Docker compose up errors when MySQL configuration got modified - MySQL not available. Retrying...

[nook24]

When setup a new instance, changing the MySQL credentials will break the docker compose up.

In fact, when changing one of those values from openitcockpit.env, the container startup will fail with MySQL not available. Retrying...

MYSQL_DATABASE=openitcockpit_database
MYSQL_USER=openitcockpit
MYSQL_PASSWORD=openitcockpit_password 

compose output

Changing this values works fine:

MYSQL_ROOT_PASSWORD=root_password
MYSQL_HOST=database-host

I was not able to test MYSQL_PORT

This affects version 4.8.2

To be fair, the comment says it's not recommended to change these values, how ever it should still be possible :)
