Apache Configuration and dereferencing

In graphdb/config.yml it is possible to configure the basic information about the database server, as well as the list of base paths to dereference (more details about the used tool and syntax).

Running the following script (requires NodeJS installed)

npx list2dereference graphdb/config.yml

2 files will be produced:

• kflow.eurecom.fr.conf is the configuration file for Apache and saved in /etc/apache2/sites-available/
• script_graphdb.sh should be run inside the Docker container using docker exec -it kflow_graphdb bash

This procedure should be repeated when new base paths for dereferencing are needed
