marchlhw opened a new issue #864:
URL: https://github.com/apache/apisix-ingress-controller/issues/864


   ### Issue description
   
   1. 我在使用apisix ingress 
controller的情况下，只创建apisixupstream对象，发现etcd中没有生产对应的upstream，如下：

   apisix ingress controller输出如下类似的日志：
   2022-02-13T15:16:29+08:00    warn    apisix/upstream.go:70   upstream not 
found      {"name": "apisix_httpbin_80", "url": 
"http://10.115.21.113:9180/apisix/admin/upstreams/f7a2533e";, "cluster": 
"default"}
   2022-02-13T15:16:29+08:00    warn    ingress/controller.go:653       
upstream is not referenced      {"cluster": "name=default; 
base_url=http://10.115.21.113:9180/apisix/admin";, "upstream": 
"apisix_httpbin_80"}

   2. 
如果我删掉apisixupstream对象后，仅创建apisixroute对象，发现etcd中不仅创建对象了upstream，还创建了route，如下：

   3. 
述求：结合我们的实际使用场景，我只想在创建apisixupstream后，控制器调用apisix管理api在etcd中生成相应的upstream，并实时更新，其他的对象比如route、plugin、customer等统一通过dashbord创建，但是按照以上我实际测试出来的情况，满足不了我的诉求，不确定apisix
 ingress controller就是这么设计的，还是有问题
   
   
   
   ### Environment
   
   - your apisix-ingress-controller version (output of 
apisix-ingress-controller version --long):

   - your Kubernetes cluster version (output of kubectl version):

   - if you run apisix-ingress-controller in Bare-metal environment, also show 
your OS version (uname -a):
