Behind the Curtain: Multi-Cluster Backstage Deployments with GitO...
summary
Pipeline shows end-to-end multicluster Backstage deployment where a merge to main builds an image, GitHub Actions submits an Argo workflow to rollout that tagged image across dev→prod clusters, and progressive health-checked rollouts gate promotion. Manifests are generated from Jsonnet + Tanka, infrastructure becomes Kubernetes CRDs managed by Crossplane for infra resources (replacing Terraform), and cluster reconciliation uses Flux v2 for GitOps to apply Kubernetes manifests.
