Discourse to Discord Webhook

yeah so… me too? I am running a dockerized discourse and the app.yml file has many lines for pulling in git repos to build by the launcher… so I add

- git clone https://github.com/critcola/discourse-to-discord-webhook.git

to the app.yml file and rebuild… but it is now unclear to me how to edit the config-template.php file and save those updates to config.php when it’s all automated by the launcher build process.

why not make these settings part of a settings interface under the admin section rather than a php file edit? if that is impractical, how would one like myself modify the config.php file… do i have to enter the docker container environment and manually create the config.php file in there? does that survive updates and docker rebuilds?
