Trying to identify PODs with NO LIMITS

[Carlos Mercado]

Hi

Sorry if this is a repeated topic, but I am trying to identify all the pods with NO limits, I know there is a query to get all the pods with resources limits but this query does not return pods where limits were not set. 

What I was trying is first to get all the pods running in the cluster with query: 

sum  by (pod) (kube_pod_info)

Then I am getting the list of pods with limits set:

sum by (pod)(kube_pod_container_resource_limits{resource="cpu"})

Is there a way to compare these two results and get the list of pods with no limits?

Thanks in advance, Regards.

This should be possible with the "unless" operator:

sum by (pod) (kube_pod_info) unless sum by (pod)
(kube_pod_container_resource_limits{resource="cpu"})

Note: If you add more labels to one of the sides, you will need an
additional on(pod) clause after "unless".

Kind regards,
Christian
