[GitHub] [apisix] qlql489 opened a new issue, #8535: help request: how to lossless update upsteam service in k8s
qlql489 opened a new issue, #8535:
URL: https://github.com/apache/apisix/issues/8535
### Description
i config router use node type, the value is k8s's service host, like this:
```
"nodes": [
{
"host": "push-api",
"port": 80,
"weight": 1
}
]
```
the upstream service deploy at list two pod ,when i update upstream service ,will cause some requsts faill, return code 502
i guess is the upsteam's keepalive config, the old connection is not close, i try to modify the config like this , it works ， but It affects performance and is not elegant，have other solution to solve the problem?
```
upstream apisix_backend {
server 0.0.0.1;
balancer_by_lua_block {
apisix.http_balancer_phase()
}
# keepalive 320;
# keepalive_requests 1000;
# keepalive_timeout 60s;
# we put the static configuration above so that we can override it in the Lua code
}
```
### Environment
- APISIX version (2.13.1):
- Operating system (linux):
- OpenResty / Nginx version (openresty/1.19.9.1):

@tzssangglass Here seems that he didn't use the service discovery.
@qlql489 This may be due to APISIX doesn't know that your pods are drifting. So it still reuses the connections in the keepalive pool. Try enabling `proxy_socket_keepalive`.
