App service won't run my Docker via python

Question

This is how I used VS code to upload my images to Azure. and upload two version of it. But when I have to have the App Service make use of Docker that I have uploaded, it gets the name but it just doesn't come up and run at all. Is it because I'm missing something for it to work?

Dockerfile:

FROM python:3.8

COPY service/clubs.py /app/service/clubs.py
COPY service/commands.py /app/service/commands.py
COPY service/logger.py /app/service/logger.py
COPY service/task.py /app/service/task.py
COPY service/layout.py /app/service/layout.py
COPY service/helpers.py /app/service/helpers.py

RUN pip install discord
CMD ["python", "index.py"]

Docker-compose:

version: '3'
services:
  web:
    container_name: "fmbotdiscord"
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - "5000:5000"
    volumes:
      - ./index.py:/app/index.py

Answer 1

@Jesper Petersen Regarding the issue you are facing, the suggestion provided by @Ben Gimblett mentioned is correct (Thank you Ben). You need to specify the port that your application is listening on in the Azure App Service configuration. By default, Azure App Service listens on port 80 for HTTP traffic and port 443 for HTTPS traffic. If your application is listening on a different port, you need to specify it in the configuration.

To specify the port, you can set the WEBSITES_PORT environment variable in the Azure App Service configuration. You can do this using the Azure Portal or the Azure CLI. Here is an example of how to set the WEBSITES_PORT environment variable using the Azure CLI:

az webapp config appsettings set --resource-group <resource-group-name> --name <app-name> --settings WEBSITES_PORT=5000

Replace <resource-group-name> with the name of your resource group and <app-name> with the name of your app service.

After setting the WEBSITES_PORT environment variable, you should be able to access your application on Azure App Service using the URL http://<app-name>.azurewebsites.net:<port>, where <app-name> is the name of your app service and <port> is the port that your application is listening on.

Let me know if you have any other questions.

Hi - thanks for the question
One thing to check here (as you're not using standard http port) is that you tell app service which port to forward to
