[BestChinchilla]

What environment is this in?:

On Premise in OpenStack

What did you expect to happen?:

No errors in logs every minute

What happened instead?:

We are getting a error something like this: W0822 08:38:08.999233 1 cluster_feeder.go:443] Error adding metric sample for container {{openshift-multus multus-additional-cni-plugins-ql9hs} POD}: KeyError: {{openshift-multus multus-additional-cni-plugins-ql9hs} POD} in recommender pod every minute on all system NS (openshift*, kube*, calico*, tigera-operator and etc) in OKD cluster, in these NS there's no VPA objects created and I cannot understand why VPA trying to get metrics from pods.
I'm added new arg --ignored-vpa-object-namespaces=tigera-operator,openshift,openshift-apiserver,...,argocd-operator but this not resolving the issue

How to reproduce it (as minimally and precisely as possible):

Just install VPA

Anything else we need to know?:

We are getting a error something like this: W0822 08:38:08.999233 1 cluster_feeder.go:443] Error adding metric sample for container {{openshift-multus multus-additional-cni-plugins-ql9hs} POD}: KeyError: {{openshift-multus multus-additional-cni-plugins-ql9hs} POD}

Are some of these containers sidecars?

I'm wondering if this issue is a dupe of #6691

[BestChinchilla]

@adrianmoisey I'm checked two random pods and in first of these has 2 sidecars and 0 initcontainers, but second has not both sidecars and initcontainder, but i see this pod in log error too

Sounds like the issue you're facing is this bug? #7229

[BestChinchilla]

@adrianmoisey We are not using native sidecars and we have an error in pod, that don't have any initContainer or sidecar in manifest

Can you provide more details on reproducing this?
