kubernetes 1.16+ simple metrics-server

Download the latest components.yaml from below link:

Releases · kubernetes-sigs/metrics-server

Since metrics-server communicates by node host name, So I need hostAliases

add this hostAliases and kubelet-insecure-tls args to components.yaml

hostAliases:
      - hostnames:
        - s160
        ip: 192.19.14.160
      - hostnames:
        - s161
        ip: 192.19.14.161
      - hostnames:
        - s162
        ip: 192.19.14.162

kubectl apply -f components.yaml and wait for~15 min.

$ kubectl top node
NAME   CPU(cores)   CPU%   MEMORY(bytes)   MEMORY%   
s160   176m         4%     744Mi           19%       
s161   44m          1%     273Mi           7%        
s162   37m          0%     326Mi           8%

Done.
