Containerlab
The purpose of this deployment is to achieve redundancy, high-availability and data aggregation via clustering.
This deployment example includes:
- A 3 instances gNMIc cluster,
- A standalone
gNMIcinstance. - A Prometheus Server
- A Grafana Server
- A Consul Server
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
gNMIccluster instances discover the targets dynamically using a Docker Loader - The
gNMIcstandalone instance, discovers the cluster instance using a Consul Loader - The Prometheus server discovers gNMIc's Prometheus output using Consul Service Discovery
