Hi @Discourse  
Can I run a custom code in the app.yml file when rebuilding the app??

> <https://github.com/discourse/discourse_docker/blob/main/samples/standalone.yml>

## Any custom commands to run after building

run:

- exec:  
cd: /var/discourse  
cmd:  
- /var/discourse/rebuild/apply.sh

# Apply.sh file content:-

docker cp ./rebuild/static\_controller.rb app:/var/www/discourse/app/controllers/static\_controller.rb

docker cp ./rebuild/routes.rb app:/var/www/discourse/config/routes.rb

docker cp ./rebuild/site\_settings.yml app:/var/www/discourse/config/site\_settings.yml

./launcher restart app

Are you sure you want to overwrite those files wholesale rather than modify them?

yes @Stephen, I am sure to rewrite these files

I also run the patch command after rebuilding the app then they copy the file to docker images

# /rebuild/apply.sh

But I am curious to execute custom code in the app.yml file

I think that will do what you want.

You’d be better off solving your problem auth a plugin.
