 ## Debugging
 
 Directories (eg. data, postgres_data) created by running Docker Containers are probably not in your ownership. Running test scripts as a user will therefor fail to access and get permissions for those directories. If so change permissions for those directories using `sudo chmod a+rw data/`.
