Kubernetes CustomResourceDefinitions

Using Custom Resource Definitions and Custom Resources in Kubernetes

Create a CustomResourceDefintion

See [crd.yaml][] for a CRD. Create it:

kubectl -f crd.yaml

You can check that the new CRD also created a new namespaces API endpoint at /apis/${group}/${version}/namespaces/*/${plural} (in this case: /apis/stable.example.com/v1/namespaces/*/crontabs)

kubectl proxy &
curl http://127.0.0.1:8001/apis/stable.example/v1/namespaces/*/crontabs

{"apiVersion":"stable.example.com/v1","items":[],"kind":"CronTabList","metadata":{"continue":"","resourceVersion":"69668","selfLink":"/apis/stable.example.com/v1/namespaces/*/crontabs"}}
