这是一个跨域请求错误。CORS（跨源资源共享）是一种安全机制，用于限制网页或应用程序在一个域中访问另一个域的资源。在你提供的请求中，浏览器阻止访问'https://10.10.16.117/boot/streamAi/snap'，因为它的响应中缺少'Access-Control-Allow-Origin'头部，该头部指示浏览器允许来自特定源的请求。

要解决这个问题，你需要在服务器端配置响应头，添加'Access-Control-Allow-Origin'头部，并设置为允许请求的来源。例如，如果你想允许所有来源的请求，可以将其设置为'*'。如果你只想允许特定来源的请求，可以将其设置为该来源的URL。

在这种情况下，你需要在服务器上进行配置更改，以确保响应中包含正确的'CORS'头部。如果你没有服务器控制权，则需要联系API提供商或网站管理员来解决此问题。他们应该能够帮助你配置正确的CORS头部以允许跨域请求。

how to fix Config not found: /etc/kubernetes/admin.conf

The error message "Config not found: /etc/kubernetes/admin.conf" usually indicates that the Kubernetes configuration file is not present in the path mentioned. Here are the steps to fix this issue:

1. Check if the Kubernetes configuration file exists in the specified path. You can do this by running the following command:

   ls -l /etc/kubernetes/admin.conf

If the file does not exist, you can try to locate it by running the following command:

   sudo find / -name admin.conf

This will search for the file in all directories.

2. If you have located the configuration file, copy it to the `/etc/kubernetes/` directory using the following command:

   sudo cp <path-to-admin.conf> /etc/kubernetes/admin.conf

Replace `<path-to-admin.conf>` with the actual path to the configuration file.

3. If the configuration file does not exist, you can generate it using the `kubeadm` tool. Run the following command to generate the configuration file:

   sudo kubeadm init phase kubeconfig admin --kubeconfig-dir=/etc/kubernetes/

This will generate the configuration file and place it in the `/etc/kubernetes/` directory.

4. Once the configuration file is in place, you can try running the Kubernetes command again. For example:

   kubectl get nodes

This should now work.

I hope this helps! Let me know if you have any further questions.
