Driving the Platform at Deutsche Bahn with Crossplanes Provider-Argocd
summary
Deutsche Bahn’s platform centers on Argo CD and Crossplane and runs in production for three years, managing over 50 Kubernetes clusters, supporting 50 developer teams and handling 10,000 managed resources across 100 Argo CD app projects and 180 repositories. A custom open‑source Kubernetes controller, provider-argocd, mirrors missing Argo CD HTTP API pieces into Crossplane to enable automated cluster registration from kubeconfig, encrypted credential handling, blueprint onboarding via compositions (54 compositions), Backstage scaffolds, and policy gating with OPA/Styra.
