The operator previously assumed it created every user and bucket it managed:
reconciling an existing resource could overwrite its user attributes or wipe its
bucket policy, and deleting a CRD always deleted the underlying RGW object (only
Bucket had retainOnDelete). That made taking over pre-existing radosgw state
unsafe. Make adoption first-class.
- add retainOnDelete to ObjectStoreUser and BucketAccess (dedicated users), so
deleting the CRD orphans the RGW user instead of deleting it (symmetric with
Bucket)
- merge bucket policy instead of replacing it: the operator marks its own
statements with a cephrgwop* Sid and preserves any statement it does not own,
so adopting a bucket with a hand-written policy keeps it; add Bucket
managePolicy (default true) to opt out of policy management entirely
- only reconcile user attributes the spec sets: DisplayName when non-empty and
Suspended is now an optional *bool, so adopting a user does not reset them
- record adoption: ObjectStoreUser/Bucket status.adopted (+ printcolumn) is true
when the RGW object already existed on first reconcile
- add GetBucketPolicy + MergeBucketPolicy; keyed adoption detection off the
status identity field so a Pending owner wait does not mislabel it
- regenerate CRDs/deepcopy; add docs/adoption.md and
config/samples/05-adoption.yaml; cover the merge in policy_test.go

Adds a Kubernetes operator that provisions Ceph RGW (S3) buckets and
access keys declaratively through the Ceph manager dashboard REST API.
Three CRDs in group ceph.unkin.net/v1alpha1:
- ObjectStoreUser: creates an RGW user, delivers its key pair to a Secret
- Bucket: creates an S3 bucket owned by an ObjectStoreUser; owns the
bucket's aggregate S3 policy (union of all BucketAccess grants)
- BucketAccess: grants read-only/read-write/full access, provisioning a
dedicated user (or reusing a referenced one) and delivering RW/RO keys
The internal/ceph client wraps the dashboard /api/auth, /api/rgw/user and
/api/rgw/bucket endpoints with lazy token auth and re-auth on 401. Bucket
policies are rendered deterministically and applied via the bucket
policy API (Reef 18.2+). Credentials come from the cephrgw-credentials
Secret via env. Includes generated CRDs/RBAC, samples, kind manifests,
Woodpecker CI, and docs/ceph-setup.md covering the required Ceph
dashboard account, RGW wiring and permissions.
