I've installed metrics-server on kubernetes v1.11.2.
I'm running a bare-metal cluster using 3 nodes and 1 master
In the metrics-server log I have the following errors:
E0907 14:29:51.774592 1 manager.go:102] unable to fully collect metrics: [unable to fully scrape metrics from source kubelet_summary:vps01: unable to

E0907 14:30:10.517886 1 reststorage.go:112] unable to fetch node metrics for node "vps01": no metrics known for node "vps01"
I also can't get any metrics using kubectl top node vps01
Same for autoscale it is not working
unable to get metrics for resource cpu: unable to fetch metrics from
resource metrics API: the server could not find the requested resource (get pods.metrics.k8s.io)
Once you deploy and log in to Kubernetes Dashboard, you'll have access to metric summaries for each pod, node, and namespace in your cluster. You can also use the UI to edit Kubernetes objects—for instance, to scale up a Deployment or to change the image version in a pod's specification.
I found the following solution:
Change the metrics-server-deployment.yaml
file and add:
command:
- /metrics-server
- --kubelet-preferred-address-types=InternalIP
- --kubelet-insecure-tls
