@clubanderson I am not sure how would i check the entire flow for remote clusters....also for local testing kind does not OCM ...can you help me how can i get OCM enabled cluster in my local any dummy cluster .

I will use that cluster for testing the entire flow .

[clubanderson]

yes, you have the ocm command you need to use to join a remotely cluster. It is part of the pre-req

[clubanderson]

to install OCM CLI

curl -L https://raw.githubusercontent.com/open-cluster-management-io/clusteradm/main/install.sh | bash

[clubanderson]
