### Description Hello, I try to configure APISIX to implement canary deployment on microservices registered to Consul. Basically, - I register multiple service instances sharing the same logical "service name" on Consul - I tag every instance (using tags or metadata) to differentiate "_stable_" instances from "_canary_" instances. See below an example of Consul registration: ``` # Register stable my_service instance curl -X PUT http://localhost:8500/v1/agent/service/register -H "Content-Type: application/json" \ -d '{ "ID": "my_service_stable", "Name": "my_service", "Address": "192.xxx", "Tags": ["stable"], "Meta": { "version": "stable" } }' # Register canary my_service instance curl -X PUT http://localhost:8500/v1/agent/service/register -H "Content-Type: application/json" \ -d '{ "ID": "my_service_canary", "Name": "my_service", "Address": "192.xxx", "Tags": ["canary"], "Meta": { "version": "canary" } }' ``` On Consul, it looks like: <img width="1091" height="540" alt="Image" src="https://github.com/user-attachments/assets/298a3aa8-ab9d-44a5-98c5-3f2e33ff1481"; /> Then, on APISIX, I would like to split my traffic according to these tags or metadata values. Something like: (_metadata_match_ is here for illustration only; it's the purpose of this issue) ``` curl -H "X-API-KEY: $APISIX_ADMIN_KEY" -X PUT http://localhost:9180/apisix/admin/routes/route_my_service \ -d '{ "uri": "/my_service", "plugins": { "traffic-split": { "rules": [ { "weighted_upstreams": [ { "weight": 80, "upstream": { { "type": "roundrobin", "service_name": "dummy", "discovery_type": "consul", "discovery_args": { "metadata_match": { "version": ["stable"] } } } } }, { "weight": 20, "upstream": { { "type": "roundrobin", "service_name": "dummy", "discovery_type": "consul", "discovery_args": { "metadata_match": { "version": ["canary"] } } } } }, ] } ] } } }' ``` Unfortunately, filtering/matching seems not to be supported now; am I right? So currently, the only way I found so far is to create separate services on Consul (one named _stable_ and one named _canary_) but it's a workaround (Consul service registry is made to group all service instances into a common logical service). In the APISIX git history, I found [this commit](https://github.com/apache/apisix/blob/b61504bb4199f7683ad3f7bc6a1fabfc7d0ea30a/t/discovery/consul.t#L855-L997) that was illustrating what I wish by a test; is this feature already coded? planned? Thank you for your great work. Best regards -- This is an automated message from the Apache Git Service.
