Installing Metrics Server

Mac

kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml && kubectl patch deployment metrics-server -n kube-system --type='json' -p='[{"op": "add", "path": "/spec/template/spec/containers/0/args/-", "value":"--kubelet-insecure-tls"}]'

Windows (Powershell)

kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml && kubectl patch deployment metrics-server -n kube-system --type='json' -p='[{"op": "add", "path": "/spec/template/spec/containers/0/args/-", "value":"--kubelet-insecure-tls"}]'

Windows (CMD)

If you are using Windows CMD, you will need to enter these two commands separately. The first command installs all the necessary components for the Metrics Server:

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

The second command specifically patches the deployment manifest to add the --kubelet-insecure-tls flag to the Metrics Server configuration:

kubectl patch deployment metrics-server -n kube-system --type="json" -p="[{\"op\": \"add\", \"path\": \"/spec/template/spec/containers/0/args/-\", \"value\":\"--kubelet-insecure-tls\"}]"

Hands-on debugging session: instrument, monitor, and fix

Join Lazar for a hands-on session where you’ll build it, break it, debug it, and fix it. You’ll set up Sentry, track errors, use Session Replay and Tracing, and leverage some good ol’ AI to find and fix issues fast.
