From the Ranch(er) to the Dev: A Case Study About Simplifying K8s Cluster Setup Wit...
summary
Automates Rancher cluster onboarding with Backstage and GitLab: a custom entity provider pulls clusters into the catalog, Backstage templates instantiate an infrastructure binder (Helm apps: Prometheus, Grafana, Kyverno, Sealed Secrets), a GitLab agent is installed via an in-cluster job to avoid stored tokens, and a sealing microservice generates sealed secrets so developers avoid extra CLIs. Process goes from 3 to 22 clusters, removes manual back-and-forth, and is currently running in production.
