Container image 312293e does not connect to the database

[JGillam]

Describe the bug
When building with container image tagged 312293e, the following exception occurs:
Fatal error: Uncaught mysqli_sql_exception: Connection refused in /var/www/html/dvwa/includes/dvwaPage.inc.php:508 Stack trace: #0 /var/www/html/dvwa/includes/dvwaPage.inc.php(508): mysqli_connect('127.0.0.1', 'dvwa', Object(SensitiveParameterValue), '', '3306') #1 /var/www/html/login.php(8): dvwaDatabaseConnect() #2 {main} thrown in /var/www/html/dvwa/includes/dvwaPage.inc.php on line 508

Using the previous container (1fb5078) works normally. I have not had a chance to look into why yet (I'm working with a class on this today) and plan to follow up with more details later.

To Reproduce
This is a container build issue, simply starting with the :latest container from this repo is causing the problem for me, and simply rolling back to :1fb5078 resolves it.

note: I did not provide additional detail below - but will attempt to fill in more detail later today.

Logs
Include the last five lines of the Apache log file from directly after the problem happened.

I accepted a PR this morning which changed how the database connection strings worked, I'll roll it back.

It looks like the database server is missing from the image!

I'll have a quick play but this may be above my docker skills.

[digininja]

Agreed it broke after version 1fb5078 but I can't see why.

If you can suggest anything I'll take it. The docker compose is working fine locally.

Hope the class goes well.

I believe I found the source of the problem. I build container labs for students using a template to dynamically generate compose files. It appears an expected environment variable passed through compose was renamed from DB_SERVER to DVWA_DB_SERVER.

So I can fix this on my end by updating my template. In fact, I will simply add both keys. Sorry for the fire drill.

Could you have a look at this PR that I reverted, should I put this back or not? https://github.com/digininja/DVWA/compare/master...revert-605-revert-592-env-config?expand=1
