构建了jupyterhub的docker，要运行起来，但报以下错误：
nodejs run[28]: ../src/node_platform.cc:58:std::unique_ptr<long unsigned int> node::BackgroundTaskRunner::DelayedTaskScheduler::Start(): Assertion `(0) == (uv_thread_create(t.get(), start_thread, this))' failed.

查了下可能是资源问题，运行时加 --privileged 解决。
sudo docker run --privileged ...
