If you already have an Enterprise trial version of DSS you should already have your license.json. Please note that the Free Community edition does include the Real-time prediction API nodes.
1) The license.json is under in DATA_DIR/config/license.json on the design node.
2) The URL would need to be the IP/URL where the API node can be reached from the API deployer. For example http://IP-OR-URL:PORT
That URL you access the API node with does not need to be the same you can use a public or add a reverse proxy in front the API nodes as needed so other applications can reach the API nodes.
For a practical example please see: https://knowledge.dataiku.com/latest/courses/o16n/real-time-deployment/deploy-realtime.html
Hope this helps!
I used same license.json file from DATA_DIR/config/
I am getting following error:
Executing following command:
dataiku-dss-9.0.1/installer.sh -t api -d /home/ubuntu/dir_created/ -p 9100 -l /home/ubuntu/DATA_DIR/config/license.json
which says license does not cover API node usage
Just to clarify the Free edition with Advanced feature (trial) which you activate from DSS "Start 2 Week Trial" does include an API node trial.
To get access to a license that includes the ability to please contact us via https://www.dataiku.com/home/contact-us/.
One of our representatives will be in touch in order to set up your full DSS Enterprise evaluation and this new license will allow the installation of API nodes.
