Containerlab
The purpose of this deployment is to collect gNMI data and write it to a NATS server.
Multiple 3rd Party systems (acting as a NATS clients) can then read the data from the NATS server for further processing.
This deployment example includes a single gnmic instance and a single NATS output
Deployment files:
The deployed SR Linux nodes are discovered using Docker API and are loaded as gNMI targets. Edit the subscriptions section if needed.
Deploy it with:
git clone https://github.com/openconfig/gnmic.git
cd gnmic/examples/deployments/1.single-instance/1.nats-output/containerlab
sudo clab deploy -t nats.clab.yaml
