Custom resource

After the CRD is applied, objects of that type (custom resources, CRs) are created. apiVersion is group/version, and kind is the kind from the CRD:

apiVersion: ornek.com/v1
kind: Yedek
metadata:
  name: magaza-gece
  namespace: magaza
spec:
  veritabani: db
  takvim: "0 3 * * *"
  saklamaGun: 14

$ kubectl apply -f yedek.yaml
yedek.ornek.com/magaza-gece created
$ kubectl get yd -n magaza
NAME          AGE
magaza-gece   5s

The default kubectl get output has only NAME and AGE. By adding additionalPrinterColumns to the CRD, important fields are shown in the table:

    - name: v1
      additionalPrinterColumns:
        - name: Veritabani
          type: string
          jsonPath: .spec.veritabani
        - name: Takvim
          type: string
          jsonPath: .spec.takvim

$ kubectl get yd -n magaza
NAME          VERITABANI   TAKVIM      AGE
magaza-gece   db           0 3 * * *   2m
