zxyao145 opened a new issue, #10096:
URL: https://github.com/apache/apisix/issues/10096
### Current Behavior
In the lua plugin, when using `os.getenv` to get environment variable, the
return value is always nil:
```
local pod_ip
function _M.getpod_ip()
if pod_ip then
return pod_ip
end
pod_ip = os.getenv("POD_IP")
log.error("get pod_ip result: ", pod_ip)
if pod_ip == nil then
pod_ip = "127.0.0.1"
end
return pod_ip
end
```
### Expected Behavior
get environment variables correctly.
### Error Logs
see the picture
### Steps to Reproduce
Code as described above, and use it in plugins.
In my case, it's in the OpenTelemetry plugin and we need to expose the IP
address.
