This issue can be seen every time when “docker pull”

My docker image size is hundreds of MB or several GB. At last, I found , in the Nginx templates, the proxy_max_temp_file_size is not set and its default value will cause above issue. so I made modification like this:

proxy_max_temp_file_size 0;

Then the issue was gone.
