Implementation Reference

• src/tools/docker/containers.ts:64-87 (handler)

  The containerLogs function retrieves logs from a Docker container using the Docker SDK.

  export async function containerLogs(args: Record<string, unknown>): Promise<string> {
    const docker = getDockerClient();
    const id = args.id as string || args.name as string;
    if (!id) throw new Error("Container ID or name is required");
  
    const tail = (args.tail as number) || 100;
    const since = args.since as number | undefined;
  
    const container = docker.getContainer(id);
    const logs = await container.logs({
      stdout: true,
      stderr: true,
      tail,
      since,
      timestamps: true,
    });
  
    const logStr = typeof logs === "string" ? logs : logs.toString("utf-8");
    if (!logStr.trim()) {
      return `No logs found for container '${id}'.`;
    }
  
    return `Logs for container '${id}' (last ${tail} lines):\n\n${logStr}`;
  }
