Problem installing extensions in dev mode

Hello,

I successfully setup a docker compose based dev environment. Now, I want to add some extensions to instance, but was not successfull, maybe I missed something.

I "git cloned" the extensions into the src folder (for example, the "scheming" extension). Then, I run bin/install_src and it ended up successfully:

Successfully built ckanext-scheming
Installing collected packages: ckanext-scheming
Successfully installed ckanext-scheming-3.1.0

Now, in the .env file, I changed/added (the file ckan_dataset.json lies beside the scheming extension):

CKAN__PLUGINS="image_view text_view datatables_view datastore datapusher envvars scheming_datasets"
scheming.dataset_schemas = ckanext.scheming:ckan_dataset.json

After restarting the whole docker compose stack (or using the commands in bin), the scheming is not active. Taking a look at the logs of the Docker container, I can see that it seems to use /srv/app/ckan.ini (an empty default?) as config and not the stuff from the .env file:

[prerun] Setting the following plugins in /srv/app/ckan.ini:
image_view text_view datatables_view datastore datapusher envvars

Thanks for any help!

Start by reading bin/install_src and the Docker startup output around [prerun], then compare the .env values with the generated /srv/app/ckan.ini. Reproduce the setup with ckanext-scheming, CKAN__PLUGINS, and scheming.dataset_schemas; it is done when the generated configuration includes the requested plugin and schema setting after restart.
