Understanding GitOps: Principles, Workflow, and Benefits

GitOps provides an automated way to manage infrastructure by leveraging familiar DevOps practices like version control, code review, and CI/CD pipelines.

How GitOps Works

The concept originated from Weaveworks and is closely tied to Kubernetes. It revolves around three main components: Infrastructure as Code, Pull Requests, and CI/CD.

Infrastructure as Code

Infrastructure is defined as declarative code stored in Git repositories, allowing teams to describe the desired state of systems (e.g., Kubernetes manifests) and let the platform reconcile the actual state automatically.

Pull Requests

Git serves as the single source of truth; changes to infrastructure are made via pull requests, enabling code review, auditability, and transparent collaboration.

Git Organization

Typically two repositories are used: an application repository containing source code and deployment manifests, and an environment configuration repository describing the desired state for each environment (dev, test, prod). Branches and pull requests manage changes across these repos.

CI/CD

A CI/CD pipeline applies infrastructure changes whenever the Git repository is updated. Two deployment strategies exist:

Push pipelines build artifacts and push them to environments directly.

Pull pipelines use an operator that continuously reconciles the actual state with the desired state defined in the environment repo, offering a safer, more declarative approach.

Benefits of GitOps

Leverages existing DevOps best practices for cloud‑native applications.

Simplifies continuous deployment, reducing manual effort and increasing deployment frequency.

Lowers MTTR by providing full version history and automated rollbacks.

Makes Kubernetes management easier for developers familiar with Git.

Improves organization‑wide standardization and transparency.

Preparing for GitOps

Establish robust code review and testing processes.

Implement thorough testing before changes are merged.

Focus on monitoring to detect drift and ensure system stability.

Adopt a DevOps culture that encourages collaboration between development and operations.

Why Choose GitOps?

GitOps offers a streamlined workflow for managing cloud infrastructure, providing better coordination, transparency, stability, and durability for engineering teams.
