GitOps – Definition, Use Cases and Best Practices at a Glance
GitOps is an operations and deployment approach in which the desired state of applications and infrastructure is described in Git, versioned, and synchronised automatically into the target environment. Git thus becomes the central source of truth.
GitOps: Definition & How It Works | Glossary
Who hasn't heard "it still worked on my machine"? GitOps makes such surprises unlikely by consistently describing the desired state of applications and infrastructure in Git.
Instead of manual changes on servers, every change becomes visible as a commit, is reviewed and brought into the target environment automatically. This makes deployments traceable, repeatable and auditable – a big win for stability and compliance.
This glossary entry for GitOps gives you a clear Definition, practical Use Cases and Best Practices at a glance – with examples, pros and cons, and FAQs.
What is GitOps?
- GitOps is an operations and deployment approach in which the desired state of applications and infrastructure is described in Git, versioned, and synchronised automatically into the target environment. Git thus becomes the central source of truth.
GitOps is an approach to deployment and operations in which the desired target state of applications and infrastructure is stored declaratively and versioned in a Git repository.
An automation mechanism continuously compares the actual state of the target environment with the desired state described in Git and reconciles deviations automatically.
The difference from classic CI/CD matters: CI/CD describes the pipelines through which code is built and shipped; GitOps makes Git the authoritative source of truth for the target state.
Changes no longer happen manually on servers but as a commit or pull request – with review, history and rollback capability. Typical elements are a Git repository, declarative configuration, a synchronisation mechanism, rollback capability, auditability and a clear permissions model.
GitOps is often used in connection with Kubernetes, Infrastructure as Code and cloud operations.
How does GitOps work?
In the GitOps model, the desired state of the environment is described declaratively – which application versions, configurations and resources should run – and versioned in a Git repository. To change something, this happens via a pull request: the change is reviewed, approved and merged.
An automation tool detects the change in the repository and synchronises the target environment automatically to the new desired state. If the environment deviates from the described state – for example through a manual intervention – the tool detects this drift and can correct it.
Since every change exists as a commit, history, accountability and rollback are always available: an earlier state can be restored by reverting the repository. This creates traceable, repeatable operations.
Practical Examples
A new application version is described via a pull request; after the merge, the system rolls out the change automatically.
A server changed manually by mistake is detected by the GitOps tool and reset to the state described in Git.
After a faulty release, the previous state is quickly restored by reverting the repository.
Infrastructure and application configuration are versioned together in Git, so environments are built reproducibly.
Audits become easier because every change exists as a traceable commit with author and timestamp.
Typical Use Cases
Operating applications on Kubernetes with declarative configuration
Managing infrastructure as code with versioning and review
Reproducible setup of multiple environments (dev, staging, production)
Traceable deployments with rollback capability
Compliance and audit requirements for change records
Reducing manual interventions and configuration drift
Advantages and Disadvantages
Advantages
- Git as the central source of truth: every change is traceable
- Repeatable, reproducible operations across multiple environments
- Easy rollback by reverting the repository
- Fewer manual interventions and thus less configuration drift
- Better compliance through a complete change history and permissions model
Disadvantages
- Introduction effort and required standards for declarative configuration
- Requires discipline: no manual interventions on the system
- For very small projects the approach can be oversized
- Requires know-how in Git, automation and possibly Kubernetes
- Misconfigurations in the repository affect the environment automatically
Frequently Asked Questions about GitOps
What is the difference between GitOps and CI/CD?
CI/CD describes the pipelines through which code is built and shipped. GitOps makes Git the authoritative source of truth for the target state of applications and infrastructure and reconciles the environment to it automatically.
Which elements belong to GitOps?
Typical are a Git repository as the source of truth, declarative configuration, an automatic synchronisation mechanism, rollback capability, auditability and a clear permissions model.
Does GitOps strictly require Kubernetes?
No, GitOps is often used with Kubernetes but is not limited to it. The core – a declarative target state in Git and automatic synchronisation – can be applied to other environments too.
How does a rollback work in GitOps?
Since the target state is versioned in Git, it is enough to revert the repository to an earlier state. The automation tool then synchronises the environment automatically to that previous state.
Who benefits from GitOps?
Especially teams with multiple environments, high requirements for traceability and compliance, and operations on Kubernetes. For very small projects the effort may exceed the benefit.

GitOps in the Context of Modern IT Projects
What this glossary entry gives you
This page gives a concise definition of GitOps. You also get practical use cases and best practices at a glance.
You can use it to evaluate the technology for your next project. GitOps sits in the domain of DevOps. It plays a significant role across many IT projects.
Look beyond isolated technical merits
When you judge whether GitOps is the right fit, look beyond isolated technical merits. You should weigh the full project context.
Consider the following factors:
- Existing team expertise
- Current infrastructure
- Long-term maintainability
- Total cost of ownership (TCO)
Drawing on our experience from over 250 software projects, we have found that correctly positioning a technology or methodology within the broader project context often matters more than its isolated strengths.
How we help you decide
At Groenewold IT Solutions, we have worked with GitOps across multiple client engagements. We know its advantages and the typical challenges during adoption.
If you are unsure whether GitOps suits your requirements, ask us for an honest, no-obligation assessment. We analyze your situation. We recommend the approach that delivers the most value. We may suggest an alternative solution if that fits better.
