Implementation Reference

• src/tools/kubernetes/deployments.ts:132-155 (handler)

  The actual implementation of the tool, performing the scale operation via Kubernetes API patch.

  export async function scaleDeployment(args: Record<string, unknown>): Promise<string> {
    const api = getAppsV1Api();
    const namespace = (args.namespace as string) || "default";
    const name = args.name as string;
    const replicas = args.replicas as number;
  
    if (!name) throw new Error("Deployment name is required");
    if (replicas === undefined) throw new Error("Replicas count is required");
  
    const patch = { spec: { replicas } };
    await api.patchNamespacedDeployment(
      name,
      namespace,
      patch,
      undefined,
      undefined,
      undefined,
      undefined,
      undefined,
      { headers: { "Content-Type": "application/strategic-merge-patch+json" } }
    );
  
    return `Deployment '${name}' scaled to ${replicas} replicas in namespace '${namespace}'.`;
  }
