Documentation of "NC_" Environment Variables #40579
Description
There are some "NC_" environmental variables you can use instead of the "config.php" file.
Those are especially useful for docker deployments as those variables do not require manually editing of config files.
However there does not seem to be any documentation around which variables you can use and which not.
The existence of these variables is not mentioned in the official documentation.
The only mention of those that I could find from official Nextcloud sources is right in the
source code (line 86 and following) and in the pull request
It would be great to have clear documentation that those variables exist, which variables you can use and if there are any drawbacks when using those.
Tested variables in a docker compose deployment:
NC_default_language: de
NC_default_locale: de_DE
NC_default_phone_region: DE
NC_loglevel: 2
