Chapter 4. ClusterCSIDriver [operator.openshift.io/v1] Description ClusterCSIDriver object allows management and configuration of a CSI driver operator installed by default in OpenShift. Name of the object must be name of the CSI driver it operates. See CSIDriverName type for list of allowed values. Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer). Type object Required spec 4.1. Specification Property Type Description apiVersion string APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources kind string Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds metadata ObjectMeta Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata spec object spec holds user settable values for configuration status object status holds observed values from the cluster. They may not be overridden. 4.1.1. .spec Description spec holds user settable values for configuration Type object Property Type Description driverConfig object driverConfig can be used to specify platform specific driver configuration. When omitted, this means no opinion and the platform is left to choose reasonable defaults. These defaults are subject to change over time. logLevel string logLevel is an intent based logging for an overall component. It does not give fine grained control, but it is a simple way to manage coarse grained logging choices that operators have to interpret for their operands. Valid values are: "Normal", "Debug", "Trace", "TraceAll". Defaults to "Normal". managementState string managementState indicates whether and how the operator should manage the component observedConfig `` observedConfig holds a sparse config that controller has observed from the cluster state. It exists in spec because it is an input to the level for the operator operatorLogLevel string operatorLogLevel is an intent based logging for the operator itself. It does not give fine grained control, but it is a simple way to manage coarse grained logging choices that operators have to interpret for themselves. Valid values are: "Normal", "Debug", "Trace", "TraceAll". Defaults to "Normal". storageClassState string StorageClassState determines if CSI operator should create and manage storage classes. If this field value is empty or Managed - CSI operator will continuously reconcile storage class and create if necessary. If this field value is Unmanaged - CSI operator will not reconcile any previously created storage class. If this field value is Removed - CSI operator will delete the storage class it created previously. When omitted, this means the user has no opinion and the platform chooses a reasonable default, which is subject to change over time. The current default behaviour is Managed. unsupportedConfigOverrides `` unsupportedConfigOverrides overrides the final configuration that was computed by the operator. Red Hat does not support the use of this field. Misuse of this field could lead to unexpected behavior or conflict with other configuration options. Seek guidance from the Red Hat support before using this field. Use of this property blocks cluster upgrades, it must be removed before upgrading your cluster. 4.1.2. .spec.driverConfig Description driverConfig can be used to specify platform specific driver configuration. When omitted, this means no opinion and the platform is left to choose reasonable defaults. These defaults are subject to change over time. Type object Required driverType Property Type Description aws object aws is used to configure the AWS CSI driver. azure object azure is used to configure the Azure CSI driver. driverType string driverType indicates type of CSI driver for which the driverConfig is being applied to.

Consumers should treat unknown values as a NO-OP. gcp object gcp is used to configure the GCP CSI driver. ibmcloud object ibmcloud is used to configure the IBM Cloud CSI driver. vSphere object vsphere is used to configure the vsphere CSI driver. 4.1.3. .spec.driverConfig.aws Description aws is used to configure the AWS CSI driver. Type object Property Type Description efsVolumeMetrics object efsVolumeMetrics sets the configuration for collecting metrics from EFS volumes used by the EFS CSI Driver. kmsKeyARN string kmsKeyARN sets the cluster default storage class to encrypt volumes with a user-defined KMS key, rather than the default KMS key used by AWS. The value may be either the ARN or Alias ARN of a KMS key. 4.1.4. .spec.driverConfig.aws.efsVolumeMetrics Description efsVolumeMetrics sets the configuration for collecting metrics from EFS volumes used by the EFS CSI Driver. Type object Required state Property Type Description recursiveWalk object recursiveWalk provides additional configuration for collecting volume metrics in the AWS EFS CSI Driver when the state is set to RecursiveWalk. state string state defines the state of metric collection in the AWS EFS CSI Driver. This field is required and must be set to one of the following values: Disabled or RecursiveWalk. Disabled means no metrics collection will be performed. This is the default value. RecursiveWalk means the AWS EFS CSI Driver will recursively scan volumes to collect metrics. This process may result in high CPU and memory usage, depending on the volume size. 4.1.5. .spec.driverConfig.aws.efsVolumeMetrics.recursiveWalk Description recursiveWalk provides additional configuration for collecting volume metrics in the AWS EFS CSI Driver when the state is set to RecursiveWalk. Type object Property Type Description fsRateLimit integer fsRateLimit defines the rate limit, in goroutines per file system, for processing volume metrics. When omitted, this means no opinion and the platform is left to choose a reasonable default, which is subject to change over time. The current default is 5. The valid range is from 1 to 100 goroutines. refreshPeriodMinutes integer refreshPeriodMinutes specifies the frequency, in minutes, at which volume metrics are refreshed. When omitted, this means no opinion and the platform is left to choose a reasonable default, which is subject to change over time. The current default is 240. The valid range is from 1 to 43200 minutes (30 days). 4.1.6. .spec.driverConfig.azure Description azure is used to configure the Azure CSI driver. Type object Property Type Description diskEncryptionSet object diskEncryptionSet sets the cluster default storage class to encrypt volumes with a customer-managed encryption set, rather than the default platform-managed keys. 4.1.7. .spec.driverConfig.azure.diskEncryptionSet Description diskEncryptionSet sets the cluster default storage class to encrypt volumes with a customer-managed encryption set, rather than the default platform-managed keys. Type object Required name resourceGroup subscriptionID Property Type Description name string name is the name of the disk encryption set that will be set on the default storage class. The value should consist of only alphanumberic characters, underscores (_), hyphens, and be at most 80 characters in length. resourceGroup string resourceGroup defines the Azure resource group that contains the disk encryption set. The value should consist of only alphanumberic characters, underscores (_), parentheses, hyphens and periods.
