Understanding GitOps: Principles, Workflow, and Benefits

What is GitOps?

GitOps provides an automated way to manage infrastructure by applying familiar DevOps best practices—version control, code review, and CI/CD pipelines—to infrastructure configuration.

While DevOps has greatly improved productivity and software quality, infrastructure provisioning and deployment often remain manual. GitOps lets teams automate the configuration process by storing infrastructure as code (IaC) in Git repositories, just like application code.

How does GitOps work?

The concept originated at Weaveworks and is closely tied to Kubernetes. It revolves around three main components:

Infrastructure as Code

Pull Requests

CI/CD

Infrastructure as Code

IaC treats infrastructure configuration as declarative files stored as code. In a declarative model, you describe the desired state rather than issuing imperative commands. For example, a Kubernetes manifest can declare the number of Pods a service should have, and the system reconciles the actual state automatically.

Any cloud‑native software that follows a declarative model can be treated as code; AWS CloudFormation is a typical example, allowing the entire infrastructure to be expressed as code and applied automatically.

Pull Requests

The core idea is that the Version control system is the single source of truth. Changes to infrastructure are made via pull requests, enabling code review before merging. This review process prevents undesirable changes from reaching test or production environments and provides a clear audit trail.

Just like application development, a main branch represents the production state, feature branches are used for changes, and pull requests merge those changes back after approval.

Git Organization

GitOps typically uses two repositories: an application repository (source code and deployment manifests) and an environment configuration repository (declarative specifications of the desired state for each environment). Branches can represent different environments (dev, test, prod), and pull requests coordinate changes across them.

GitOps works with any Git‑based platform (GitHub, Bitbucket, GitLab) and does not depend on a specific tool.

CI/CD

A CI/CD pipeline is required to deliver infrastructure changes automatically whenever the Git repository is updated. Two deployment strategies exist:

Push Pipeline

Most CI/CD tools use this approach: the pipeline builds container images and pushes changes directly to the target environment after a code change is detected.

While flexible, this method gives the CI/CD tool write access to the environment.

Pull Pipeline

The community often prefers the pull‑based approach for safety. An operator continuously compares the desired state in the environment repository with the actual state in the cluster. If a drift is detected, the operator reconciles the infrastructure to match the repository.

Updates occur only when the environment repository changes, and any out‑of‑band modifications are automatically rolled back.

Benefits of GitOps

Leverages DevOps Best Practices

GitOps builds on existing DevOps practices—Git workflows, IaC, CI/CD pipelines, immutable servers, observability—providing a higher‑level model for managing cloud‑native applications on Kubernetes.

Simplified Continuous Deployment

Continuous deployment becomes faster and more frequent because the entire process is driven by version‑controlled pull requests and automated operators, reducing manual effort and increasing productivity.

Reduced MTTR (Mean Time to Recovery)

Since every change is versioned and automated, incidents can be traced and rolled back quickly, significantly lowering the mean time to recovery.

Easier Kubernetes Management

Developers can manage Kubernetes upgrades and features using familiar Git tools without deep Kubernetes expertise, accelerating onboarding.

Enterprise‑wide Standardization

GitOps creates a transparent, end‑to‑end workflow that can be replicated across the organization, ensuring consistent operational standards.

Preparing for GitOps

Establish robust code review and testing processes to prevent faulty changes from reaching production.

Test, test, test – thorough automated testing is essential for reliable rollouts.

Focus on monitoring – continuous observability helps detect drift and maintain system health.

Embrace a DevOps culture – collaboration between development and operations is key to realizing GitOps benefits.

Why Choose GitOps?

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