What Should I Do If the Host Cannot Be Found When Files Need to Be Uploaded to OBS During the Access to the CCE Service from a Public Network?

When a Service deployed on CCE attempts to upload files to OBS after receiving an access request from an offline machine, an error message is displayed, indicating that the host cannot be found. The following figure shows the error message.

Fault Locating

After receiving the HTTP request, the Service transfers files to OBS through the proxy.

If too many files are transferred, a large number of resources are consumed. Currently, the proxy is assigned 128 MiB of memory. According to pressure test results, resource consumption is large, resulting in request failure.

The test results show that all traffic passes through the proxy. Therefore, if the service volume is large, more resources need to be allocated.

Solution

  1. File transfer involves a large number of packet copies, which occupies a large amount of memory. In this case, increase the proxy memory based on the actual scenario and then try to access the Service and upload files again.
  2. Additionally, remove the Service from the mesh because the proxy only forwards packets and does not perform any other operations. If requests pass through the ingress gateway, the grayscale release function of the Service is not affected.
