/telegram_sender/')
async def send_telegram_msg(data_for_bot: DataForBot):
    global bot_verifier
    if not bot_verifier:
        bot_verifier = await verifier.Verifier.create()
    else:
        dict_data = data_for_bot.dict()
        try:
            if await bot_verifier.send_via_telegram(dict_data):
                return {'status': "success", 'data': data_for_bot}
            else:
                raise HTTPException(status_code=404, detail="unable to send via telegram, perhaps user has not started the bot")
        except Exception as e:
            logger.error(f"{e}", exc_info=True)
            raise HTTPException(status_code=500, detail="Something went wrong, please contact server admin")

I want to deploy it on apache b/c it's the only thing I can get my hand onto in my country. I'm using python3.8.9 with fastapi version 0.65.2 and apache/2.4.29, but for the life of me I can't get it to work. I've written an apache conf file and enabled that as such:

<VirtualHost *:80>
	ServerName gargarsa.sms.local
	ServerAdmin webmaster@localhost
	ServerAlias gargarsa.sms.local
	
	DocumentRoot /var/www/verify_bot_api/
	ServerAlias gargarsa.sms.local

	<Directory /var/www/verify_bot_api/src/app/>
		Order deny,allow
		Allow from all
	</Directory>

	ErrorLog ${APACHE_LOG_DIR}/gargarsa.sms.local-error.log
	LogLevel debug
	CustomLog ${APACHE_LOG_DIR}/gargarsa.sms.local-access.log combined
</VirtualHost>

but no avail.
I tried running gunicorn via a screen session but I couldn't access it either.
I tried running it programmatically as such but no avail:

if __name__ == "__main__":
    uvicorn.run(app, host="0.0.0.0", port=8000)

I understand this is a very broad way to ask, but I'm truly stumped.

How do I run an api built using fastapi on Apache?

Thank you for your assistance.

I remember I used "uwsgi" in emperor mode when I was running python apps under apache2. 7-8 years ago?
Not sure if that will work correctly with uvicorn/FastAPI

You could also try running it from within a docker container. And let Apache2 act as a reverse proxy.
