I am trying to programmatically connect to my AWS EKS cluster using the official 
CodePudding user response：
The error message is complaining that it does not know the cluster's certificate issuer.
Your cluster object needs one of the following properties to specify the certificate authority:
caFile: Filename containing the certificate authoritycaData: Base64-encoded contents of the certificate authority file
According to the AWS documentation, you should be able to retrieve the certificate authority as "the certificateAuthority.data that was created for your cluster".
