Application Configuration Management at the Edge: Taming Thousands of Deployment Targets
summary
Proposes grouping edge sites into reusable profiles and producing per-app-per-profile OCI bundles so the registry holds only the installers each site needs; uses ytt, kbld, kapp and imgpkg to templatize/overlay YAML, resolve and lock image SHAs, package bundles (recursive bundles allowed), and apply them declaratively via a PackageRepository + PackageInstall CRD plus an App CRD for GitOps. Demonstrates image copying for air‑gapped registries that rewrites BOM locks and a schema (OpenAPI3) to expose configurable values.
