Making config file location configurable via env variable

[mjknowles]

Apologies if I needed to submit this as an idea first, but I thought others could potentially find this useful. If the environment variable is not provided, then the application will default to expecting the config file at the ROOTPATH.

More detail:

I created this feature in a fork so that I can mount a config file stored in Azure File Storage as a volume in my container in an Azure App Service. Azure currently requires users to mount the entire storage container as a volume (instead of just mounting an individual file), therefore I wasn't able to mount it to /var/wiki since it would hide all the existing files.

My docker-compose file can now look like:

version: "3" services: wikijs: image: ports:

• "80:80" environment: WIKI_ADMIN_EMAIL: CONFIG_PATH: /var/wiki/config volumes:
• :/var/wiki/config
