Consul Discovery

The Consul target loader discovers gNMI targets registered as service instances in a Consul Server.

The loader watches services registered in Consul defined by a service name and optionally a set of tags.

Services watch#

When at least one service name is set, gNMIc consul loader will watch the instances registered under that service name and build a target configuration using the service ID as the target name and the registered address and port as the target address.

The remaining configuration can be set under the service name definition.

loader:
  type: consul
  services:
    - name: cluster1-gnmi-server
      config:
        insecure: true
        username: admin
