This page describes interacting with the ChRIS Ultron Back End (CUBE) using pfurl and running an FS type plugin called pl-pacsquery. Essentially, pl-pacsquery searches a PACS for some meta information based on a pattern of command line terms, and returns results of this query in several small text/JSON files.
These result files can be consumed by downstream processing for other purposes (such as instantiating a pl-pacsretrieve plugin.
You should set an environment variable, HOST_IP to the IP of the actual host you are using. In Linux, this is
export HOST_IP=$(ip route | grep -v docker | awk '{if(NF==11) print $9}')At least one user with name/password combination as

Start CUBE from the repository source directory, running
*make*A PACS server should be accessible via IP:port to this plugin, i.e. a network path must exist between the plugin (and the host/container where it runs) and a PACS server.
In the CUBE system, we use an Orthanc container to simulate a PACS. Starting this server is out of scope of this document. See elsewhere for more information.
