Implementation Reference

• src/tools/kubernetes/logs.ts:3-45 (handler)

  The actual implementation of the tool that interacts with the Kubernetes API to fetch pod logs.

  export async function getPodLogs(args: Record<string, unknown>): Promise<string> {
    const api = getCoreV1Api();
    const namespace = (args.namespace as string) || "default";
    const name = args.name as string;
    const container = args.container as string | undefined;
    const tail = (args.tail as number) || 100;
    const since = args.since as string | undefined;
    const previous = (args.previous as boolean) || false;
  
    if (!name) throw new Error("Pod name is required");
  
    let sinceSeconds: number | undefined;
    if (since) {
      const match = since.match(/^(\d+)([smhd])$/);
      if (match) {
        const value = parseInt(match[1]);
        const unit = match[2];
        const multipliers: Record<string, number> = { s: 1, m: 60, h: 3600, d: 86400 };
        sinceSeconds = value * (multipliers[unit] || 1);
      }
    }
  
    const response = await api.readNamespacedPodLog(
      name,
      namespace,
      container,
      undefined,
      undefined,
      undefined,
      undefined,
      previous,
      sinceSeconds,
      tail
    );
  
    const logs = response.body;
    if (!logs || logs.trim().length === 0) {
      return `No logs found for pod '${name}'${container ? ` container '${container}'` : ""} in namespace '${namespace}'.`;
    }
  
    const header = `Logs for pod '${name}'${container ? ` (container: ${container})` : ""} in '${namespace}' (last ${tail} lines):`;
    return `${header}\n\n${logs}`;
  }
