Built-in APIs

kcp includes some, but not all, of the APIs you are likely familiar with from Kubernetes:

(core) v1

  • Namespaces
  • ConfigMaps
  • Secrets
  • Events
  • LimitRanges
  • ResourceQuotas
  • ServiceAccounts

admissionregistration.k8s.io/v1

  • MutatingWebhookConfigurations
  • ValidatingWebhookConfigurations

apiextensions.k8s.io/v1

  • CustomResourceDefinitions

authentication.k8s.io/v1

  • TokenReviews

authorization.k8s.io/v1

  • LocalSubjectAccessReviews
  • SelfSubjectAccessReviews
  • SelfSubjectRulesReviews
  • SubjectAccessReviews

certificates.k8s.io/v1

  • CertificateSigningRequests

coordination.k8s.io/v1

  • Leases

events.k8s.io/v1

  • Events

flowcontrol.apiserver.k8s.io/v1beta1 (temporarily removed)

  • FlowSchemas
  • PriorityLevelConfigurations

rbac.authorization.k8s.io/v1

  • ClusterRoleBindings
  • ClusterRoles
  • RoleBindings
  • Roles

Notably, workload-related APIs (Pods, ReplicaSets, Deployments, Jobs, CronJobs, StatefulSets), cluster-related APIs ( Nodes), storage-related APIs (PersistentVolumes, PersistentVolumeClaims) are all missing - kcp does not include these, and it instead relies on workload clusters to provide this functionality.
