Hey folks, here I am this time after not that long time with another post about what seems to be one of the often asked questions during DevOps interviews, “What is GitOps”. It’s almost 3 am for me as I am writing this one so I will try to keep it as short as possible.
The world of software development never stops changing, and we’re always looking for better ways to get things done of course. One of the latest buzzwords (besides AI of course) is GitOps. In this short blog post, I will try to break down what GitOps is, its key principles, and how it can make your life as a developer and DevOps easier and more efficient, at least in a theory. Yeap, I know you are laughing.
What is GitOps?
GitOps is kind of a cool way to manage your infrastructure and applications by using only Git as the go-to place for both code and infrastructure. It brings together the best of DevOps, version control, and continuous delivery to create a more streamlined and reliable software development process. So in theory, it should make your life easier. In my head, I see it more as an idea or methodology than the technique itself honestly.
Idea behind GitOps
GitOps is built on a few core ideas that make it a game-changer for IT folks:
- Git is King: GitOps uses Git as the central source for all your code and infrastructure, which means every change is tracked, easy to audit, and can be rolled back if needed logically.
- Declarative Infrastructure: I am sure you might think this might be a step back but with GitOps, you describe what you want your infrastructure to look like in a simple, human-friendly way. This makes it easier to understand, maintain, and fix when things go wrong, and much easier to follow.
- Always Ship: GitOps is all about automation, which means your infrastructure is continuously updated to match the latest changes in your code, but honestly this is kinda to be expected, not sure why I am mentioning it.
- Keep Watching: GitOps encourages you to keep tabs on your infrastructure with monitoring and logging. This way, you’ll know right away if something isn’t quite right and can fix it faster.
Why Is GitOps Amazing?
Adopting GitOps can make a huge difference in your development and deployment process:
- Teamwork Makes it Better: GitOps makes it easy for everyone on the team to work together, with a clear history of all changes. This means developers, operations folks, and security teams can all stay on the same page and not struggle to follow each other.
- No More Oopsies: GitOps practices help reduce the chance of human error, making your infrastructure more reliable and stable. FYI this doesn’t mean it’s 100% human-proof. Nothing is.
- Security: With GitOps, every change to your infrastructure is tracked separately, making it easier to spot potential security issues and fix them faster. Additionally, you could insert a scanning process or some SAST tools.
- Quick Revert: GitOps makes it simple to undo changes and recover from problems, keeping your infrastructure up and running.
- Scalable: GitOps provides a consistent way to manage your infrastructure, so it’s easier to scale and adapt as things change.
Did I convince You to Try GitOps?
If I did then here is how to get started quickly:
- Pick a version control system (like Git) to keep track of your code and infrastructure.
- Start using a declarative approach to describe your infrastructure.
- Set up a continuous delivery pipeline to automatically deploy changes.
- Keep an eye on your infrastructure with monitoring and logging tools.
GitOps is a fantastic way to manage your infrastructure and make your development and deployment process faster, smoother, more secure, and more scalable. By using Git as the one-stop-shop for your code and infrastructure, and focusing on automation and transparency, you’ll be on your way to mastering GitOps in no time.
