FYI:
i am running container with docker and the metric from cadvisor does not have the label "pod" on my instance.

Are you running containers in k8s ?
In my setup, out of k8s, I see "name" instead of "pod".

Looks like i need to clarify. 😄
I run it on docker - not k8s.
I know that someone could run docker under the hood of k8s.

so i also have "name" instead of "pod".
