docker php container and local composer issue

问题

well I was using wamp-server on windows 10 for a long time and that was fine but now I want to go for docker and use its benefits. problem is I want to use my docker PHP interpreter on my local machine so according to this question:

set PHP path from host to docker container

I've found a solution to use something like this:

docker exec -i php73_fpm php %*

in a php.bat file, place it in a directory and add it to environment variables and that looks fine. when i hit php -v it shows me the version that i have on docker not locally so that should be fine. until i tried to use composer. and as soon as i hit php composer in a CMD window, it shows an error saying:

Could not open input file: C:\ProgramData\ComposerSetup\bin\composer.phar

this is because i changed php.exe path to php.bat i assume? and composer is expecting php.exe path in environment variables? how can i force composer to use my docker PHP container not the locally installed one?

EDIT: i will post my docker-compose.yml content here in case that might be needed:

version: '3'

networks:
  web_server:
    driver: bridge

services:

  nginx:
    image: nginx
    container_name: nginx_server
    ports:
      - "80:80"
      - "443:443"
    depends_on:
      - php
      - couchbase
    command: [nginx-debug, '-g', 'daemon off;']
    restart: unless-stopped
    tty: true
    volumes:
      - ./docker/nginx/logs:/var/log/nginx
      - ./docker/nginx/sites:/etc/nginx/conf.d
      - ./src:/usr/share/nginx/html
    networks:
      - web_server

  php:
    container_name: php73_fpm
    build:
      context: ./docker/php-fpm
      dockerfile: Dockerfile
    working_dir: /usr/share/nginx/html
    restart: unless-stopped
    tty: true
    environment:
      SERVICE_NAME: php73-fpm
      SERVICE_TAGS: dev
    ports:
      - "9000:9000"
    environment:
      - COUCHBASE_HOST=couchbase
      - COUCHBASE_BUCKET_NAME=default
      - COUCHBASE_BUCKET_PASSWORD=
    volumes:
      - ./src:/usr/share/nginx/html
    networks:
      - web_server

  couchbase:
    image: couchbase
    container_name: couchbase
    ports:
        - 8091:8091
        - 8092:8092
        - 8093:8093
    volumes:
      - ./docker/couchbase:/opt/couchbase/var
    restart: unless-stopped
    tty: true
    networks:
      - web_server

回答1:

First of all this answer is inspired by @soju suggestion about installing composer on the container itself.

well turned out I should have forget my local composer and install it to my container. so i installed it using this line in my php containter's Dockerfile:

RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

then i should have remove composer directories from environment variables, these directories are:

C:\Users\[windows-username-here]\AppData\Roaming\Composer\vendor\bin
C:\ProgramData\ComposerSetup\bin\composer.phar

create another composer.bat file and place it somewhere with this content:

docker exec -i php73_fpm composer %*

add file path to environment variables. and thats it.

now when i use composer require something it will send my command to the php73_fpm docker container and do the job. but there should be a volume for the folder that i would use in the docker-compose.yml file so when it creates the composer.json it would place it in that directory on local machine.
