Metricbeat on Kubernetes

Hi Im having problems with the instalation of metricbeat in Kubernetes (CRC instalation of Openshift) using the manifest in the documentation:

https://raw.githubusercontent.com/elastic/beats/7.17/deploy/kubernetes/metricbeat-kubernetes.yaml

particulary with this line:

ssl.certificate_authorities:
- /path/to/kubelet-service-ca.crt

beacuse is a CRC instalation of Openshift the path are differents

where I can find the certificate? or how to create one?

according to the documentation the certificate "kubelet-service-ca.crt can be any CA bundle that contains the issuer of the certificate used in the Kubelet API."

thanks!
