I'm very new to Python.
I'm making a simple web server with fastapi and uvicorn.
When I build my Docker and run it, I have the following:
INFO: Started server process [1]
INFO: Waiting for application startup.
INFO: Application startup complete.
INFO: Uvicorn running on http://127.0.0.1:5000 (Press CTRL+C to quit)
My code is:
# Setup FastAPI server
import uvicorn
from fastapi import FastAPI
from fastapi_utils.tasks import repeat_every
from fastapi.middleware.cors import CORSMiddleware
from dotenv import load_dotenv
import os
from pymongo import MongoClient
import logging
logger = logging.getLogger(__name__)
logger.setLevel(logging.DEBUG)
load_dotenv('env')
# Database
CONNECTION_URL = os.environ['mongoConnectionURL']
DATABASE_NAME = os.environ['mongoDatabaseName']
NEWS_COLLECTION = os.environ['mongodbNewsCollection']
app = FastAPI()
# TODO JS has next function i'm currently unaware of
app.add_middleware(
CORSMiddleware,
allow_origins=['*'],
allow_headers=["Origin, X-Requested-With, Content-Type, Accept"],
)
@app.get('/')
def index():
return 'See /entries'
@app.get('/entries')
def getEntries():
client = MongoClient(CONNECTION_URL)
databaseMongo = client.get_database(DATABASE_NAME)
collectionMongo = databaseMongo.get_collection(NEWS_COLLECTION)
result = list(collectionMongo.find())
for entry in result:
return {
'data': result
}
if __name__ == "__main__":
uvicorn.run(app, port=int(os.environ['PORT']))
My Dockerfile is:
# Python container
FROM python:3.9.12
# Copy the source code to the container
COPY env /env
COPY main.py /main.py
COPY requirements.txt /requirements.txt
# If container is run in debug mode, we need to add the image folder
RUN mkdir /img
# Install requirements
RUN pip install --upgrade pip && pip install -r requirements.txt
CMD ["python", "main.py"]
I run my docker file as:
docker run memeified-docker-server
When I access the http://127.0.0.1:5000, the browser displays the ERR_CONNECTION_REFUSED page.
