This article presents an architectural approach for automatically bootstrapping core services in Kubernetes clusters using GitOps principles, with Flux CD as the reconciliation engine. The primary goal is not maximum abstraction or infinite scalability, but a clear, maintainable, and operationally practical foundation that enables a cluster to become usable quickly and remain easy to reason about over time. The scope of this article is intentionally architecture‑focused. It describes how responsibilities, dependencies, and isolation boundaries are modeled declaratively - across repositories, directories, namespaces, and Flux resources - rather than how to provision infrastructure or tune workloads. Kubernetes itself is assumed to be operational up to the networking layer. ...

This article presents a CI/CD process for Infrastructure‑as‑Code using Terragrunt with Terraform/OpenTofu. The goal is to enable safe, efficient, and consistent infrastructure changes through a structured workflow. The process is motivated by a few key needs: allowing multiple developers to work in parallel enforcing segregation‑of‑duty through pull requests and approvals enabling lean deployments by targeting only changed units instead of full stacks maintaining infrastructure consistency between the codebase and the actual infrastructure Such a workflow only works when both the tooling and the team follow the CI/CD principles reliably. ...

Managing infrastructure with Terraform/OpenTofu and Terragrunt can quickly become complex - especially as environments, teams, and requirements grow. Having a transparent, readable, and DRY (Don’t Repeat Yourself) repository structure is essential for maintaining scalability and manageability over time. The approach described here has been proven across real-world projects ranging from a few dozen to several hundred Terragrunt units. It’s adaptable to any setup and built around a hierarchical structure that makes it easy to configure, extend, and reuse components. ...

As a developer, I’ve spent many hours working with infrastructure-as-code tools, helping automate and manage cloud environments. Over the years, I’ve grown fond of Terraform in combination with Terragrunt. Terragrunt serves as a thin wrapper over Terraform, providing additional functionality to help automate complex workflows and encapsulate Terraform modules. When working with Terragrunt, it does not take long to find out about the the run-all feature (see: https://terragrunt.gruntwork.io/docs/reference/cli-options/#run-all), which allows me to run multiple Terraform modules in a single call. This functionality for me has proved invaluable in CI/CD pipelines. ...
