GitOps and Infrastructure as Code#

GitOps says: the desired state is in Git. A controller continuously reconciles the real state to match. Infrastructure as Code says: the desired state is in code. A human (or agent) runs apply to push changes.

These two paradigms overlap but do not align perfectly. Kubernetes resources fit the GitOps model well — ArgoCD/Flux watch Git, detect differences, and apply changes continuously. Cloud infrastructure (VPCs, databases, IAM roles) fits the IaC model better — Terraform tracks state, computes diffs, and applies on command.

Integrating Infrastructure as Code with CI/CD#

Running Terraform locally works for one person. It breaks down when multiple people (or agents) modify infrastructure concurrently, when changes need review before applying, and when environments (dev/staging/prod) need synchronized promotion. CI/CD pipelines solve this by making the plan-review-apply cycle automated, auditable, and safe.

This article covers the patterns for integrating Terraform into CI/CD — from the basic plan-on-PR flow to multi-directory monorepos with dependency ordering and environment promotion.

GitOps for Kubernetes#

GitOps is a deployment model where git is the source of truth for your cluster’s desired state. A controller running inside the cluster watches a git repository and continuously reconciles the live state to match what is declared in git. When you want to change something, you commit to git. The controller detects the change and applies it.

This replaces kubectl apply from laptops and CI pipelines with a pull-based model where the cluster pulls its own configuration. The benefits are an audit trail in git history, easy rollback via git revert, and drift detection when someone makes manual changes.
