# LWS Based PD Deploy
## 0. Prerequisites
1. k8s >=1.26
2. lws installed on k8s.
## 1. Image Preparation
`lmsysorg/sglang:deepep`
## 2. Deployment Manifest Files
***Notice: We will package all deployment files into Helm Chart format in the near future. Interested community members can contact us to contribute***
### Prefill
Prefill manifest file [prefill.yaml](lws-examples/p.yaml)
*Note: The NodeSelector section, model location section, and taint toleration section can be adjusted according to your actual deployment environment*

Execute separately:
```bash
kubectl apply -f p.yaml
kubectl apply -f d.yaml
```
At this point, we have completed the deployment of the 1P1D SGlang engine part.
To allow our users to directly experience the model API, we still need a load balancer to handle sequential calls between prefill and decode. Different companies implement LBs differently, and the community will also officially release a new LB component written in Rust in the near future.
Currently, we use a static K8S service + minilb approach to implement model API calls.
### Creating Service for Prefill and Decode
#### Create prefill k8s service
[p-svc.yaml](lws-examples/p-svc.yaml)
```yaml
apiVersion: v1
kind: Service
metadata:
name: deepseekr10528-prefill-main
spec:
selector:
leaderworkerset.sigs.k8s.io/name: deepseekr10528-prefill-main
role: leader
ports:
- protocol: TCP
port: 30000
targetPort: 30000
```
Execute `kubectl apply -f p-svc.yaml`
#### Create decode k8s service
[d-svc.yaml](lws-examples/d-svc.yaml)
```yaml
apiVersion: v1
kind: Service
metadata:
name: deepseekr10528-decode-main
spec:
selector:
leaderworkerset.sigs.k8s.io/name: deepseekr10528-decode-main
role: leader
ports:
- protocol: TCP
port: 30000
targetPort: 30000
```
Execute `kubectl apply -f d-svc.yaml`
#### Deploy minilb and lb service
[lb.yaml](lws-examples/lb.yaml)
```yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: deepseekr10528-lb-main
labels:
app: deepseekr10528-lb
spec:
replicas: 1
selector:
matchLabels:
app: deepseekr10528-lb
template:

labels:
app: deepseekr10528-lb
spec:
nodeSelector:
pd: "yes"
tolerations:
- key: pd
operator: Exists
- key: node-role
operator: Exists
containers:
- name: sgl-minilb

command:
- python
- -m

- --prefill

- --decode
- http://deepseekr10528-decode-main:30000
- --host
- 0.0.0.0
- --port
- "8000"
ports:
- containerPort: 8000
---
apiVersion: v1
kind: Service
metadata:
name: deepseekr10528-lb-service
spec:
type: NodePort
selector:
app: deepseekr10528-lb
ports:
- protocol: TCP
port: 8000 # Service Port（In-Cluster）
targetPort: 8000 # Exposed Container
nodePort: 30800
```
Execute `kubectl apply -f lb.yaml`
After waiting for all model deployments to succeed, you will get the following output:
```bash
[root@ecs-001]# kubectl get po

```
At this point, select a nodePort:30800 to access:
```bash

## FAQ
1. The current deployment startup parameters may not be fully compatible with all RDMA scenarios. Different RDMA NCCL-related environment configurations may be needed in different network environments.
2. Some preset, optimized configurations for EPLB are not used here. You can adjust them according to [6017](https://github.com/sgl-project/sglang/issues/6017) as needed.
