django container crashes: missing dependency elasticsearch

[dubst3pp4]

Hello, I'm new to GeoNode development and just followed your instructions to build docker containers to run a development version of GeoNode. Unfortunately the django and celery containers constantly crash because of a missing elasticsearch dependency:

I've build the images with

docker-compose -f docker-compose.development.yml -f docker-compose.development.override.yml build --no-cache

and started the containers with

docker-compose -f docker-compose.development.yml -f docker-compose.development.override.yml up

Am I missing something?
