Inspecting Custom Resources

You can inspect Custom Resource (CR) objects that exist in your cluster using the CLI.

Prerequisites

• A CR object exists in a namespace to which you have access.

Procedure

1. To get information on a specific Kind of a CR, run:

   $ oc get <kind>

   For example:

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

   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 CR:

   $ 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.
