I use docker for MySql and Adminer interface, the connection between Adminer and MySql works but the Symfony connection is refused. Symfony isn't in a container.
What can i do for the connection between Symfony 4 and MySql container works ?
this is my docker-compose.yml :
version: '3'
services:
mysql:
image: mysql:5.7
volumes:
- ./data:/var/lib/mysql
environment:
MYSQL_ROOT_PASSWORD: "rootpwd"
MYSQL_USER: 'testuser'
MYSQL_PASSWORD: 'testpassword'
adminer:
image: adminer
restart: always
ports:
- 8080:8080
links:
- mysql:db
volumes:
mysql:
my .env on symfony 4:
# This file defines all environment variables that the application needs.
# DO NOT DEFINE PRODUCTION SECRETS IN THIS FILE.
# Use ".env.local" for local overrides during development.
# Use real environment variables when deploying to production.
# https://symfony.com/doc/current/best_practices/configuration.html#infrastructure-related-configuration

# Format described at http://docs.doctrine-project.org/projects/doctrine-dbal/en/latest/reference/configuration.html#connecting-using-a-url

# Configure your db driver and server_version in config/packages/doctrine.yaml
DATABASE_URL=mysql://testuser:[email protected]:3306/dbname

and my doctrine.yml :

# You should not need to change this value.

UPDATE
Well, thanks for your help it works, Symfony or more especially doctrine not found the container, like you said I exposed the Mysql port, but I have to make an other change : This line works for me :
DATABASE_URL=mysql://root:[email protected]:3306/dbname
and not this line :
DATABASE_URL=mysql://testuser:[email protected]:3306/dbname
In fact it seems like that my docker-compose up doesn't work very well and compose with old version, docker doesn't "see" my change on docker-compose.yml, so the password and user stay "root". I'm going to try this : https://forums.docker.com/t/how-to-delete-cache/5753/2 and this: https://github.com/docker/compose/issues/1487
Sometimes, database need to be delete => Warning: the Docker specific variables will only have an effect if you start the container with a data directory that is empty; any pre-existing database will be left untouched on container startup. https://hub.docker.com/_/postgres/
You need to expose database port like eg.
version: '3'
services:
mysql:
image: mysql:5.7
volumes:
- ./data:/var/lib/mysql
environment:
MYSQL_ROOT_PASSWORD: "rootpwd"
MYSQL_USER: 'testuser'
MYSQL_PASSWORD: 'testpassword'
ports:
- 3306:3306
adminer:
image: adminer
restart: always
ports:
- 8080:8080
links:
- mysql:db
volumes:
mysql:
and then in .env
file
DATABASE_URL=mysql://testuser:[email protected]:3306/dbname
Make sure that the ip address matches the IP of your docker host.
