[Fugitive844]

Description

After upgrading from version 1.22.5 to 1.25, the environment variable DISABLE_REGISTRATION=true does not take effect when running the Docker container. Despite setting this variable, the registration page remains accessible. This issue occurs specifically in the Docker-based installation of version 1.25.

I think DISABLE_REGISTRATION should be set in app.ini: https://docs.gitea.com/administration/config-cheat-sheet?_highlight=disable_registration#service-service.

These legacy variables (like DISABLE_REGISTRATION, without GITEA__ prefix) only take affect for first time installation.

If you have an installed instance, you need to use environment variables like GITEA__section__OPTION=xxx

Or manually edit the app.ini
