GitOps

What Is GitOps?

GitOps is a software delivery practice that uses Git as the source of truth for application and infrastructure configuration. It automatically brings live environments into line with approved, version-controlled configuration. GitOps is an operating model, not a single tool: the repository records the desired state, while automation applies and maintains it.

How GitOps Works

GitOps turns a reviewed configuration change into a controlled deployment process.

1. Define the desired application or infrastructure state in declarative files.
2. Propose a change through a pull request.
3. Run validation, tests, and policy checks before approval.
4. Merge the approved change into the target Git branch.
5. Let a deployment agent pull and apply that approved state.
6. Continuously check for drift and restore the declared state when needed.

The Four GitOps Principles

The OpenGitOps principles explain what separates GitOps from simply storing scripts in Git.

• Declarative: files describe the result wanted, such as a service with three running copies.
• Versioned and immutable: approved changes have a traceable history and should not be silently altered.
• Pulled automatically: an agent in or near the target environment retrieves approved configuration.
• Continuously reconciled: the agent compares reality with Git and corrects configuration drift.

GitOps vs DevOps vs CI/CD

These practices overlap, but they solve different parts of software delivery.

Benefits of GitOps

GitOps makes operational changes easier to inspect and repeat.

• Git history creates a clear audit trail of who approved each change.
• Reviewed configuration produces more consistent environments.
• Rollback can be simple: revert a faulty configuration commit, then let the agent restore the earlier state.
• Continuous reconciliation reduces unnoticed drift caused by manual production edits.

Practical Limits and Risks of GitOps

GitOps needs setup, discipline, and operational safeguards.

• Secrets should not be stored as readable values in a repository.
• Direct production edits can be overwritten, so teams need clear emergency-change procedures.
• Repository permissions and branch protection are security controls, not optional administration.
• Stateful database or data migrations may need carefully tested, ordered steps.
• Monitoring and tested rollback plans remain necessary when automation fails.

GitOps Tools and Pull-Based Reconciliation

Git hosting records changes, CI validates them, and infrastructure-as-code tools define resources. Reconciliation agents such as Argo CD and Flux watch Git and pull approved state into an environment, which is why Argo CD is considered a GitOps tool. This differs from a push-based pipeline that sends credentials and changes directly into production.

Using GitOps When Building with Emergent

Teams building through AI app builder workflows can keep deployment definitions and environment configuration under the same review discipline as application code. Emergent accelerates app design and development, testing, integrations, and shipping, while GitOps provides a repeatable way to manage approved releases.
