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
