kdiscover

Kdiscover is a simple utility to list and configure access to all clusters it can find. The basic usecase revolves in having access to a lot of clusters but you still need to discover and export apposite kubeconfig.

Currently we suport only EKS clusters but there are plans to support othe k8s providers (GKE, AKE, etc ...)

Columns in the list :

• cluster name is the name of the cluster based on the configuration
• region region where the cluster is deployed (it is cloud specific)
• status this is reported by the cloud, if the cluster is up or in another state (modifying, down, creating ... etc)
• exported locally uses an heuristic too see if the local config already has information about this cluster
