Containerlab

The purpose of this deployment is to achieve redundancy, high-availability and data aggregation via clustering.

This deployment example includes:

The leader election and target distribution is done with the help of a Consul server

All members of the cluster expose a gNMI Server that the single gNMIc instance will use to aggregate the collected data.

The aggregation gNMIc instance exposes a Prometheus output that is registered in Consul and is discoverable by the Prometheus server.

The whole lab is pretty much self organising:

  • The gNMIc cluster instances discover the targets dynamically using a Docker Loader
  • The gNMIc standalone instance, discovers the cluster instance using a Consul Loader
  • The Prometheus server discovers gNMIc's Prometheus output using Consul Service Discovery
