You have two possibilities to use WissKI in Docker:
The all-in-one WissKI Container incorporates Drupal/WissKI, Database, Triple Store, Solr and example data in one Container and is only recommended for fast testing scenario.
The docker-compose setup respects Dockers service architecture and ships a fresh Drupal/WissKI. You have to adjust a few more settings and download the GraphDB stand alone server, but it is more robust and suitable for production.
