我正在尝试使用 kubernetes 执行器设置气流。我已经克隆了气流 1.10.6 并正在构建 docker 镜像，然后使用 kube 部署它。Pod 正在运行，服务气流也开始运行。网络服务器工作正常。但是当我检查调度程序的日志时，我收到以下错误。

ERROR - Error while health checking kube watcher process. Process died for unknown reasons
INFO - Event: and now my watch begins starting at resource_version: 0
ERROR - Unknown error in KubernetesJobWatcher. Failing

我正在编写一个java代码,我需要将JSONObject转换为JsonElement.Is有什么方法可以将JSONObject(org.json)转换为JsonElement(com.google.gson)？

我使用以下代码在Elasticsearch上创建客户端:

Settings settings = Settings.builder()
    .put("cluster.name", "myClusterName")
    .build();
TransportClient client = new PreBuiltTransportClient(settings)
    .addTransportAddress(newInetSocketTransportAddress(InetAddress.getByName("127.0.0.1"), 9300));

我收到这些错误:

我正在尝试将与 jupyterhub 一起运行的 jupyterlab 集成到 iframe 中。我在配置文件中进行了所有必需的更改。在 jupyter_notebook_config.py 中，我进行了以下更改。

c.NotebookApp.tornado_settings = {'headers': {
    'Access-Control-Allow-Origin': '*',
    'Content-Security-Policy': 'frame-ancestors http://localhost:9005'
  }}

在 jupyterhub_config.py 中我添加了以下内容

c.JupyterHub.tornado_settings = {'headers': {
    'Access-Control-Allow-Origin': '*',
    'Content-Security-Policy': 'frame-ancestors http://localhost:9005'
  }}

但是，当我尝试在 iframe 中打开http://localhost:8002/user/admin/lab URL 时，出现以下错误

Refused to display 'http://localhost:8002/user/admin/lab' in a frame because an ancestor violates the following Content Security Policy directive: "frame-ancestors 'self'".

如果我遗漏了什么或者我的配置有问题，有人可以告诉我吗？
