Kubernetes python eviction api 抱怨'Name parameter required.'

Question

我试图创建一个python脚本来根据某些条件驱逐节点，但我在获取create_namespaced_pod_viction时遇到了问题举止得体。从api文档中可以看出，我的语法看起来非常正确。感谢您的帮助。我还将提到kubernetes集群在AWS EKS 上是1.10

for i in pods.items:
print("Deleting pod: ", i.metadata.name, i.metadata.namespace, node)
body = kubernetes.client.V1beta1Eviction()
api_response = v1.create_namespaced_pod_eviction(i.metadata.name, i.metadata.namespace, body, dry_run='All', include_uninitialized='True', pretty='True')

这是输出：

('Deleting pod: ', 'ambassador-5d86576878-4kv6w', 'istio-system', 'ip-10-72-20-161.ec2.internal')

对于那些偶然发现这一点的人，我可以通过以下操作来实现这一点：

podName = 'insert-name-of-pod'
podNamespace = 'insert-namespace-of-pod'
body = client.V1beta1Eviction(metadata=client.V1ObjectMeta(name=podName, namespace=podNamespace))
api_response = v1.create_namespaced_pod_eviction(name=podName, namespace=podNamespace, body=body)
