Marker (GPU service)

Goal

• Run marker locally on the NVIDIA GPU and expose its API in Kubernetes.
• Keep the pod single-replica and single-worker so it fits in 4 GB VRAM.

Resources

File	Description
Dockerfile	CUDA-based image built from pytorch/pytorch and marker-pdf.
deployment.yaml	Single GPU-backed Deployment for marker_server.
service.yaml	ClusterIP service on port 8001.

How to use

1. Build and push the image:

   docker build -t <your-registry>/marker:latest ~/services/apps/marker
   docker push <your-registry>/marker:latest
   

2. Update deployment.yaml with that image tag.
3. Apply the manifests:

   kubectl apply -f ~/services/apps/marker/deployment.yaml
   kubectl apply -f ~/services/apps/marker/service.yaml
   

4. Check the pod is using the GPU:

   kubectl logs deploy/marker
   kubectl exec -it deploy/marker -- nvidia-smi
   

Notes

• No PVC is used; the container only needs ephemeral storage.
• Keep replicas: 1 and avoid concurrent jobs on this 4 GB card.
• If the server needs an explicit bind address in your build, change the container args to 0.0.0.0:8001 equivalent for marker_server.
