0.2.0

Redkey Operator v0.2.0

This release delivers a major architectural refactoring of the Redkey system and
renames the project to redkey-operator. Responsibilities between the Operator
and Robin have been inverted: the Operator becomes a lightweight umbrella
coordinator, while Redkey Robin takes over all cluster and Kubernetes resource
management. Inter-component communication is now fully Kubernetes-native and
declarative — Robin's HTTP/REST API has been removed.

Highlights

• Operator as umbrella coordinator. The Operator no longer manages Redis
  resources directly. It focuses on coordination and housekeeping.
• New RedkeyConfig CRD. An intermediate, sequenced configuration resource
  replaces the previous in-process/REST coordination between components.
• Declarative, sequenced configuration. Each change to a Redkey produces a
  new immutable RedkeyConfig that Robin applies in order.
• Clean ownership boundary. The Operator writes RedkeyConfig.spec; Robin
  writes only RedkeyConfig.status. Enforced natively via the status subresource
  and tightened RBAC.

Architecture changes

• RedkeyConfig (redkey.inditex.dev/v1beta1). The Operator maintains a
  monotonic sequence counter and creates one RedkeyConfig per change, named
  <cluster>-<sequence>. Configs move through Pending → InProgress → Applied.
• Umbrella coordinator responsibilities:
  • Ensures the Robin Deployment exists and matches spec.robin (recreates or
    rolls it out on drift; pod/template and Robin config overrides preserved).
  • Aggregates a simplified, user-facing status onto Redkey.status
    (phase + conditions) from the highest-sequence RedkeyConfig.
  • Cleans up superseded Applied configs, keeping the namespace tidy.
  • Event-driven watch on Redkey plus a periodic safety-net loop.
• skipIfSuperseded. Optional fast-path to bypass intermediate pending
  configs when only the latest target matters (e.g. consecutive scale changes).
• RBAC tightened. Operator gets get/list/watch/create/delete on RedkeyConfig
  but not update/patch on its status; Robin gets read + status-only writes.

Packaging & tooling

• Multi-arch images (linux/amd64, linux/arm64) published to
  ghcr.io/inditextech/redkey-operator, tagged with the version and :latest.
• OLM bundle and catalog images published alongside the operator image.
• Helm chart CRDs are now generated from config/crd/bases via make sync-crds
  (invoked from make manifests), keeping chart and config CRDs in sync.
• Chart/docs default the deployment image tag to :latest.

Breaking changes

• Go module path is now github.com/inditextech/redkey-operator. Consumers of
  the API package (api/v1beta1) must update their import paths.
• Robin's HTTP/REST API is removed. All coordination is via the RedkeyConfig
  CRD; any integration relying on Robin's REST endpoints must migrate.
