   By following @kezhenxu94 ,  oap and java app are mounted into e2e container. But, nginx could,t connect to upstream only when Lua agent registering as the following configuration:
   
   ```conf
   http {
       lua_package_path "/usr/share/skywalking-nginx-lua/lib/skywalking/?.lua;;";
       # Buffer represents the register inform and the queue of the finished segment
       lua_shared_dict tracing_buffer 100m;
   
       # Init is the timer setter and keeper
       # Setup an infinite loop timer to do register and trace report.
       init_worker_by_lua_block {
           local metadata_buffer = ngx.shared.tracing_buffer
   
           metadata_buffer:set('serviceName', 'User_Service_Name')
           -- Instance means the number of Nginx deloyment, does not mean the worker instances
           metadata_buffer:set('serviceInstanceName', 'User_Service_Instance_Name')
   
           require("client"):startBackendTimer("http://upstream:12800")
       }
       log_format sw_trace escape=json "$uri $request_body";
   
       server {
           listen 8080;
   
           location /e2e/users {
   
               rewrite_by_lua_block {
                   require("tracer"):startBackendTimer()
               }
   
               proxy_pass http://upstream:9090/e2e/users;
   
               body_filter_by_lua_block {
                   require("tracer"):finish()
               }
   
               log_by_lua_block {
                   require("tracer"):prepareForReport()
               }
           }
   
           location /health-check {
   
               rewrite_by_lua_block {
                   require("tracer"):startBackendTimer()
               }
   
               proxy_pass http://upstream:9090/e2e/health-check;
   
               body_filter_by_lua_block {
                   require("tracer"):finish()
               }
   
               log_by_lua_block {
                   require("tracer"):prepareForReport()
               }
           }
       }
   }
   ```
   
   BTW, according to log, `upstream:9090/e2e/users` connected successfully.
