Implemented KymaInstanceMapping CRD to enable mapping HANA Cloud instances to Kubernetes namespaces in both single-cluster and cross-cluster deployments. Key Features: - Extract HANA instance ID, admin API credentials, and cluster ID from Kyma cluster resources (ServiceInstance, ServiceBinding, ConfigMap) - Optional kymaConnectionRef for deployment flexibility: - Omit for single-cluster (uses local client) - Provide kubeconfig secret for cross-cluster access - Per-reconcile HANA Cloud client for credential isolation - Support BTP Service Operator resource patterns Architecture: - Controller reads ServiceInstance (instanceID), ServiceBinding (admin creds), and ConfigMap (clusterID) from target cluster - Creates instance mapping via HANA Cloud Admin API - Status tracks both Kyma resources and HANA Cloud mapping state - Never stores admin API credentials in ProviderConfig or CR status Changes: - New inventory.hana.orchestrate.cloud.sap/v1alpha1 API group - KymaInstanceMapping CRD with optional cross-cluster support - HANA Cloud Admin API client (OAuth2 + REST) - Remote cluster client for kubeconfig-based access - Instance mapping client for CRUD operations - Comprehensive documentation and examples for both patterns - ADR documenting architecture and data flow Examples: - examples/instancemapping/kymainstancemapping-local.yaml (single-cluster) - examples/instancemapping/kymainstancemapping-example.yaml (cross-cluster) - examples/instancemapping/KYMA_README.md (detailed guide) Documentation: - README.md updated with provider overview and installation guide - docs/ADR/20260218-kyma-instance-mapping-architecture.md Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> Signed-off-by: Maximilian Braun (SAP) <maximilian.braun@sap.com>
