From 37f4fa6767df73d34359ceff208ebc9f149d3d49 Mon Sep 17 00:00:00 2001 From: Keith Jackson Date: Mon, 24 Aug 2026 22:14:39 -0500 Subject: [PATCH 1/4] feat(updates): install Flux image controllers + cluster-wide write-back engine (R-UPD-02) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Install image-reflector-controller + image-automation-controller as part of the flux-system install (bootstrap.sh --components-extra) so the image.toolkit CRDs pre-exist before reconcile — no F-MON1 split needed for the ImageUpdateAutomation CR. Refine the cluster-wide ImageUpdateAutomation for machine-authored git write-back (setter strategy, path ./apps) reusing the flux-system GitRepository secretRef, and document the operator git-write-credential hand-off + SOPS secret template (gitea-image-automation-credentials). image-automation stays deferred in platform/kustomization.yaml until that credential is provisioned.
