LAB 13.3: Adding tools for monitoring and metrics - Metrics API not available after 10+ minutes

I'm hands on with lab 13.3, at step 6 I've done everything with no issues (and I've already check twice every step); but in step 7 after 15 minutes waiting for a different output from the command "kubectl top pod" or "kubectl top nodes", I'm still getting the same:
error: Metrics API not available
Can anybody help me telling me if there is something missing in instructions?
Thank you in advance.

Hi @juanalmaraz,
From your
metrics-server
deployment, can you provide the code snippet representing the containerargs
and theimage
, similar to the snippet shown in Lab 13.3 step 5 of the lab guide? Typically typos in this section can cause issues with themetrics-server
.Regards,

@chrispokorni I've got the same problem. This is the kubectl -n kube-system describe deployment metrics-server :
Containers: metrics-server: Image: k8s.gcr.io/metrics-server/metrics-server:v0.3.7 Port: 4443/TCP Host Port: 0/TCP Args: --cert-dir=/tmp --secure-port=4443 --kubelet-insecure-tls --kubelet-preferred-address-types=InternalIP,ExternalIP,Hostname

Hi @zmicier0k,
Since Kubernetes release v1.22 the metrics-server v0.3.x may no longer be compatible with latest releases. I would suggest installing the latest metrics-server release v0.6.x and at step 5 provide the following arguments when editing the metrics-server Deployment resource:
- --kubelet-insecure-tls - --kubelet-preferred-address-types=Hostname,InternalDNS,InternalIP,ExternalDNS,ExternalIP
Regards,
