Kube-prometheus: Duplicate records in prometheus-rules

[chiefy]

There's duplicate records for namespace:container_cpu_usage_seconds_total:sum_rate and namespace:container_memory_usage_bytes:sum here: https://github.com/coreos/kube-prometheus/blob/master/manifests/prometheus-rules.yaml#L15-L30

Thanks for reporting! This is actually pulled in through the kubernetes-mixin dependency, we're gonna need to fix it there. Can you open an issue there? :)

Interesting. We should discuss upstream, if we need both (as the might be different) or can get rid of one after the Kubernetes metrics overhaul.
Let's discuss there.

I've filed https://github.com/kubernetes-monitoring/kubernetes-mixin/issues/230 to follow up.

This was fixed in kubernetes-monitoring/kubernetes-mixin#230, and kube-prometheus now depends on kubernetes-monitoring/kubernetes-mixin@15ddfa20a6921ffbd43172eb54f6bdc1bcf8d3d3, which includes the fix (kubernetes-monitoring/kubernetes-mixin@32c7960c8facc1e6a981587b5972050fe8bd11bf).
