[Question] How to remove AKS's metrics-server

[thiDucTran]

Describe scenario
The kube-prometheus stack includes a resource metrics API server, so the metrics-server addon is not necessary. - as stated from https://github.com/prometheus-operator/kube-prometheus

We do see there is a conflict of resource

apiVersion: apiregistration.k8s.io/v1
kind: APIService
metadata:
  labels:
    addonmanager.kubernetes.io/mode: Reconcile
    kubernetes.io/cluster-service: "true"
  name: v1beta1.metrics.k8s.io
spec:
  group: metrics.k8s.io
  groupPriorityMinimum: 100
  insecureSkipTLSVerify: true
  service:
    name: metrics-server
    namespace: kube-system
    port: 443
  version: v1beta1
  versionPriority: 100

apiVersion: apiregistration.k8s.io/v1
kind: APIService
metadata:
  labels:
    app.kubernetes.io/component: metrics-adapter
    app.kubernetes.io/name: prometheus-adapter
    app.kubernetes.io/part-of: kube-prometheus
    app.kubernetes.io/version: 0.10.0
  name: v1beta1.metrics.k8s.io
spec:
  group: metrics.k8s.io
  groupPriorityMinimum: 100
  insecureSkipTLSVerify: true
  service:
    name: prometheus-adapter
    namespace: monitoring
  version: v1beta1
  versionPriority: 100

Question

• How do we remove AKS's metrics-server? We removed the resources related to AKS's metrics-server but they keep getting re-created..I am not sure how....we tried checking from az aks addon list
• Bonus, if we cannot remove AKS's metrics-server.. how can kube-prometheus's prometheus-adapter work with AKS? There is https://github.com/Azure/AKS/blob/master/examples/kube-prometheus/README.md but I think it is quite outdated

Just disable prometheus-adapter and use metrics-server instead. They serve the same purpose, since AKS already provides metrics-server by default, don't use prometheus adapter.
