Aruba Components

Reference for every Aruba Cloud offer in the Fractal Cloud catalogue. Parameters and their required flags are sourced from the agent param contract (FRA-2955); each offer includes a fully-parameterized JSON example.

BigData

BigData.PaaS.SparkPlatform

A Fractal-managed Spark platform that satisfies the abstract distributed-data-processing blueprint by installing the kubeflow spark-operator Helm release onto the first Aruba KaaS cluster discovered in the LiveSystem. Aruba has no native managed Spark, so this offer runs the operator on Kubernetes.

Parameter	Description	Example / possible values	Required
namespace	Kubernetes namespace where the Spark Operator is installed	spark-operator	No
webhookEnabled	Enable the Spark Operator's mutating/validating webhook	true	No

Example (fully parameterized):

{
  "type": "BigData.PaaS.SparkPlatform",
  "parameters": {
    "namespace": "spark-operator",
    "webhookEnabled": true
  }
}

BigData.PaaS.SparkPlatformCluster

Registers a Spark cluster spec (driver/executor sizing and base image) that downstream Spark jobs consume when they materialize a SparkApplication CR. The cluster itself does not create a long-running Kubernetes resource — the spec is purely metadata for jobs.

Parameter	Description	Example / possible values	Required
driverCores	CPU cores for the Spark driver pod	1	No
driverMemory	Memory for the Spark driver pod	1g	No
executorCores	CPU cores per executor pod	1	No
executorMemory	Memory per executor pod	1g	No
executorInstances	Number of executor pods	2	No
image	Container image URI for Spark pods	apache/spark:3.5.0	No
namespace	Kubernetes namespace where Spark jobs run	spark	No

Example (fully parameterized):

{
  "type": "BigData.PaaS.SparkPlatformCluster",
  "parameters": {
    "driverCores": "1",
    "driverMemory": "1g",
    "executorCores": "1",
    "executorMemory": "1g",
    "executorInstances": 2,
    "image": "apache/spark:3.5.0",
    "namespace": "spark"
  }
}

BigData.PaaS.SparkPlatformJob

Applies a ScheduledSparkApplication (when a cron schedule is set) or a one-shot SparkApplication CR to the Spark platform. Inherits driver/executor sizing from the linked Spark cluster spec; supports a JAR/Scala path and a Python wheel path (the agent wraps the wheel into an OCI image via kaniko when artifactUri is supplied).

Parameter	Description	Example / possible values	Required
namespace	Kubernetes namespace for the Spark application	spark	No
schedule	Cron expression for periodic execution; blank runs the job once	0 0 * * *	No
jarUri	URI to the application JAR (Scala/Java path)	local:///opt/spark/examples/jars/app.jar	No
mainClass	Fully qualified main class for the JAR path	org.apache.spark.examples.SparkPi	No
image	Container image URI for the Spark application	apache/spark:3.5.0	No

Example (fully parameterized):

{
  "type": "BigData.PaaS.SparkPlatformJob",
  "parameters": {
    "namespace": "spark",
    "schedule": "",
    "jarUri": "",
    "mainClass": "",
    "image": "apache/spark:3.5.0"
  }
}

BigData.PaaS.SparkPlatformMlExperiment

A Fractal-managed MLflow tracking service that satisfies the abstract ML-experiment blueprint by installing the mlflow Helm release onto the KaaS cluster. When a MinIO datalake is in the dependency chain, the agent automatically wires its S3 endpoint and admin credentials into MLflow for artifact storage.

Parameter	Description	Example / possible values	Required
namespace	Kubernetes namespace where MLflow is installed	mlflow	No
trackingUri	MLflow tracking URI; defaults to the in-cluster service URL	http://mlflow.mlflow.svc.cluster.local:5000	No
artifactRoot	Default artifact root for the MLflow server	s3://datalake/mlflow	No

Example (fully parameterized):

{
  "type": "BigData.PaaS.SparkPlatformMlExperiment",
  "parameters": {
    "namespace": "mlflow",
    "trackingUri": "",
    "artifactRoot": ""
  }
}

Messaging

Messaging.PaaS.ManagedKafka

A Fractal-managed Kafka broker that satisfies the abstract messaging-broker blueprint. Aruba has no native managed Kafka, so the agent installs the strimzi-kafka-operator (one per cluster) and applies a Kafka + KafkaNodePool CR pair in KRaft mode (single broker) onto the KaaS cluster.

Parameter	Description	Example / possible values	Required
namespace	Kubernetes namespace for the Kafka cluster	kafka	No
clusterName	Name of the Strimzi Kafka cluster; defaults to a sanitized component ID	events-broker	No

  "parameters": {
    "namespace": "kafka",
    "clusterName": ""
  }
}

Messaging.PaaS.ManagedKafkaTopic

A Strimzi KafkaTopic CR scoped to the linked managed Kafka cluster. The topic name is derived from the component ID; retention defaults to 7 days.

Parameter	Description	Example / possible values	Required
namespace	Kubernetes namespace; defaults to the linked cluster's namespace	kafka	No
partitions	Number of topic partitions	1	No
replicas	Topic replication factor	1	No

Example (fully parameterized):

{
  "type": "Messaging.PaaS.ManagedKafkaTopic",
  "parameters": {
    "namespace": "kafka",
    "partitions": 1,
    "replicas": 1
  }
}

    "subnetCidr": "192.168.0.0/16"
  }
}

NetworkAndCompute.PaaS.ArubaContainerRegistry

An Aruba managed container registry. Deferred to v2 — the SDK model currently exposes no endpoint/hostname field, so this offer is not yet wired into the image-prefixing flow.

Storage.PaaS.ArubaObjectStorageAccount

An Aruba S3-compatible Object Storage account. Stubbed (NotImplemented) — the offer is registered in the catalogue but disabled pending confirmation of the Aruba legacy provisioning endpoint. The canonical data-lake offer for Aruba is Storage.PaaS.ManagedDatalake (MinIO on KaaS). The legacy Object Storage API has no resource-tag support, so Fractal ownership semantics cannot be enforced on it.

Parameter	Description	Example / possible values	Required
accountName	Object Storage account name; defaults to a sanitized component ID	fct-datastore	No
password	Account password (min 9 chars, upper + lower + digit)	Sup3rSecret!	Yes
