Run MySQL on Port 3307 Using Docker Compose

Question

I am trying to create multiple Prisma database services on a single machine. I have been unable to create a MySQL database on a port other than 3306 using 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}"

Error:

Answer 1

In my case I could not change the Mysql port rather than 3306 until I add MYSQL_TCP_PORT

So sample:

version: '3.8'

volumes:
  mysql_data:
    driver: local

services:
  mysql:
    image: mysql:5.7
    volumes:
      - mysql_data:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: root
      MYSQL_DATABASE: keycloak
      MYSQL_USER: keycloak
      MYSQL_PASSWORD: password
      MYSQL_TCP_PORT: 3307
    ports:
    - 3307:3307
    expose:
      - 3307
  keycloak:
    image: quay.io/keycloak/keycloak:latest
    environment:
      DB_VENDOR: MYSQL
      DB_ADDR: mysql
      DB_DATABASE: keycloak
      DB_USER: keycloak
      DB_PASSWORD: password
      DB_PORT: 3307
      KEYCLOAK_USER: admin
      KEYCLOAK_PASSWORD: Pa55w0rd
      # Uncomment the line below if you want to specify JDBC parameters. The parameter below is just an example, and it shouldn't be used in production without knowledge. It is highly recommended that you read the MySQL JDBC driver documentation in order to use it.
      #JDBC_PARAMS: "connectTimeout=30000"
    ports:
      - 8040:8080
    depends_on:
      - mysql
