Kubernetes Metrics Server

This is a copy of components.yaml release v0.6.4 GitHub, with a minor change in Deployment -> Template -> Container['metrics-server'] -> args: --kubelet-insecure-tls=true

Installation

Can be installed directly from a copy stored here locally:

kubectl apply -f metrics-server/components.yaml

or directly from github:

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

or via helm charts:

helm repo add metrics-server https://kubernetes-sigs.github.io/metrics-server/
helm upgrade --install metrics-server metrics-server/metrics-server

The latter 2 options may not start up (did not for me) and metrics pod complained with logs:
