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:

SQL_INTERNAL_PORT=3307
SQL_CLIENT_PORT=3307
Variable SQL_INTERNAL_PORT
probably has 3307
value. You need to change it to 3306
.
Also, you can remove
expose:
- "${SQL_INTERNAL_PORT}"
lines. Mysql already exposes 3306 port.
All of the applications into cluster use internal ports (3306 in mysql case). External ports (in section ports) you need only for external word communication.
If you want to have several databases, you need to change docker-compose something like this:
version: '3'
services:
hackernews:
image: prismagraphql/prisma:1.8
restart: always
ports:
- "${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
