Docker Compose not synchronising file changes in volume

Reposting from [here](https://forums.docker.com/t/docker-compose-not-synchronising-file-changes-in-volume/79177) as I don't quite understand how the "solution" works. **Symptom:** As reported [here](https://forums.docker.com/t/docker-compose-not-synchronising-file-changes-in-volume/79177) : I mount my local files into the container for development. My docker-compose.yml file is as follows:

version: '3.7'
services:
  node:
    build: .
    command: npm run dev
    image: node
    ports:
      - "4000:3000"
    volumes:
      - .:/code
    working_dir: /code

when I run the Next JS server in a container, it will initially load fine, but any changes made afterwards will not be shown. This is same as my observation as well. **Answers:** There has been discussion on the issues of running docker in Windows 10 Pro, but I'm hosting in Linux for Linux, and the "solution" mentioned nothing about Windows either. **Solution:** The reported working "solution" is:

version: '3.7'
services:
  node:
    build: .
    command: npm run dev
    image: node
    ports:
      - "4000:3000"
    volumes:
      - type: bind
        source: .
        target: /code
    working_dir: /code

This, to my knowledge, would be the same as what used by OP, i.e.:

volumes:
      - .:/code

I.e., I think the question of why _"docker Compose not synchronising file changes in volume"_ was not clearly answered. And neither of the following pages: - https://stackoverflow.com/questions/44678042/named-docker-volume-not-updating-using-docker-compose - https://stackoverflow.com/questions/44251094/i-want-to-share-code-content-across-several-containers-using-docker-compose-volu/44265470 - https://stackoverflow.com/questions/42958573/docker-compose-recommended-way-to-use-data-containers My case: I have a php site hosted on nginx:

version: '3.7'
services:
    web:
        image: nginx:latest
        ports:
            - "80:8081"
        volumes:
            - ./nginx.conf:/etc/nginx/conf.d/default.conf:delegated
            - ./app:/app:delegated
    php:
        build:
            context: .
            dockerfile: PHP.Dockerfile
        volumes:
            - ./app:/app:delegated
        restart: always

This is my observation: - I do docker compose up - Then ^-C to stop it - Update code in host, - Re- do / start docker compose up - Check the modified volume-mounted file within docker compose container, - The file stays the same, as before the change.
