i have linux command to get the resource usage of the pods in particular namespace what is the equivalent python command for it
$ kubectl top pod
NAME CPU(cores) MEMORY(bytes)
nginx-deployment-7fd6966748-57mt5 0m 2Mi
nginx-deployment-7fd6966748-jpbjl 0m 2Mi
nginx-deployment-7fd6966748-snrx4 0m 2MiThere is no single command.
Kubernetes metrics are exposed on metrics.k8s.io. You will have to write program to query the API and get results.
For example for nodes.
This API is made available under the /apis/metrics.k8s.io/ endpoint
kubectl get --raw "/apis/metrics.k8s.io/v1beta1/nodes" | jq for node metrics
Thanks for the input the following command worked fine
>>> from kubernetes import client, config
>>>
>>> config.load_kube_config()
>>> api = client.CustomObjectsApi()
>>> resource = api.list_namespaced_custom_object(group="metrics.k8s.io",version="v1beta1", namespace="default", plural="pods")
>>> for pod in resource["items"]:
... print(pod['containers'], "\n")
...You can run kubectl commands with python as well.
from subprocess import call
call('kubectl describe pod pod_name_here -n default', shell=True)So you can filter anything with the Python Kubernetes library and also use kubectl commands to ease your work.
