##### SUMMARY
<!-- Explain the problem/feature briefly -->
When a kubernetes cluster is spinned up metric API is not available. We will
have to configure metric API manually. Without metric API horizontal pod auto
scale will not work and also kubernetes admin won't able to know the
utilisation each pod and node is accuring.
There are different way to enable metric API but I feel more easy on below
steps.
Step 1 : Check metric API
kubectl top nodes
(it will show metric API not available error)
Step2: Install metric API from kubernetes git
kubectl apply -f
https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml
Step 3: Check metric pod is running
Kubectl -n kube-system get pods
Step 4: Edit metric server deployement and below line
kubectl -n kube-system edit deploy metrics-server
<Add below lines after metric-resolution=15s in containers tag>
command:
- /metrics-server
- --kubelet-insecure-tls
- --kubelet-preferred-address-types=InternalIP
Step 5: Check metric API
kubectl top nodes
##### STEPS TO REPRODUCE
<!--
For bugs, show exactly how to reproduce the problem, using a minimal
test-case. Use Screenshots if accurate.
For new features, show how the feature would be used.
-->
Just bring up a cluster and type kubectl top nodes command will get metric
API unavailable message
##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
If a user bring up a kubernetes cluster they should get maximum componenets
on cluster so that they don't want to go around for each. If any changes on
this can be done please do the needful so it can help users using kubernetes on
cloudstack
