How to add a member to an AWS managed cluster

[xushijie9]

We have asked AWS support. EKS managed clusters cannot provide the following required ca_data, cert_data, key_data. How can we join the EKS managed cluster to the federated cluster? Or is there any other solution?
$ export ca_data=$(base64 NEW_CLUSTER_CA) $ export cert_data=$(base64 NEW_CLUSTER_CERT) $ export key_data=$(base64 NEW_CLUSTER_KEY)
