一、资源清单结构查询 Kubernetes 集群的 API Server控制中心当前支持哪些 API 组和版本kubectl api-versions[rootk8s-master01 ~]# kubectl api-versions #格式为组/版本 admissionregistration.k8s.io/v1 apiextensions.k8s.io/v1 apiregistration.k8s.io/v1 apps/v1 authentication.k8s.io/v1 authorization.k8s.io/v1 autoscaling/v1 autoscaling/v2 batch/v1 certificates.k8s.io/v1 coordination.k8s.io/v1 crd.projectcalico.org/v1 discovery.k8s.io/v1 events.k8s.io/v1 flowcontrol.apiserver.k8s.io/v1 flowcontrol.apiserver.k8s.io/v1beta3 networking.k8s.io/v1 node.k8s.io/v1 policy/v1 rbac.authorization.k8s.io/v1 scheduling.k8s.io/v1 storage.k8s.io/v1 v1 #这个组是核心组通过kubectl explain 资源类别就可以显示出类别和版本以及该pod的所有参数[rootk8s-master01 ~]# kubectl explain pod KIND: Pod #类别是pod VERSION: v1 #版本 DESCRIPTION: Pod is a collection of containers that can run on a host. This resource is created by clients and scheduled onto hosts. FIELDS: apiVersion string APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources kind string Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase.

More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata ObjectMeta is metadata that all persisted resources must have, which includes all objects users must create. FIELDS: annotations map[string]string Annotations is an unstructured key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata. They are not queryable and should be preserved when modifying objects. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/annotations creationTimestamp string
