# How to use
|
||||
The Kubevela platform out of the box provides supported and complete `StatefulSet` component and `Storage` trait. This example is just provided for education.
|
||||
|
||||
Please check also the online documentation:
|
||||
* [Trait Definition](https://kubevela.io/docs/platform-engineers/traits/customize-trait/)
|
||||
* [Component Definition](https://kubevela.io/docs/platform-engineers/components/custom-component/)
|
||||
|
||||
# Yet another example defining a custom component and custom trait
|
||||
|
||||
1. define a stateful component with StatefulSet as output
