Platform Engineering with the Argo Ecosystem: The Elastic Story
summary
Elastic builds a Kubernetes-first, multi-cloud platform that automates deploys to a growing fleet (they hit ~100 clusters and scale dynamically), using Crossplane to provision clusters and a custom Cluster Registration Controller to populate ArgoCD secrets so ApplicationSet can multiply Helm charts per cluster. Configuration uses Cue + Helm to generate strongly typed ArgoCD ApplicationSets and per-cluster values, onboarding via Backstage templates, and promotion uses Argo Events/Workflows plus a custom gpct (Get Ops Promotion Control) for gated, locked promotions and automated rollouts; the system is live and working.
