Managing custom objects

After you create objects, you can manage your custom resources.

Prerequisites

• Create a custom resource definition (CRD).

• Create an object from a CRD.

Procedure

1. To get information on a specific kind of custom resource, enter:

   oc get <kind>

   For example:

   oc get crontab
   
   NAME                 KIND
   my-new-cron-object   CronTab.v1.stable.example.com

   Note that resource names are not case-sensitive, and you can use either the singular or plural forms defined in the CRD, as well as any short name. For example:

   oc get crontabs
   oc get crontab
   oc get ct

2. You can also view the raw YAML data for a custom resource:

   oc get <kind> -o yaml

   oc get ct -o yaml
   
   apiVersion: v1
   items:
   - apiVersion: stable.example.com/v1
     kind: CronTab
     metadata:
       clusterName: ""
       creationTimestamp: 2017-05-31T12:56:35Z
       deletionGracePeriodSeconds: null
       deletionTimestamp: null
       name: my-new-cron-object
       namespace: default
       resourceVersion: "285"
       selfLink: /apis/stable.example.com/v1/namespaces/default/crontabs/my-new-cron-object
       uid: 9423255b-4600-11e7-af6a-28d2447dc82b
     spec:
       cronSpec: '* * * * /5' (1)
       image: my-awesome-cron-image (1)

   1. Custom data from the YAML that you used to create the object displays.
