Configuring cloud environments is complex, so this tutorial demonstrates automating setup using GitLab. Infrastructure as Code (IaC) and GitOps are key to achieving reproducible, versioned, and automated environments. GitLab integrates source code management, CI/CD pipelines, and container registries for this purpose. The process begins with OpenTofu provisioning AWS infrastructure, including networking and an EKS cluster. GitLab CI/CD variables ensure secure and dynamic AWS configuration. A secondary pipeline automatically deploys essential Kubernetes tools like Argo CD and CertManager. Subsequently, a third pipeline deploys a sample web application using GitOps principles with Argo CD. This involves applying Argo CD application manifests to the cluster, enabling continuous synchronization. Before deployment, the web application is built, containerized, and pushed to the GitLab Container Registry. A dedicated CI/CD pipeline in the application repository automates this build and publishing process. This pipeline also updates deployment manifests in a separate repository, triggering Argo CD for automated application updates. The tutorial showcases how GitLab orchestrates the entire lifecycle, from infrastructure provisioning to application delivery, ensuring end-to-end automation.
