kube-state-metrics: How can I get a deployment's pods?

[Nate Rook]

Hi,

I wanted to get from a Deployment to its running Pods using some sort of label join. Getting from Pods to ReplicaSets is easy: the metric kube_pod_owner connects Pods to their ReplicaSets if they have them. But I can't find a metric with labels which let me connect ReplicaSets to Deployments: that is, there's no kube_replicaset_owner.

Has anyone had any success finding this?

Hi Nate,

We have been working on a tool named 'kubediscovery' to help with

discovering dynamic composition tree of Kubernetes Objects.

You might find it useful for your use-case.

You can find it here:

Ah, sorry, this is on me. I am specifically concerned with this problem in data which is shipped to the monitoring software Prometheus. I should have been clearer about kube-state-metrics's remit.

kubediscovery looks quite interesting!

We usually use regex to get to the pods. You can use it like so

kube_pod_info{pod=~"go-svc.*"}

 

In the above case, go-svc is the deployment name.
