2. 各api_group包含的資源類型
這裏舉例的api_group爲核心API組(’ '）以及 apps組下的資源類型
2.1 核心API組(’ ')下的資源類型
# kubectl api-resources --api-group='' -o wide

2.2 apps組下的資源類型
# kubectl api-resources --api-group='apps' -o wide

replicasets rs apps true ReplicaSet [create delete deletecollection get list patch update watch]
statefulsets sts apps true StatefulSet [create delete deletecollection get list patch update watch]
3. 同一個apigroup可能存在多個版本，到底用那個呢
我們可以選擇當前Kubernetes版本（例如1.16.x）推薦的版本 ：preferredVersion，例如
# kubectl get --raw "/apis" |python -mjson.tool
# 選擇個apigroup中的preferredVersion
