Picture a Viking jarl showing up at a Renaissance fair. He's out of place by about 500 years, and everyone's staring. I know this feeling firsthand...because I've actually done it. My friends and I showed up to a Renaissance fair in full Viking gear. Wrong era, wrong crowd, and absolutely no regrets. People stared, people laughed, and then people came over to talk to us because we stood out.

That's exactly how most network engineers feel the first time someone suggests they should be using GitHub. Out of place. Like it's not their world. But here's the thing...that Viking belongs there more than you'd think. And so do you.

Did the Vikings really invent Git?

Consider how a jarl actually operated. He didn't sail one ship in one direction and hope for the best. He split his fleet. Each crew took a different route, explored independently, gathered what they could, and then reunited to share what they found. That's branching in Git. You split off from the main line, do your work without disrupting anyone else, and when you're ready, you merge back. The codebase is stronger for it.

The Viking doesn't stop being a Viking just because he walked into a Renaissance fair. And you don't stop being a network engineer just because you opened a repository. You're just raiding smarter.There's a quiet assumption that lives in a lot of network teams: GitHub is a developer thing. It's for the people writing application code, not the people managing switches, firewalls, and routing policies. If you've ever felt that way, I want to challenge it directly. GitHub is one of the most valuable tools a network engineer can adopt today, and the barrier to entry is far lower than you probably think.

Let me walk you through why, and how I actually use it in my own work.

What Is GitHub, Really?

At its core, GitHub is a platform built on top of Git, a version control system. Git tracks changes to files over time. GitHub adds collaboration, visibility, and workflow automation on top of that.

For developers, that means tracking application source code. For network engineers, it means tracking everything else: automation scripts, playbooks, configuration templates, runbooks, and documentation. Anything text-based that you change over time is a candidate for version control.

The mental shift is simple: your Ansible playbooks, your Python scripts, your YAML inventory files, and ot templates...those are beautiful pieces of code. They deserve the same discipline developers apply to their applications.

What are the Benefits?

You Get a Full Change History

Every time you push a change to GitHub, Git records who made it, when, and what changed. If a playbook worked last Tuesday and breaks today, you can diff the two versions in seconds and see exactly what changed. No more "I think someone edited this file last week." This is especially valuable in network automation, where a single typo in a YAML file can affect dozens of devices.

Nothing Gets Lost

How many times has a script lived only on someone's laptop or a shared drive with no backup? GitHub gives your work a permanent, centralized home. If your machine dies, your automation library survives.

You Can Collaborate Without Chaos

Remember the jarl splitting his fleet? That's not just a metaphor, it's exactly how GitHub's branching model works in practice. When multiple engineers work on the same automation codebase, things can get messy fast without a structured way to merge work. Branching lets each person work in isolation, then merge cleanly when the work is ready. Pull requests give you a built-in review process, which is a natural place to catch mistakes before they run in production.

It Forces Good Habits

Writing a commit message forces you to articulate what you changed and why. Over time, a well maintained repo becomes documentation in its own right. New team members can trace the evolution of a playbook just by reading the commit history.

It Integrates With Automation Pipelines

GitHub is the backbone of most modern CI/CD workflows. Tools like AWX (the open-source version of Ansible Tower) can be configured to sync directly from a GitHub repository. That means when you push a change to your playbook, AWX can automatically pull the update. Your repo becomes the single source of truth for what runs in your environment.

How I Use It: Ansible Playbooks for Network Automation

In my environment, I manage network automation workflows that target Cisco ASA firewalls, Cisco NX-OS switches, and many other types of devices..especially in my home lab. A significant portion of that work involves maintaining and deploying Ansible playbooks through AWX. GitHub sits at the center of that workflow.

My automation repository holds everything: playbooks, inventory structures, variable files, and templates. AWX is connected directly to the repo. When I push a tested change, AWX picks it up automatically during its next sync. That tight loop between development and execution removes a lot of manual overhead.

Say you need to update the DNS, NTP, RADIUS, and TACACS server configurations across every device in your environment. Instead of logging into each one manually, you have a playbook for that. It lives in GitHub. You make the change in a branch, test it in a lab segment, and merge it when you're confident. Six months later when someone asks why those servers were changed, the commit history has the answer.

This approach has also been valuable when troubleshooting. If a playbook starts behaving unexpectedly after a change, I can pull up the diff, see exactly what shifted, and either roll back or fix forward. That audit trail has saved hours of guesswork.

Getting Started Without the Overwhelm

You do not need to learn everything at once. Here is a realistic starting path:

Start With What You Already Have

Take an existing script or playbook and put it in a repository. Even just having it in GitHub with a commit history is a significant improvement over a file sitting on a server somewhere.

Learn Five Commands

The daily GitHub workflow for most use cases comes down to git clone, git pull, git add, git commit, and git push. Master those and you're functional.

Use VS Code

Visual Studio Code has excellent built-in Git integration. You can stage, commit, and push without touching the command line, which removes a lot of friction when you're getting started.

Treat Your Repo Like Infrastructure

Write clear commit messages. Use branches for changes that aren't ready to run. Review your own pull requests before merging. These habits compound over time.

Connect It To Your Tooling

If you're using AWX or any CI/CD-adjacent tooling, configure it to sync from GitHub. That integration is where the real value starts to show up.

The Bigger Picture

Network engineering is changing. The line between infrastructure and software continues to blur. As-code workflows, infrastructure as code, and network as code are not a trend that's going to reverse. The engineers who stay ahead are the ones who are comfortable with the tools that make those workflows possible.

GitHub is one of those tools. It is not complicated once you start using it, and the benefits show up fast. Version control, collaboration, and pipeline integration are not developer luxuries. They are foundational disciplines for any engineer managing complex, large scale, and changing systems.

If your playbooks, scripts, and templates are not in version control yet, the best time to start is now. The second best time is still now.
