flask-py-db

A simple Flask Python CRUD app to understand how the basics of CRUD works with a database

run locally

Use the .devcontainer to run the program inside of .devcontainer.

version: '3.8'

services:
  app:
    image: sangam14/flask-crud:latest  # Assuming this is the image with everything set up
    restart: unless-stopped
    ports:
      - "5100:5000"  # Exposing the Flask app on port 5100 externally. Reminder the logic is HOST:CONTAINER. The container port has to be 5000 as the build image we set it as 5000 in the dockerfile.

      - db
