Over the past episodes, we have built a strong understanding of GitOps: from basic application deployments to creating scalable, production-ready workflows.
But true operational excellence means preparing for the unexpected.
Clusters will fail. Mistakes will happen. Infrastructure needs will evolve.
In this final episode of our GitOps journey, we will explore how GitOps helps us recover from disasters, safely roll back changes, and even extend GitOps practices to manage not just applications but entire cloud infrastructures.
Let’s bring it all together.
Disaster Recovery with GitOps
In traditional systems, disaster recovery often means scrambling to locate backups, manually rebuilding servers, or trying to reconstruct environments from memory. This process is slow, risky, and prone to inconsistencies. Even with perfect backups, restoring configurations, dependencies, and application states can take hours or even days.
GitOps introduces a fundamentally better model.
Because all infrastructure and application state is stored declaratively in Git, recovery becomes a predictable, repeatable process. If your Kubernetes cluster is lost due to hardware failure, human error, or any other disaster, recovery follows a simple flow:
First, you provision a basic new cluster. This could be a cloud Kubernetes service like GKE, EKS, or AKS, or even a local cluster if needed.
Second, you reinstall FluxCD — the GitOps controller — onto the new cluster.
Finally, you reconnect Flux to your existing Git repository that contains all your application and environment definitions.
At that point, Flux will automatically begin synchronizing the new cluster with the desired state stored in Git.
Applications, services, ingress controllers, monitoring stacks, and even secrets (if encrypted properly) are all restored — automatically, declaratively, reliably.
In short:
Git becomes your living backup.
Recovery becomes not a frantic scramble, but a disciplined restoration from code.
This shift dramatically improves operational resilience. It means that recovery time objectives (RTOs) can be minutes instead of hours, and it means that your infrastructure is no longer a fragile snowflake — it is codified, reproducible, and safe.
Handling Rollbacks with GitOps
Even without full disasters, operational mistakes are inevitable.
An updated service might introduce a regression. A misconfigured deployment could cause cascading failures. In traditional deployments, rolling back can be messy — redeploying artifacts manually, restoring from partial backups, or recreating resources by hand.
GitOps changes the rollback story completely.
Since every deployment, every configuration change, every version update is committed to Git, rolling back is as simple as reverting Git history.
If a deployment introduces a bug, you don’t need to remember arcane rollback commands.
You simply find the last known good commit, perform a git revert, and push the change.
Flux sees the updated Git state and applies it automatically, restoring the previous healthy configuration.
This model makes rollbacks:
- Safe — because Git enforces correctness
- Auditable — every change and revert is logged
- Predictable — no manual scripts or hidden state
It also encourages better operational hygiene: teams know that any change they make must be safely revertible, and reviews naturally focus on stability and risk.
GitOps treats rollback not as an emergency exception but as a normal, first-class operation.
Extending GitOps to Infrastructure Management
So far, we’ve focused on managing Kubernetes resources: deployments, services, ingresses, and so on.
But GitOps principles don’t have to stop at the application layer.
Modern infrastructure — VPCs, databases, managed Kubernetes clusters, load balancers, firewalls — can and should also be managed as code.
This is where Infrastructure as Code (IaC) tools like Terraform come in.
Terraform allows you to define your entire infrastructure declaratively, much like Kubernetes manifests define applications. A Terraform configuration describes the desired state of your infrastructure — and Terraform plans and applies changes to match reality to that desired state.
In GitOps workflows, there are two common patterns to integrate Terraform:
First, the pull request-based model. Teams store Terraform configurations in Git repositories.
Infrastructure changes happen through PRs: review, approve, merge — then trigger a Terraform plan and apply via automation tools like GitHub Actions, GitLab CI, or dedicated Terraform pipelines.
This keeps Git as the source of truth and ensures infrastructure changes are auditable and controlled.
Second, newer tools like the FluxCD Terraform Controller allow even deeper integration.
With the Terraform Controller, infrastructure management becomes a true GitOps process: Flux monitors Terraform configs in Git, applies changes declaratively, and ensures that infrastructure remains reconciled — just like Kubernetes resources.
This approach enables complete, unified GitOps:
Applications and infrastructure, all managed through Git, all reconciled automatically, all safely auditable.
By extending GitOps to infrastructure, you gain a single operating model for your entire cloud system — simple, powerful, and scalable.
Conclusion — Completing the GitOps Journey
As we close this series, it’s worth stepping back to see how far we’ve come.
GitOps began as a simple idea: use Git as the single source of truth for Kubernetes applications. But as we explored, GitOps is far more than a deployment method — it’s a complete operational model for modern cloud-native systems.
By mastering GitOps, you gain:
- Automation of deployments and updates
- Security through encrypted secrets and controlled workflows
- Collaboration through Git-centric team practices
- Scalability across multiple clusters and teams
- Resilience through disaster recovery and rollback strategies
- Unified management of both applications and infrastructure
GitOps is not just a trend — it’s a foundational shift in how modern systems are built, operated, and evolved.
Congratulations on completing this GitOps journey!
You are now equipped not only to deploy applications declaratively but to build resilient, scalable, production-grade platforms — powered by code, collaboration, and automation.
And of course, this is just the beginning. Future topics like GitOps security hardening, multi-cloud GitOps, ArgoCD vs Flux deep-dives, and advanced scaling strategies await.
Until then, keep shipping, keep automating — and keep everything in Git.
