Distributed Inference using KubeRay Job

Note: While it definitely works with RayCluster, using RayJob is much easier.

1. Container Image seedjeffwan/vllm-openai:v0.5.2-distributed

FROM vllm/vllm-openai:v0.5.2
RUN apt update && apt install -y wget # important for future healthcheck
RUN pip3 install ray[default] # important for future healthcheck

Setups to try workspace operator

1. Make sure you have ray-system namespace. if not, kubectl create ns ray-system
2. kubectl create -f ray.io_workspaces.yaml
3. kubectl apply -f workspace-operator.yaml
4. Create a jupyter notebook. kubectl apply -f ray.io_v1alpha1_workspace.yaml
5. Use the nodeport or port-forward the service. Then open browser nodeip:nodeport/kuberay/workspace.

Note: operator image and jupyter image can be used directly. I upload to my personal dockerhub. I will try to finish OSS process soon.
