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.

BucketAccessSpec grants an RGW user a level of access to a Bucket by
|
|
maintaining a statement in the bucket's S3 policy. If UserRef is empty the
|
|
operator provisions a dedicated user for this grant and writes its keys into
|
|
a Secret; otherwise it grants an existing ObjectStoreUser.

userRef:

UserRef optionally names an existing ObjectStoreUser (in this namespace)

SecretName is ignored (that user already owns its own credential Secret).
