Why does docker-mysql exist?

Hi,

I've noticed that the docker-mysql folder is simply a Dockerfile which specifies a base image. This is exactly the same as specifying the image in the docker-compose.yml.

I'm just curious as to why you 'build' this dockerfile instead of just specifying the base image.

  db:
    container_name: ${DOCKER_PREFIX}_db
    # image: mysql:8.0
    # image: mysql:5.7

    # For ARM (M1) Mac
    # You need to select an image that has an OS/ARCH of arm64/v8 from
    # https://hub.docker.com/_/mysql/tags
    # On 2022-10-06 I switched the default mysql image to the oracle one which looks like it is
    # built for both AMD and ARM architectures and should compile for all platforms
    # previously, some had reported using FROM mysql/mysql-server:5.7.28 for M1 macs.
    image: mysql:8.0-oracle
#    environment:
#      user: ${APACHE_RUN_USER_ID}
    env_file: ./.env
    restart: always
    cap_add:
      - SYS_NICE  # CAP_SYS_NICE
    volumes:
      - ${MYSQL_DIR}:/var/lib/mysql
      - ${LOGS_DIR}/mysql:/var/log
#      - ${MYSQL_OVERRIDES}:/etc/mysql/mysql.conf.d
      - ${MYSQL_OVERRIDES}:/etc/mysql/conf.d
      - ${MYSQL_SCRIPTS}:/docker-entrypoint-initdb.d/
    ports:
     - 127.0.0.1:${MYSQL_PORT}:3306
    networks:
      - redcap_network

Thanks
