Nobilta opened a new issue, #7650:
URL: https://github.com/apache/apisix/issues/7650
### Description
i set upstream discovery kubernetes type , but it not work.when i access a
path(i had set route), i got a error code like this:503 Service Temporarily
Unavailable.
and the error log like this:
`[error] 17748#17748: *849588 [lua] init.lua:540: http_access_phase():
failed to set upstream: no valid upstream node: nil, client: 192.168.92.100,
server: _, request: "GET /apisix/index.html HTTP/1.1", host:
"192.168.92.101:9080"
`
i change the source code to confirm if the ip had added and i got the log
like this:
`on_modified(): #######10.245.2.21 80 50, context: ngx.timer`
its mean that the correct ip has be added because this is the pod ip in
kubernetes.
and if i set the upstream in nodes mod,it also works(use pod ip directly)
this's the upstream set
```
{
"uri": "/apisix/*",
"name": "",
"upstream": {
"type": "roundrobin",
"hash_on": "vars",
"scheme": "http",
"discovery_type": "kubernetes",
"pass_host": "pass",
"service_name": "nginx-service"
},
"status": 1
}
```
so i want to know how i should do to fix it
