Hello my friend,
lab testing is one of the crucial parts of any new technology introduction. At the same time, we know that in labs we typically have a lower security requirements. For example, we use SSL certificates, but we don’t have proper PKI and, therefore, certificates are self-signed.

Is GNMI a Good Interface for Network Automation?
Yes, it is. GNMI is one of the most recent interfaces created for the management plane, which allows you to manage the network devices (i.e., retrieve configuration and operational data, modify configuration) and collect the streaming or event-driven telemetry. Sounds like one-size-fits-all, isn’t it? On top of that, GNMI supports also different transport channels (i.e., encrypted and non-encrypted), which makes it suitable both for lab testing and for production environment. You may feel that we are biased to gNMI, and you are right. Actually, that is a reason why we created pyGNMI library, Open Source library for network automation with Python and GNMI.
- Success and failure strategies to build the automation tools.
- Principles of software developments and tools for that.
- Data encoding (free-text, XML, JSON, YAML, Protobuf)
- Model-driven network automation with YANG, NETCONF, RESTCONF, GNMI.
- Full configuration templating with Jinja2 based on the source of truth (NetBox).
- Best programming languages (Python, Bash) for developing automation, configuration management tools (Ansible) and automation frameworks (Nornir).
- Network automation infrastructure (Linux, Linux networking, KVM, Docker).
Anton has a very good and structured approach to bootstrap you in the network automation field.Angel Bardarov @ Telelink Business Services
Moreover, we put all mentions technologies in the context of the real use cases, which our team has solved and are solving in various projects in the service providers, enterprise and data centre networks and systems across the Europe and USA. That gives you opportunity to ask questions to understand the solutions in-depts and have discussions about your own projects. And on top of that, each technology is provided with online demos and you are doing the lab afterwards to master your skills. Such a mixture creates a unique learning environment, which all students value so much. Join us and unleash your potential.
To simplify your work with self-signed certificates, we have introduced back in past the override feature. That feature though required you to provide manually the certificate subject. Today we are introducing the new feature, skip-verify, which brings the simplicity of using the self-signed certificate to a next level. Check out how:
You can watch other demos from pygnmi blogs in our YouTube channel.

You can find this and other examples in our GitHub repository.
pyGNMI became to be used by more and more people and network vendors due to its simplicity and flexibility. If you plan to start doing model-driven network automation leveraging YANG models, gNMI is a good starting point provided your environment supports it. Get in touch with us to learn more. Take care and good bye.
