 1. The example of the official StatefulSet website is a composite component composed of two objects `StatefulSet` and `Service`. According to KubeVela [Rules for customize component](https://kubevela.io/docs/platform-engineers/components/custom-component), in composite components, one of the resources such (StatefulSet in our example) need to be represented by the `template.output` field as a core workload, and other auxiliary objects are represented by `template.outputs`, so we make some adjustments and all the automatically generated output and outputs are switched.
 2. Then we fill in the apiVersion and kind data of the core workload into the part marked as `<change me>`
