I successfully set up the node-red starter on my IBM/BlueMix account. However, during the creation I did not have the choice to use a new Cloudant NoSQL DB instance (I guess this is where node-red stores its settings, and if I look at it via the web ui of IBM/BlueMix, I can indeed see only one database in it called "nodered"). I already had a Cloudant NoSQL DB instance which I want to use to centralize all my data.
How can I move the installed node-red to this Cloudant NoSQL DB instance?
Or did I overlook some setting during creation of the node-red that makes it possible during creation to point to an already existing Cloudant NoSQL DB instance?
The Node-RED instance deployed by the boilerplate has a small wrapper which sets up the storage of flows and other settings in the Cloudant instance. The boilerplate creates a Cloudant instance as part of the install.
You can override the Cloudant instance by binding the new instance to the Node-RED instance and then setting the following environment variable to the name of the Cloudant instance:
NODE_RED_STORAGE_NAME=<Cloudant Instance Name>
