Enable verbose logging for k8s containers

Hi, I’m experimenting with a k8s cluster created by Rancher v2.1.6 and I’m having trouble with the vSphere cloud provider which is giving me an error: "failed to provision volume for claim "default/test" with StorageClass "vcenter": No VM found"

In order to get some more info from the kube-controller-manager I would like to bump up the verbosity of the logs it is providing, lets say from the default --v=2 to --v=4. Anyone know how this can be done in Rancher?

best regards, Hreidar.
