Addresses PR review + acceptance findings:
- Add leader-election RBAC: namespaced Role (coordination leases +
events) and RoleBinding to the operator ServiceAccount, so controllers
actually start under --leader-elect instead of looping on "leases
forbidden". Verified in a kind cluster: lease acquired, both
controllers start workers.
- Align Go versions: bump Dockerfile.operator to golang:1.26-alpine and
CI images to golang:1.26 to match go.mod (go 1.26.5); set
GOTOOLCHAIN=local so the image build stays hermetic (no toolchain
download).
- PVC controller: add an annotation predicate so only PVCs carrying (or
transitioning off of) backups.unkin.net/schedule enqueue, eliminating
reconcile churn from unannotated PVCs while keeping the teardown path.
- Cron validator: accept alphabetic month/day-of-week names (MON, JAN,
MON-FRI) that k8up and CNPG's robfig/cron accept, still rejecting
unknown names; add unit tests for both mapping paths.
- Deploy ordering: extract the Namespace into its own manifest and add a
config/kustomization.yaml so `kubectl apply -k config` creates the
namespace first; document it in the README.
- Note the credential-less push precedent (jellyfin-ha) in docker.yaml.
PVCs and CloudNativePG Clusters need S3 buckets and backup schedules
provisioned consistently. This operator watches the
backups.unkin.net/{schedule,destination} annotations on those objects and
provisions everything needed to back them up, with no new CRDs.
- Add a PVC controller that provisions cephrgw ObjectStoreUser/Bucket/BucketAccess,
auto-generates a restic repo-password Secret and creates a k8up Schedule scoped
to the PVC via spec.backup.volumes[].persistentVolumeClaim.claimName.
- Add a CNPG Cluster controller that provisions the same bucket stack, idempotently
patches spec.backup.barmanObjectStore (leaving a user-set destinationPath alone
with a Warning event) and creates a ScheduledBackup.
- Resolve destinations through a ConfigMap lookup table; requeue until the
BucketAccess is Ready before creating schedule resources; own-reference created
resources and retain bucket data by default.
- Add schedule-mapping helpers (k8up 5-field/shortcut pass-through, CNPG 6-field
seconds-first) and deterministic, length-bounded name derivation.
- Add unit tests (schedule mapping, name derivation, destination resolution) and
envtest controller tests for both paths, wiring the external CRDs into envtest.
- Add kubebuilder-generated RBAC, a Dockerfile (distroless/nonroot), Woodpecker
lint/test/build pipelines and a tag-triggered image push to the artifactapi
docker-internal registry, plus a version-bump Makefile and deploy manifests.
