Docker卷和Drupal

Question

我在Docker上做了一个Drupal项目。我从官方图片开始。我做了这样的docker-compose：

version: "3"

services:
  nginx:
    build:
      context: docker/nginx
      dockerfile: Dockerfile
    volumes:
      - drupal:/var/www/html
    ports:
      - 80:80
    env_file:
      - ./docker/env/nginx.env
    command: /bin/bash -c "sh /build_vhost.sh"

  cli:
    build:
      context: docker/cli
      dockerfile: Dockerfile
      args:
        DOCKER_UID: ${DOCKER_UID} # replace by your user id
        DOCKER_GID: ${DOCKER_GID} # replace by your group id
    volumes:
      - drupal:/var/www/html
    working_dir: /var/www/html
    env_file:
      - ./docker/env/mysql.env

  drupal:
    build:
      context: docker/drupal
      dockerfile: Dockerfile
      args:
        DOCKER_UID: ${DOCKER_UID} # replace by your user id
        DOCKER_GID: ${DOCKER_GID} # replace by your group id
    volumes:
      - drupal:/var/www/html
    working_dir: /var/www/html
    restart: always

  mariadb:
    image: mariadb:10.4-bionic
    ports:
      - 3306:3306
    volumes:
      - ./docker/volumes/mariadb/databases:/var/lib/mysql
    env_file:
      - ./docker/env/mysql.env
volumes:
    drupal:

而且可行，我在容器nginx，cli和drupal中有Drupal文件。 但是，如果我将其修改为在项目中包含文件，则如下所示：

version: "3"

services:
  nginx:
    build:
      context: docker/nginx
      dockerfile: Dockerfile
    volumes:
      - ./drupal:/var/www/html
    ports:
      - 80:80
    env_file:
      - ./docker/env/nginx.env
    command: /bin/bash -c "sh /build_vhost.sh"

  cli:
    build:
      context: docker/cli
      dockerfile: Dockerfile
      args:
        DOCKER_UID: ${DOCKER_UID} # replace by your user id
        DOCKER_GID: ${DOCKER_GID} # replace by your group id
    volumes:
      - ./drupal:/var/www/html
    working_dir: /var/www/html
    env_file:
      - ./docker/env/mysql.env

  drupal:
    build:
      context: docker/drupal
      dockerfile: Dockerfile
      args:
        DOCKER_UID: ${DOCKER_UID} # replace by your user id
        DOCKER_GID: ${DOCKER_GID} # replace by your group id
    volumes:
      - ./drupal:/var/www/html
    working_dir: /var/www/html
    restart: always

  mariadb:
    image: mariadb:10.4-bionic
    ports:
      - 3306:3306
    volumes:
      - ./docker/volumes/mariadb/databases:/var/lib/mysql
    env_file:
      - ./docker/env/mysql.env

Drupal文件不在容器中，而是卷工作：如果我在容器中创建文件，则将其保存在本地文件系统中。在建立映像之前，该目录已存在，我在其上放置了777个权限。

在构建中显示Drupal文件已下载并解压缩时的输出。

我不更改两个版本的docker-compose之间的Dockerfile。

请问如何在本地文件系统上保存Drupal文件以对更改进行版本控制？
