How to enable kube-system/metrics-server from status "False (MissingEndpoints)"?

Question

My metrics-server was sudden not working and got below information:

$ kubectl get apiservices |egrep metrics
v1beta1.metrics.k8s.io kube-system/metrics-server False (MissingEndpoints)

I tried to implement below but still not okay:

$ git clone https://github.com/kubernetes-incubator/metrics-server.git
$ cd metrics-server
$ kubectl apply -f deploy/1.8+/

Please advise, thanks.

Hi @4c74356b41, I tried to ran `kubectl delete -f ./deploy/1.8+/` and re-ran `kubectl apply -f deploy/1.8+/` but still failed. Any commands that I can use? — DaiKeung, Sep 01 '19 at 15:00
are you using aks or not? if you are using aks metrics server is built-in — 4c74356b41, Sep 01 '19 at 15:03
Yes, but it is suddenly gone but don't know how to make it work again. You may refer to [This link](https://stackoverflow.com/questions/57722180/why-memory-usage-is-greater-than-what-i-set-in-kubernetess-node?answertab=active#tab-top) for what I performed before.

I solved this issue the following:

Download metrics-server:

wget https://github.com/kubernetes-sigs/metrics-server/releases/download/v0.5.0/components.yaml

Remove metrics server:

kubectl delete -f components.yaml

Edit downloaded file and add - --kubelet-insecure-tls flag:

labels:
    k8s-app: metrics-server
spec:
  containers:
  - args:
    - --cert-dir=/tmp
    - --secure-port=443
    - --kubelet-preferred-address-types=InternalIP,ExternalIP,Hostname
    - --kubelet-use-node-status-port
    - --metric-resolution=15s
    - --kubelet-insecure-tls

Create service once again:

kubectl apply -f components.yaml

in this case the solution was to upgrade kubernetes version for nodes to reapply metrics server

Also, upgrading to the latest (0.4.1) version of metrics-server probably fixes similar issues (like False (MissingEndpoints)):

kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/download/v0.4.1/components.yaml;
