Cannot create MySQL database

[AlbertoNessi]

Hi everyone!

I'm on a Macbook Air M2 2022 and i'm trying to create the database with MySQL instead of PostgreSQL, but when i run:

docker compose exec php bin/console dbal:run-sql -q "SELECT 1" && echo "OK" || echo "Connection is not working"

I get:

In ExceptionConverter.php line 101:
  An exception occurred in the driver: SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo for database failed: Name or service not known
...
Connection is not working.

And sometimes this:

Error response from daemon: Container <container_id> is restarting, wait until the container is running
Connection is not working

If i run:

docker-compose logs database

i get:

Creating a "symfony/skeleton " project at "./tmp"
container_name-database-1  |
container_name-database-1  | In CreateProjectCommand.php line 388:
container_name-database-1  |
container_name-database-1  |   Invalid stability provided (), must be one of: stable, RC, beta, alpha, dev

These are my edits from PostgreSQL, I followed the guide of this project obviously: Using MySQL

• In my Dockerfile i added this line:

RUN install-php-extensions pdo_mysql

What can i do to fix this? I seem to be configuring everything correctly.

Thanks in advance!

Commenting this block fixes the issue on my side: https://github.com/dunglas/symfony-docker/blob/main/frankenphp/docker-entrypoint.sh#L33-L37

It looks like Doctrine returns a 255 status code when failing to connect to MySQL. It's not the case for Postgres. Maybe should we tweak or comment this check?
