[GitHub] [apisix] unsw-luopan opened a new issue, #8774: help request: 502 Bad Gateway

unsw-luopan opened a new issue, #8774:
URL: https://github.com/apache/apisix/issues/8774

   ### Description
   
   I run apisix, nacos and a flask service in the same docker network with different containers. Follow this tutorial "https://apisix.apache.org/zh/blog/2022/02/21/nacos-api-gateway/" to build an example. Then I curl apisix from my host computer and get 502 result. What's wrong with my configuration?
   
   apisix conf:
   ......
   discovery:
     nacos:
       host:
         - "http://192.168.32.2:8848"
       prefix: "/nacos/v1/"
   
   Apisix route registry command:
   curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -i -d '
   {
       "uri": "/nacos/*",
       "upstream": {
           "service_name": "algorithm-service",
           "type": "roundrobin",
           "discovery_type": "nacos"
       }
   }'
   
   curl command:
   curl -i http://127.0.0.1:9080/nacos/
   
   apisix error log:
   2023/02/01 08:38:03 [error] 47#47: *2642 connect() failed (111: Connection refused) while connecting to upstream, client: 192.168.32.1, server: _, request: "GET /nacos/ HTTP/1.1", upstream: "http://0.0.0.0:8085/nacos/", host: "127.0.0.1:9080"
   
   apisix access log:
   192.168.32.1 - - [01/Feb/2023:08:38:03 +0000] 127.0.0.1:9080 "GET /nacos/ HTTP/1.1" 502 229 0.001 "-" "curl/7.68.0" 0.0.0.0:8085 502 0.001 "http://127.0.0.1:9080"
   
   
   ### Environment

   Nacos version: 2.2.0

   `0.0.0.0` is not reachable. How APISIX send requests to it?
