CoreWeave Deploy Integration

Overview

Deploy GPU-accelerated inference services on CoreWeave Kubernetes (CKS). This skill covers containerizing inference workloads with NVIDIA CUDA base images, configuring GPU resource limits and node affinity for A100/H100 scheduling, setting up health checks that validate GPU availability and model loading, and executing rolling updates that respect GPU node draining. CoreWeave's scheduler requires explicit GPU resource requests to place pods on the correct hardware tier.

Docker Configuration

Prerequisites

• A reviewed image digest in an approved registry and a namespace-scoped image pull secret.
• A production deployment manifest with resource limits, health checks, SLO, and rollback revision.
• Approval for the target namespace, GPU capacity, and service exposure.

Instructions

1. Build and scan the image, then deploy the immutable digest to staging first.
2. Verify readiness, health, GPU allocation, and baseline request behavior before promotion.
3. Use a controlled rolling update with a timeout and named observer.
4. Roll back immediately if readiness, error rate, latency, or security verification fails.

Environment Variables

export COREWEAVE_API_KEY="cw_xxxxxxxxxxxx"
export COREWEAVE_NAMESPACE="tenant-my-org"
export MODEL_NAME="meta-llama/Llama-3.1-8B-Instruct"
export GPU_TYPE="A100_PCIE_80GB"
export GPU_COUNT="1"
export LOG_LEVEL="info"
export PORT="8080"

Health Check Endpoint

import express from 'express';
import { execSync } from 'child_process';

const app = express();

app.get('/health', async (req, res) => {
  try {
    const gpuInfo = execSync('nvidia-smi --query-gpu=name,memory.used --format=csv,noheader').toString().trim();
    const modelLoaded = globalThis.modelReady === true;
    if (!modelLoaded) throw new Error('Model not loaded');
    res.json({ status: 'healthy', gpu: gpuInfo, model: process.env.MODEL_NAME, timestamp: new Date().toISOString() });
  } catch (error) {
    res.status(503).json({ status: 'unhealthy', error: (error as Error).message });
  }
});

Deployment Steps

Step 1: Build

docker build -t registry.coreweave.com/my-org/inference-svc:latest .
docker push registry.coreweave.com/my-org/inference-svc:latest

Step 2: Run

# k8s/deployment.yaml
resources:
  limits:
    nvidia.com/gpu: 1
    cpu: "4"
    memory: "48Gi"
nodeSelector:
  gpu.nvidia.com/class: A100_PCIE_80GB

kubectl apply -f k8s/deployment.yaml -n tenant-my-org

Step 3: Verify

kubectl get pods -n tenant-my-org -l app=inference-svc
curl -s http://inference-svc.tenant-my-org.svc.cluster.local:8080/health | jq .

Step 4: Rolling Update

kubectl set image deployment/inference-svc \
  inference=registry.coreweave.com/my-org/inference-svc:v2 \
  -n tenant-my-org
kubectl rollout status deployment/inference-svc -n tenant-my-org --timeout=600s

Error Handling

Output

• A versioned, health-checked GPU deployment with declared capacity and ownership.
• A rollout receipt containing image digest, readiness result, and redacted event evidence.
• A known rollback command and threshold for using it.

Examples

Deploy an immutable staging image and wait for the rollout before sending traffic:

kubectl -n tenant-staging set image deployment/inference-svc \
  inference=registry.coreweave.com/my-org/inference-svc@sha256:REVIEWED_DIGEST
kubectl -n tenant-staging rollout status deployment/inference-svc --timeout=10m

If the rollout fails, use kubectl rollout undo for the same deployment and record the redacted events. Do not retag latest, bypass health checks, or substitute plaintext credentials.
