using NC_ as prefix not working

[mamema]

Hi,

i was trying to get rid of my clear text secrets in the config.php
You by yourself mentioned in the readme, that by default "a lot" can be handled via docker secret or similar in config.php.

but this:
https://github.com/nextcloud/server/blob/master/lib/private/Config.php (see ENV reference NC_) doesn't work

as the official documentation is more or less non existent on this, i'm asking, is this a issue with this image or just not working at all?

i've just tried to set env vars according to the schema

dbtype in config.php

NC_dbtype=psql in environment variables.

but this breaks with a 500 internal server error.
