| Demo: Setup a DPVS Virtual Service | ||
| ------ | ||
|
|
||
| > This is a demo to setup a miminal fullnat virtual service with dpvs-agent API. Not all supported APIs are involved. We haven't document the dpvs-agent API yet. Refer to [dpvs-agent openapi definition](./dpvs-agent-api.yaml) for a full view of supported API. | ||
| The demo shows how to setup the service from scratch with dpvs-agent API. | ||

| ``` | ||
|
|
||
| Finally, deploy a http service on backend server `192.168.88.30:80`, and make a request to virtual service `192.168.88.100:80` from another server in this network. Hopefully, you may get a success response. |
