GitLab CI MySQL credentials

I’ve been trying for months now to setup a MySQL connection, to no avail. What is or where can you find that information because nowhere I’ve looked shows a valid host/database/password combo. And sitting for 5-10 min waiting for an image to build to see that minor tweak finally worked, just to see it fail for the 150th time is becoming tiresome. Even using one of the yaml templates (specifically, the one for Laravel) doesn’t help.

Please update the docs for real DB connections (SQLite is terrible if you’re creating something that’s actually going to be used and you need to be able to test on multiple instances), or if the information required to set up a CI environment already exists, make it more obvious where to find it.
