Add the storageclass dynamic-dropdown x-cozystack-options annotation to the storageClass field of the data apps (openbao, clickhouse, mariadb, redis, harbor, opensearch, rabbitmq, mongodb, postgres, nats, kafka, qdrant, foundationdb, http-cache) at the values.yaml source, so the extension is emitted by cozyvalues-gen instead of hand-edited into values.schema.json. kafka carries two (Kafka and ZooKeeper structs); foundationdb is nested under the Storage struct.

Managed NATS Service
NATS is an open-source, simple, secure, and high performance messaging system. It provides a data layer for cloud native applications, IoT messaging, and microservices architectures.
storageClassis annotated as immutable in the chart schema — seedocs/storage-immutability.mdfor the contract and which consumers enforce it.

Parameter examples and reference
resources and resourcesPreset
resources sets explicit CPU and memory configurations for each replica.
When left empty, the preset defined in resourcesPreset is applied.
resources:
cpu: 4000m
memory: 4Gi
resourcesPreset sets named CPU and memory configurations for each replica.
This setting is ignored if the corresponding resources value is set.
Presets follow a cloud-style <series>.<size> naming convention. Five series cover the full CPU-to-memory ratio range (t1 1:0.5, c1 1:1, s1 1:2, u1 1:4, m1 1:8) and each series ships eight sizes (nano through 4xlarge). The legacy flat names (nano, micro, small, medium, large, xlarge, 2xlarge) remain accepted as deprecated aliases of their 1:1 instance-type equivalents.
See docs/operations/resource-presets.md for the full size matrix and the legacy-to-instance-type mapping.
