The performance of this module needs to be improved:
Add following configuration in conf/config.yaml :
discovery: nacos: host: - "http://${username}:${password}@${host1}:${port1}" prefix: "/nacos/v1/" fetch_interval: 30 # default 30 sec # `weight` is the `default_weight` that will be attached to each discovered node that # doesn't have a weight explicitly provided in nacos results weight: 100 # default 100 timeout: connect: 2000 # default 2000 ms send: 2000 # default 2000 ms read: 5000 # default 5000 ms
And you can config it in short by default value:
discovery: nacos: host: - "http://192.168.33.1:8848"
Here is an example of routing a request with an URI of “/nacos/*” to a service which named “http://192.168.33.1:8848/nacos/v1/ns/instance/list?serviceName=APISIX-NACOS” and use nacos discovery client in the registry:
:::note You can fetch the admin_key from config.yaml and save to an environment variable with the following command:
admin_key=$(yq '.deployment.admin.admin_key[0].key' conf/config.yaml | sed 's/"//g')

The formatted response as below:

Nacos service discovery also supports use in L4, the configuration method is similar to L7.
