Open an issue to expose Docker container labels via cAdvisor prometheus metrics

One of the challenges with cAdvisor metrics is that these originate from the Node, and not many labels are available. Essentially Pod Name and Namespace, are two of the most relevant. But other labels applied to the pods themselves are not included.

When working with Auto DevOps and other components, this can make integration more difficult. We essentially have to rely on a Pod naming convention, to be able to differentiate. While discussing this it was brought up that cAdvisor likely has access to the Docker container labels, which could help address these limitations.

We should explore if we could open a issue/PR to cAdvisor to have these included in the Prometheus metrics.
