Hi

Is it possible to set the SSO url in the docker build file (YAML file) for discourse, as opposed to using console scripts or via the discourse dashboard once deployed?

I have seen articles on this site mentioning other ways of doing it, but I would like to know if this is possible via the config files and at stage the docker image is created.

Regards
