Wait for db only during the OTRS install process

Why

I don't want to leave my MySQL root credentials in the ENVs for security reasons.

Problem

For some reasons the "wait_db" checks the MySQL root credentials instead of regular OTRS user. So if I remove the root credentials from ENV the OTRS never starts.

Solution

I decided to move the "wait_db" to the installation process only. Another possible approach is to create two "wait_db" functions; one for regular user and another one for root user.

root credentials are needed to create the otrs user in an empty database. you can use docker swarm secrets too.

Hi Juan. I know but it's not necessary after installation. Why can't I remove the root password after first installation?

It is also needed when restoring a backup using OTRS_DROP_DATABASE=yes, so it will not be accepted.

Ok. Thanks anyway.
