Automating AWS EKS Hosting with GitLab, OpenTofu, and Argo CD
Manual cloud setup remains a persistent pain point for hosting buyers and operators. Network borders, subnet design, IAM credentials, and Kubernetes control planes are easy to misconfigure, and drift between staging and production can cause outages. A recent GitLab tutorial—based on a live demo at AWS Summit Madrid 2025 by Clober (SATEC group)—shows a different path: use GitLab as the single control plane for AWS infrastructure and application delivery. By combining OpenTofu for infrastructure as code, GitLab CI/CD for orchestration, and Argo CD for GitOps, teams can provision an Amazon EKS cluster and deploy a web application without manual console clicks. This matters for sysadmins, agency hosts, and power users who need reproducible, auditable environments. Why Infrastructure as Code and GitOps Matter for Hosting Teams Infrastructure as code (IaC) turns networking, compute, and Kubernetes clusters into versioned files. The GitLab example stresses three properties: environments be...
