Which API Group in k8s

Question

How do I determine which apiGroup any given resource belongs in?

kind: Role
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
  namespace: default
  name: thing
rules:
- apiGroups: ["<wtf goes here>"]
  resources: ["deployments"]
  verbs: ["get", "list"]
  resourceNames: []

Answer 1

要获取 Kubernetes 集群支持的 API 资源：

 kubectl api-resources -o wide

example:
NAME                              SHORTNAMES   APIGROUP                       NAMESPACED   KIND                             VERBS
deployments                       deploy       apps                           true         Deployment                   [create delete deletecollection get list patch update watch]
deployments                       deploy       extensions                     true         Deployment                   [create delete deletecollection get list patch update watch]

要获取 Kubernetes 集群支持的 API 版本：

kubectl api-versions

您可以验证 fe 部署：

kubectl explain deploy 

KIND:     Deployment
VERSION:  extensions/v1beta1

DESCRIPTION:
     DEPRECATED - This group version of Deployment is deprecated by
     apps/v1beta2/Deployment.

此外，您可以使用 api-version 进行调查：

kubectl explain deploy --api-version apps/v1

很快你就在你的 apiGroups 中指定了一个：

apiGroups: ["extensions", "apps"]

您还可以通过 在kube-apiserver 中传递选项来使用（例如测试它是否适用于下一个1.16 版本）为您的集群配置这些设置。--runtime-config

其他资源：

• api资源：
• Kubernetes 弃用政策

• 特定版本的其他值得注意的功能更新，请遵循 如下：

  Continued deprecation of extensions/v1beta1, apps/v1beta1, and apps/v1beta2 APIs; these extensions will be retired in 1.16!

在更高的 k8s 版本中，apigroup已弃用，并且该命令kubectl api-resources -o wide将apiversion改为显示，它是以下命令的组合apigroup/version

Answer 3

kubectl api-resources -o wide 提供系统支持的 API 资源。

kubectl api-resources -o wide | grep -i deployment 将提供相关信息

apps是部署资源的 apiGroup

DaemonSet、Deployment、StatefulSet 和 ReplicaSet：在 v1.16 中将不再从 extensions/v1beta1、apps/v1beta1 或 apps/v1beta2 提供服务。迁移到自 v1.9 起可用的 apps/v1 API。可以通过 apps/v1 API 检索/更新现有的持久数据。/api-deprecations-in-1-16
