⚡ Phase 5 · Network Automation & CI/CD Pipelines

🚀 Infrastructure-as-Code & NetDevOps Masterclass: Bridge the gap from traditional CLI network engineering to modern software-driven network automation, automated testing, and CI/CD pipelines.

🏛️ Course Architecture & NetDevOps Roadmap

Traditional CLI network management is slow, prone to human error, and doesn't scale. In Phase 5, you learn how hyperscale network teams (Google, Meta) manage network infrastructure as code (IaC), generate configurations programmatically, validate network policies before deployment, and execute automated test pipelines on GitHub Actions:

Phase 5 · Network Automation & CI/CD Pipelines
├── 🧪 Lab 01 · Data-Driven Config Generation (Jinja2 & YAML Data Models)
├── 🧪 Lab 02 · Automated Network Verification (Cisco PyATS / Genie Framework)
├── 🧪 Lab 03 · Pre-Deployment Policy Verification (Batfish Pre-Flight Analysis)
├── 🧪 Lab 04 · Programmatic Telemetry & State Parsing (gNMI / pygnmi)
└── 🧪 Lab 05 · Containerlab CI/CD Pipelines in GitHub Actions

🧠 Why NetDevOps for Network Engineers?

If you have spent your career typing CLI commands (configure terminal, interface Ethernet1, ip address ...), software automation can seem intimidating. Phase 5 starts from first principles and explains every concept step-by-step:

Traditional CLI Network Engineering	Modern NetDevOps Software Engineering
Hand-crafted CLI commands per router	Data Models (YAML) + Templates (Jinja2)
Manual show commands to check status	Automated Test Suites (PyATS / Genie)
Testing changes live on production devices	Pre-Flight Static Analysis (Batfish)
Periodic SNMP polling (UDP 161)	Streaming Telemetry (gNMI / gRPC)
Manual change requests & maintenance windows	Automated CI/CD Pipelines (GitHub Actions)
