[GitHub] [apisix] liangyawang opened a new issue, #7185: bug: Independent external APIs cannot be automatically discovered by linking APIs servers
liangyawang opened a new issue, #7185:
URL: https://github.com/apache/apisix/issues/7185
### Current Behavior
I'm on the official website at: https://apisix.apache.org/docs/apisix/discovery/kubernetes Apifix is configured for automatic discovery based on kubernetes in the boot of, but errors are always reported in the process, as shown in the following figure
In the following two figures, one is my configuration and the other is my error message. My apifix version is 2.14.1
### Expected Behavior
According to the document on the official website, do automatic discovery directly through kubernetes rather than through Nacos or other registration centers
### Error Logs
### Steps to Reproduce
1. 通过裸机部署apisix
2. 在配置文件中按照https://apisix.apache.org/docs/apisix/discovery/kubernetes配置
3. 重启apisix 观察error.log
### Environment
- APISIX version (run `apisix version`):
- Operating system (run `uname -a`):
- OpenResty / Nginx version (run `openresty -V` or `nginx -V`):
- etcd version, if relevant (run `curl http://127.0.0.1:9090/v1/server_info`):
- APISIX Dashboard version, if relevant:
- Plugin runner version, for issues related to plugin runners:
- LuaRocks version, for installation issues (run `luarocks --version`):

Could you add a log
```
local cjson = require("cjson.safe"); ngx.log(ngx.EMERG, "AA", cjson.encode(apiserver))
```
in https://github.com/apache/apisix/blob/4562875348fdaab3cb05e6df8aecf0604fa6e157/apisix/discovery/kubernetes/informer_factory.lua#L48?

Dear team member
Do you have any examples about the configuration of automatic discovery by APIs through kubernetes and the creation of routes with kubernetes as the type of automatic discovery through APIs? If yes, please send me examples for other types of automatic discovery in the official website, except kubernetes. I think I may have used them incorrectly, so please give me two examples to try. Thank you very much

您好 请问您会讲中文吗 如果会的话 我向您提问一下 这行代码加在lua文件的什么位置？
还有个问题，当我把配置中的token_file改位token时它不再出现报错 但是我也不能确定它是否获取到了对应的endpoints

I'm sorry, I've done several scene simulations locally and can't reproduce the situation in the picture.
Maybe the problem is related to the cluster configuration,
Is it convenient for me to communicate quickly through Im (wechat ,qq, mail) to solve this problem?
You can send your qq,wechart to my mail (root@libssl.com)

I didn't find an article describing this in detail either.

抱歉抱歉，我现在才看到此信息。
我将在今晚尝试复现和修复此问题，
根据报错信息显示，我初步怀疑跟
apiserver 的初始化有关。
