Side build

Multi-env GitOps Platform

A fully automated, GitOps-driven Kubernetes platform that runs on a laptop. Terraform bootstraps the cluster and ArgoCD, and Git is the only way anything reaches an environment.

The problem

Learning the full delivery chain usually means a cloud bill and an account someone else controls. Tutorials each cover one link, so the interesting parts, like who may change prod and what happens when a release is wrong, never come up.

What I built

  • k3d cluster provisioned by Terraform, with ArgoCD owning every workload through an app-of-apps.
  • CI builds multi-arch images to GHCR and commits the new tag to a dedicated GitOps repository.
  • Dev takes every build. Prod changes only through a reviewed pull request behind CODEOWNERS.
  • Argo Rollouts canary that pauses for a human judgment before completing.
  • An optional managed EKS cluster can run the same platform from the same repository.
