使用 python k8s 客户端获取持久卷声明的详细信息

Question

I'm trying to get details of persistentvolumeclaim such as "Used By" which you can get when you run kubectl describe pvc [your-pvc-name] but I'm trying to get that using python k8s client. I'm able to get YAML of the pvc through readNamespacedPersistentVolumeClaim() function but it doesn't contain the "Used By" . How to use python k8s client to get details of a persistentvolumeclaim such as "Used By" .

Answer 1

from kubernetes import client


def get_pod_related_to_pvc(pvc_obj, pv_obj):
 v1 = client.CoreV1Api()
 pod = None
 pod_list = v1.list_namespaced_pod(pvc_obj.metadata.namespace)
 for pod in pod_list.items:
    for volume in pod.spec.volumes:
        if volume.persistent_volume_claim:
            if (volume.persistent_volume_claim.claim_name == pv_obj.spec.claimRef.name):
                return pod

This code seems to work perfectly to list all pods with their respective pvc in a namespace from that we can filter out the pod we want.
