Configuring OpenID when running from Docker?

[proffalken]

Hello,

I've started using Alf.io this week and it's fantastic!

I'd like to add OpenID support to the platform, however I can't see how I do this if I'm running Alf.io within Docker when I read the docs at https://alf.io/docs/configuration/openid/

Presumably I need to insert this file somewhere into the container, but I'm slightly surprised given how advanced the platform is in other areas that I can't do this via the UI?
