GitOps intro
GitOps: An Evolution of IaC
GitOps is a concept that enables developers to interact with CI/CD pipelines or Kubernetes clusters in a declarative way—leveraging Git’s powerful collaboration and versioning features.
With GitOps, all environment configurations and Kubernetes application manifests
can be stored in a Git repository and automatically applied by a GitOps controller.
This approach is incredibly powerful because it allows for fully automated workflows,
near-instant deployment of changes, and easy rollback
using git revert
if something goes wrong.
At its core, GitOps can be seen as an evolution of the Infrastructure as Code (IaC) concept.
Key Benefits of GitOps
- Faster and more frequent deployments
- Simple and quick rollbacks
- Full version history of infrastructure changes
GitOps Controllers
The two most widely used GitOps controllers are:
- ArgoCD
- FluxCD
These tools monitor a Git repository for changes and automatically apply updates to the infrastructure.
Why I Use FluxCD in My Homelab
In my homelab, I use Flux because it’s easier to install and offers a more practical learning experience. Unlike ArgoCD, Flux doesn’t have an advanced UI, making it a great tool for getting hands-on experience with GitOps fundamentals.
