The on-cluster cluster-vars ConfigMap wasn't reconciled by Flux — this bootstrap
model had no Kustomization watching clusters/dev, so cluster-vars/overlay changes
needed a manual 'kubectl apply -k clusters/dev' (e.g. DNS_ZONE substituted empty
until re-applied). Add clusters/dev/sync.yaml: a self-managing root Kustomization
(flux2 gotk-sync pattern, name flux-system) that reconciles ./clusters/dev from git
— cluster-vars, the GitRepository, platform/platform-config/apps, and itself. A git
push now suffices. Bootstrap unchanged ('kubectl apply -k clusters/dev' creates it
once). Verified: dev build contains all 6 objects (root + existing), prod unaffected.

# Self-managing ROOT Kustomization (the flux2 "gotk-sync" pattern).
|
|
#
|
|
# Reconciles ./clusters/dev from the GitRepository, so the ENTIRE graph is applied from git on every
|
|
# push: the cluster-vars ConfigMap, the GitRepository source, the platform / platform-config / apps
|
|
# Kustomizations — and THIS object itself. Without it the on-cluster cluster-vars ConfigMap was NOT
|
|
# reconciled by Flux, so overlay / cluster-vars changes needed a manual `kubectl apply -k clusters/dev`
|
|
# (DECISIONS-LOG F-OPS1). Now a `git push` is enough.
|
|
#
|
|
# Bootstrap is unchanged: `kubectl apply -k clusters/dev` (bootstrap/flux/bootstrap.sh step 3) still
|
|
# creates this once; thereafter it self-reconciles. prune keeps the cluster matching git; wait:false
|
|
# so the root never blocks on its children (platform has its own wait/health gating).
|
|
# NOTE: env-specific (path ./clusters/dev). A prod overlay needs its own sync.yaml → ./clusters/prod.
