discovery_args not work in upstream when using nacos #12392
Description
Description
apisix: 3.13.0
configure nacos as discovery tool, and in one service, specify a metadata as lane:laneA, second machine didn't specify this param, I hope discovery_args can filter out correct Ip(which metadata include lane), but it didn't.
route/upstream configuration.
{
"id": "l-swagger-demo",
"priority": 20,
"uri": "/*",
"vars": [
["http_lane", "==", "laneA"]
],
"upstream": {
"type": "roundrobin",
"discovery_type":"nacos",
"service_name":"l-swagger-demo",
"discovery_args":{
"metadata": {
"lane":"laneA"
}
}
},
"plugins": {
"proxy-rewrite": {
"headers": {
"X-Lane": "$http_lane"
}
}
}
}and this is result when I query l-swagger-demo from nacos. above condition didn't work.
Can anyone help??? Thanks a lot.
