+### Docker-based deployment of the Db-Evaluator
+
+------
+
+Creates a docker container of the DBBench branch for colosseum 0.2.0
+
+TODO: create docker compose file for additonal services mariaDB 
+
+
+
+------
+
+#### Acknowledgements
+
+The Docker container is build based on the best practice guidelines of the the [docker-skeleton](https://github.com/cha87de/docker-skeleton).
