CoreWeave Upgrade & Migration

Overview

CoreWeave is a GPU-specialized cloud provider running Kubernetes-native infrastructure. Migrations involve upgrading between GPU instance types (A100 to H100), updating CUDA driver versions, and handling Kubernetes API version changes across namespaces. Tracking API versions is critical because CoreWeave's instance type labels and resource quotas change between platform releases, and deploying to a deprecated instance class will cause scheduling failures.

Version Detection

import { KubeConfig, CoreV1Api } from "@kubernetes/client-node";

async function detectCoreWeaveVersion(): Promise<void> {
  const kc = new KubeConfig();
  kc.loadFromDefault();
  const k8sApi = kc.makeApiClient(CoreV1Api);

  // Check current namespace GPU allocations
  const pods = await k8sApi.listNamespacedPod("my-namespace");
  for (const pod of pods.body.items) {
    const gpuClass = pod.spec?.nodeSelector?.["gpu.nvidia.com/class"];
    const cudaVersion = pod.metadata?.labels?.["cuda-version"];
    console.log(`Pod ${pod.metadata?.name}: GPU=${gpuClass}, CUDA=${cudaVersion}`);
  }

  // Detect deprecated instance types
  const deprecated = ["A100_PCIE_40GB", "V100_PCIE_16GB", "RTX_A5000"];
  const activeGpus = pods.body.items
    .map((p) => p.spec?.nodeSelector?.["gpu.nvidia.com/class"])
    .filter(Boolean);
  const stale = activeGpus.filter((g) => deprecated.includes(g!));
  if (stale.length > 0) console.warn(`Deprecated GPU types in use: ${stale.join(", ")}`);
}

Migration Checklist

• Review CoreWeave release notes for deprecated instance types
• Audit all deployments for gpu.nvidia.com/class node selectors
• Verify CUDA version compatibility with target GPU (see matrix below)
