使用DockerCompose在端口3307上运行MySQL

变量SQL_INTERNAL_PORT可能3307有价值。您需要将其更改为3306。

另外，您可以删除

    expose:
    - "${SQL_INTERNAL_PORT}"

线。Mysql已经公开了3306端口。

所有进入群集的应用程序都使用内部端口（在mysql情况下为3306）。外部端口（在部分端口中）仅用于外部字通信。

如果要拥有多个数据库，则需要更改docker-compose这样的内容：

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
