Scaling Kubernetes across environments brings operational complexity, particularly when managing upgrades. Version-specific dependencies, deprecated APIs, and cluster drift all contribute to the challenge. In this talk, Reichert and Duarte draw on real-world experience to present practical strategies for structuring repositories to support scalable GitOps workflows. The session covers repository models such as MonoRepo (for all components or just add-ons) and repo-per-cluster, comparing their trade-offs in the context of upgrade management and environment consistency. Using tools like Flux v2, Kustomize, OpenTofu, and Helm, the speakers will demonstrate how a well-structured repository can simplify application and add-on deployments, manage environment-specific variables, and ensure consistent configuration across clusters. Attendees will leave with actionable insights into repository organization patterns that support scalable, secure, and maintainable GitOps practices for Kubernetes.
