I’m trying to deploy a PHP application (Symfony 6), I attached to it a Dev Database but ever time the deployment fails and, I receive this error:

An exception occurred in the driver: SQLSTATE[HY000] [2002] No such file or directory

Hi there,

This might be caused by one of these two reasons:

The Dev databases are only Postgres and the error message indicates that your app is expecting a MySQL connection. Can you confirm if this is the case.
Your database credentials might not be using the correct environment variables. The full connection string for your database is also be available as a runtime environment variable named DATABASE_URL which you can use in your application code. You should see this it in the details for your service resource, set to a value such as:

postgres://${db.USERNAME}:${db.PASSWORD}@${db.HOSTNAME}:${db.PORT}/${db.DATABASE}

Also note that this will not be available during the build stage, so if you are running any database migrations you need to run the during the deploy stage.

Let me know how it goes!

If you are still seeing the issue, feel free to share more details on the PHP framework that you are using or the connection string that you are using.

Best,

Bobby
