Could you add a log

    local cjson = require("cjson.safe"); ngx.log(ngx.EMERG, "AA", cjson.encode(apiserver))

in

apisix/apisix/discovery/kubernetes/informer_factory.lua

Line 48 in 4562875

local response, err = httpc:request({

?

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

我尝试通过api创建一个路由 因为dashboard还没办法创建 命令如下 但是 当我尝试通过apisix访问域名时 发现apisix报错如下 2022/06/03 19:25:53 [error] 3135#3135: *10445111 [lua] init.lua:517: http_access_phase(): failed to set upstream: no valid upstream node: nil, client: 100.100.100.100, server: _, request: "GET /actuator/health HTTP/1.1", host: "teacher-test.xxxx.cn” 官网中没有对kubernetes的自动发现做详细的描述 所以此刻 我不清楚问题出在了哪里 上图中 service_name字段 yace是我k8s中的namespace teacher-app是我的endpoints名称

In the line above this line of code:

apisix/apisix/discovery/kubernetes/informer_factory.lua

Line 48 in 4562875

local response, err = httpc:request({

The new code was added to print what apiserver is.

请回复一下这个问题

This log indicates that APISIX was unable to query valid IP from kubernates based on service_name. From the information you provided it is hard to tell where the problem is.

官网中没有对kubernetes的自动发现做详细的描述 所以此刻 我不清楚问题出在了哪里

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

You can choose to read the source code to understand it.

Or you can try the suggestion above to add log output and let's locate the problem together.

请问一下是否能够提供一个通过api创建自动发现类型为kubernetes的路由的例子

…

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

hi @zhixiongdu027 , can you provide some examples?

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。

[zhixiongdu027]

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 ([email protected])
