uninstall prometheus-adapter #557

Closed runningman84 closed 9 months ago

runningman84 commented 1 year ago

What happened?: We have uninstalled the prometheus adapter in a cluster. Now we get error messages like this:

E0125 12:04:01.326930      32 memcache.go:255] couldn't get resource list for [external.metrics.k8s.io/v1beta1](http://external.metrics.k8s.io/v1beta1): Got empty response for: [external.metrics.k8s.io/v1beta1](http://external.metrics.k8s.io/v1beta1) schauen

What did you expect to happen?:

Uninstall of the helm chart should remove it from the system.

Anything else we need to know?:

I would just like to know how to purge prometheus-adapter from a given cluster.

Environment:

prometheus-adapter version: na
prometheus version: na
Kubernetes version (use kubectl version): 1.23
Cloud provider or hardware configuration: AWS EKS
Other info:

Hi @runningman84,

Could you please confirm that kubectl get apiservices v1beta1.external.metrics.k8s.io returns a NotFound error?

I suppose the error message you mention is in the API server logs? Did you try to restart the API server after uninstalling prometheus-adapter?

I guess it is related to https://github.com/kubernetes-sigs/custom-metrics-apiserver/issues/146

yes:

Your last comment shows that v1beta1.external.metrics.k8s.io is provided by KEDA, not by prometheus-adapter. Could you please give a little more information on your issue?

The log message in your first comment does not show if the error refers to KEDA or prometheus-adapter.
