Я пытаюсь создать несколько служб баз данных Prisma на одном компьютере.Мне не удалось создать базу данных MySQL на порту, отличном от 3306, с помощью Docker Compose.

docker-compose.yml 

version: '3'
services:
hackernews:
    image: prismagraphql/prisma:1.8
    restart: always
    ports:
    - "${CLIENT_PORT}:${INTERNAL_PORT}"
    environment:
    PRISMA_CONFIG: |
        port: $INTERNAL_PORT
        managementApiSecret: $PRISMA_MANAGEMENT_API_SECRET
        databases:
        default:
            connector: mysql
            host: mysql
            port: $SQL_INTERNAL_PORT
            user: root
            password: $SQL_PASSWORD
            migrations: true
mysql:
    image: mysql:5.7
    restart: always
    environment:
    MYSQL_ROOT_PASSWORD: $SQL_PASSWORD
    volumes:
    - ./custom/:/etc/mysql/conf.d/my.cnf
    - mysql:/var/lib/mysql
volumes:
mysql:

docker-compose.override.yml 

version: '3'
services:
mysql:
    expose:
    - "${SQL_INTERNAL_PORT}"
    ports:
    - "${SQL_CLIENT_PORT}:${SQL_INTERNAL_PORT}"

Переменная SQL_INTERNAL_PORT, вероятно, имеет значение 3307.Вам нужно изменить его на 3306.

Также вы можете удалить 

    expose:
    - "${SQL_INTERNAL_PORT}"

строк.Mysql уже предоставляет порт 3306.

Все приложения в кластере используют внутренние порты (3306 в случае mysql).Внешние порты (в разделе портов) нужны только для внешней передачи слов.

Если вы хотите иметь несколько баз данных, вам нужно изменить docker-compose примерно так: 

version: '3'
services:
hackernews:
    image: prismagraphql/prisma:1.8
    restart: always
    ports:
    - "${CLIENT_PORT}:${INTERNAL_PORT}"
    environment:
    PRISMA_CONFIG: |
        port: $INTERNAL_PORT
        managementApiSecret: $PRISMA_MANAGEMENT_API_SECRET
        databases:
        default:
            connector: mysql
            host: mysql_first
            port: 3306
            user: root
            password: $SQL_PASSWORD
            migrations: true
        second:
            connector: mysql
            host: mysql_second
            port: 3306
            user: root
            password: $SQL_PASSWORD
            migrations: true
mysql_first:
    image: mysql:5.7
    restart: always
    environment:
    MYSQL_ROOT_PASSWORD: $SQL_PASSWORD
    ports:
     - 3307:3306
    volumes:
    - ./custom/:/etc/mysql/conf.d/my.cnf
    - mysql:/var/lib/mysql

 mysql_second:
    image: mysql:5.7
    restart: always
    environment:
    ports:
     - 3308:3306
    MYSQL_ROOT_PASSWORD: $SQL_PASSWORD
...
