metrics-server

metrics-api

By default Usage is the mean from samples collected within the returned time window. The default time window is 1 minute.

如果收集不到metrics，可以尝试修改yaml文件，在args内添加配置

args:
    – /metrics-server
    – –kubelet-insecure-tls
    – –kubelet-preferred-address-types=InternalIP

操作

和上面一样

kubectl apply -f ./test/nginx-test.yaml
