I’m attempting a local cluster to develop workloads for Portworx. I’m getting an error where the node name is not found.
What is FindMyNode() doing, and why can it not get the node name? It looks like it is talking to the API. What field is it looking for, so I can validate that I have it, or I can work on satisfying a dependency.
