The operator drove the Ceph manager dashboard REST API to manage RGW users,
buckets and policies. That coupled it to a dashboard login, the dashboard's RGW
wiring, and the dashboard's bucket API surface. Rebuild the Ceph integration to
talk directly to radosgw the way the CLI does, using native Go libraries, while
keeping every operator capability identical.
The exported surface of internal/ceph is unchanged, so the three controllers
and cmd/operator's structure are untouched (bar the CEPH_RGW_* config plumbing).
- replace the internal/ceph client internals with github.com/ceph/go-ceph
rgw/admin (Admin Ops API) for users, keys, quotas and bucket info/removal
- add github.com/aws/aws-sdk-go-v2 S3 client for bucket create, versioning,
policy, tagging and object lock, signed as the bucket owner
- map go-ceph admin.ErrNoSuch*/ErrUserExists and smithy APIError codes into
IsNotFound/IsConflict so controller create-vs-update branching is preserved
- set S3 path-style addressing and WhenRequired checksum modes for RGW
- delete the hand-rolled dashboard client, token auth and JSON plumbing
- keep policy.go/BuildBucketPolicy/BuildTagJSON as pure builders
- replace the client tests with NewClient validation and error-classifier tests
- keep CGO_ENABLED=0 distroless: only go-ceph's pure-Go rgw/admin is imported
- switch env/config to CEPH_RGW_* (endpoint, admin endpoint, access/secret key,
region, CA, insecure) and update the deployment manifest
- rewrite README and docs/ceph-setup.md for the single RGW admin user
(caps users=*;buckets=*), keeping Vault/VSO as the primary credential source

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.
