Convention: only the root app-of-apps (bootstrap) auto-syncs so it picks up
new/changed child Application definitions from Git. Every leaf service app
(metallb, metallb-config, envoy-gateway, envoy-gateway-config, nfs-provisioner)
now requires an explicit manual Sync — matches the existing argocd (self-manage)
and ignis convention.
Gateway API CRDs (httproutes, envoyproxies) have schemas large enough that
client-side apply's last-applied-configuration annotation exceeds the
262144-byte annotation limit. SSA skips that annotation entirely.
ArgoCD only builds a helm-pull command for oci:// sources when the repo is
registered with enableOCI: true; otherwise it falls back to classic --repo
handling, which errors on an oci:// URL. Registered via configs.repositories
in argocd's own values.yaml (Git-managed), Application source updated to
the bare host/path form ArgoCD expects for OCI repos.
