Update the docker-compose as to start the dashboard in development mode. The 3 containers are able to see each other.
Update the import script as to be able to find the local Elasticsearch.

By default, the ES-data is not persisted across container restarts. For this a user action is required, setting the correct access permission on the ES data folder.
