+# Docker container
+
+ibt2 requires MongoDB to run.
+
+You can use docker-compose.yml to have a complete environment. Run: `docker-compose up --build`
+
+The data is stored in the *ibt2_data* volume: do not cancel it.
+
+In the *docker-tools* directory there is a set of tools to build and run another container to dump and restore the database; you need the docker-compose running, to execute them. From that directory you can:
+
+- **dump.sh**: dump the current database in a file like *ibt2-dump-2017-11-28T21:57:43.tgz*
+- **restore.sh**: *ibt2-dump-2017-11-28T21:57:43.tgz*: restore the given dump. Notice that the current database is completely removed, so DO NOT restore a dump if you don't have a backup of the current data
+- **shell.sh**: open a shell for the database
