CRD YAML

A CRD's name must have the form <plural>.<group>. names gives the type's names, scope the namespace scope, and versions the served API versions and their validation definitions:

apiVersion: apiextensions.k8s.io/v1
kind: CustomResourceDefinition
metadata:
  name: yedekler.ornek.com
spec:
  group: ornek.com
  scope: Namespaced
  names:
    plural: yedekler
    singular: yedek
    kind: Yedek
    shortNames: [yd]
  versions:
    - name: v1
      served: true
      storage: true
      schema:
        openAPIV3Schema:
          type: object
          properties:
            spec:
              type: object
              properties:
                veritabani: {type: string}
                takvim: {type: string}
                saklamaGun: {type: integer}

storage: true shows which version is written to etcd; it must be on exactly one version.

scope: Namespaced binds the type to namespaces (most application resources); Cluster uses a single cluster-wide name space (e.g. a platform setting). names determines which names kubectl recognizes:

names:
  plural: yedekler      # kubectl get yedekler, URL path
  singular: yedek       # kubectl get yedek
  kind: Yedek           # kind in YAML
  shortNames: [yd]      # kubectl get yd
  categories: [all]     # appears in kubectl get all
