Metricbeat on Kubernetes

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

particulary with this line:

- /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."
