# kubectl-creyaml

Generate Custom Resource Example Yaml (CREYaml) from Custom Resource Definition

kubectl-creyaml helps you to create an example Custom Reource(CR) definition for any Custom Resource Definition(CRD) installed in a Kubernetes cluster.

## Example

For a CRD defined as, 

```

apiVersion: apiextensions.k8s.io/v1

kind: CustomResourceDefinition

metadata:

  name: crontabs.stable.example.com

spec:

  group: stable.example.com

  versions:

    - name: v1

      served: true

      storage: true

      schema:

        openAPIV3Schema:

          type: object

          properties:

            spec:

              type: object

              properties:

                cronSpec:

                  type: string

                image:

                  type: string

                replicas:

                  type: integer

  scope: Namespaced

  names:

    plural: crontabs

    singular: crontab

    kind: CronTab

    shortNames:

    - ct

```

```kubectl creyaml crontabs.stable.example.com``` will generate the below

```

apiVersion: stable.example.com/v1

kind: CronTab

metadata:

  name: ""

  annotations: {}

spec:

  cronSpec: string

  image: string

  replicas: integer

```

Notice how the mentioned type of each property in under spec.
