when trying to use tridentctl (macos version) I get the following error.
./tridentctl -n trident create backend -f backend.json
Error: error communicating with Trident REST API; Post "http://127.0.0.1:8000/trident/v1/backend": EOF
command terminated with exit code 1
This is for an EKS cluster. Trident being run from a MAC not in AWS. Kubectl works fine.

True, but I'm pretty certain tridentctl also looks there by default. At least it did when I last had to use it 🤷 But you're right it's still a good idea to double-check

but also, working with the CRD's, as you said, will also work
