$ operator-sdk new app-operator --api-version=app.example.com/v1alpha1 --kind=App
$ cd  app-operator

$ cat deploy/crd.yaml
apiVersion: apiextensions.k8s.io/v1beta1
kind: CustomResourceDefinition
metadata:
  name: apps.app.example.com
spec:
  group: app.example.com
  names:
    kind: App
    listKind: AppList
    plural: apps
    singular: app
  scope: Namespaced
  version: v1alpha1

$ cat deploy/operator.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: app-operator
spec:

    spec:
      containers:

          image: quay.io/fanminshi/example:app-operator
          command:

$ kubectl create -f deploy/rbac.yaml
role "app-operator" created
$ kubectl create -f deploy/crd.yaml
customresourcedefinition "apps.app.example.com" created

$ operator-sdk build quay.io/fanminshi/example:app-operator

I know the template name doesn't actually matter but this should be crdTmplName.

@hasbro17 yeah, the name doens't matter. just for formality i guess. good catch on this one.
