使用Docker Compose在端口3307上运行MySQL

我试图在一台机器上创建多个Prisma数据库服务.我无法使用Docker Compose在3306以外的端口上创建MySQL数据库.

泊坞窗,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:

泊坞窗,compose.override.yml

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

错误：

.ENV

SQL_PASSWORD=myuniquepassword
SQL_INTERNAL_PORT=3307
SQL_CLIENT_PORT=3307

最佳答案

变量SQL_INTERNAL_PORT可能具有3307值.您需要将其更改为3306.

此外,您可以删除

    expose:
    - "${SQL_INTERNAL_PORT}"

线. Mysql已经公开了3306端口.

集群中的所有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)只需要外部字通信.

如果你想拥有几个数据库,你需要更改docker-compose这样的东西：

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
