Auto reloading flask server on Docker

Question

I want my flask server to detect changes in code and reload automatically. I\'m running this on docker container. Whenever I change something, I have to build and up again t

Answer 1

This is my example:

version: "3.8"

services:
  local-development:
    build:
      context: .
      dockerfile: Dockerfiles/development.Dockerfile
    ports:
      - "5000:5000"
    volumes:
      - .:/code

from flask import Flask

app = Flask(__name__)


@app.route('/')
def hello_world():
    return "hello world"


if __name__ in "__main__":
    app.run(host="0.0.0.0", port=5000, debug=True)

debug=True enables Flask to change as your code changes.

Docker already plugs into your fs events to change the code "in the container".
