[GitHub] [apisix] sheng-jie opened a new issue, #8220: docs: What does it mean If the kubernetes service discovery runs inside a pod?
sheng-jie opened a new issue, #8220:
URL: https://github.com/apache/apisix/issues/8220
### Current State
In this article：[Discovery-Kubernetes](https://apisix.apache.org/docs/apisix/2.15/discovery/kubernetes/)
The description in italics below is a bit confusing. What does it mean If the kubernetes service discovery runs inside/outside a pod?
_If the kubernetes service discovery runs inside a pod_, you can use minimal configuration:
```
discovery:
kubernetes: { }
```
_If the kubernetes service discovery runs outside a pod_, you need to create or select a specified [ServiceAccount](https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/), then get its token value, and use following configuration:
```
discovery:
kubernetes:
service:
schema: https
host: # enter apiserver host value here
port: # enter apiserver port value here
client:
token: # enter serviceaccount token value here
#token_file: # enter file path here
```
### Desired State
Need to clarify.

Configurations can be fetched from container env. So you don't have to configure the service discovery settings explicitly.

Ok, I got it, thanks a lot. The service name should be `kube-pre-release/account-svc:http`.
