I'm having an issue on integrating Jenkins kubernetes plugin with Amazon EKS. In Jenkins plugin, which asks to provide a PKCS12 file and get connected, but in my case, I've used aws-iam-authenticator to communicate with Amazon EKS API. There is no option to add any token authentication in Jenkins config side. Further I tried to connect create a PKCS12 file, only I had ca.crt, but how can I find -inkey client.key & -in client.crt ? It's bit confusing me. Can anyone help me? I've tried following command.

openssl pkcs12 -export -out cert.pfx -inkey client.key -in client.crt -vertfile ca.crt

Or else can anyone help me on other alternative how I can authenticate Jenkins and Amazon EKS?

Thanks.
