Parameters

This section describes some of the key AtlasDeployment custom resource parameters available. For a full list of available parameters for clusters, see the Atlas Clusters API and Atlas Advanced Clusters API. For a full list of available parameters for serverless instances, see the Atlas Serverless Instances API.

Refer to these descriptions, the available examples, and the API documentation to customize your specifications.

spec.advancedDeploymentSpec

Type: array

Conditional

List that contains the advanced cluster parameters from the API. For a full list of available parameters, see the Atlas Advanced Clusters API.

Important

You must specify spec.deploymentSpec, spec.advancedDeploymentSpec, or spec.serverlessSpec in your configuration.

spec.advancedDeploymentSpec.customZoneMapping

Type: array

Required

List that contains Global Cluster parameters that map zones to geographic regions. For a full list of available parameters, see the Atlas Global Clusters API.

spec.advancedDeploymentSpec.customZoneMapping.location

Type: string

Required

Code that represents a location that maps to a zone in your Global Cluster.

spec.advancedDeploymentSpec.customZoneMapping.zone

Type: string

Required

Human-readable label that identifies the zone in your Global Cluster.

spec.advancedDeploymentSpec.diskSizeGB

Type: number

Optional

Capacity, in gigabytes, that indicates the host's root volume. Increase this number to add capacity, up to a maximum possible value of 4096 (i.e., 4 TB). You must specify a positive number for this value.

You can't set this value with clusters with local NVMe SSDs.

Note

If you have autoscaling enabled for diskGB in any region, you can't edit this option. To learn more, see spec.advancedDeploymentSpec.replicationSpecs.regionConfigs.autoScaling.diskGB.enabled.

The minimum disk size for dedicated clusters is 10 GB for AWS and Google Cloud. If you specify this setting with a lower disk size, Atlas defaults to the minimum disk size value.

If your database deployment includes Azure nodes, this value must correspond to an existing Azure disk type (8, 16, 32, 64, 128, 256, 512, 1024, 2048, or 4096).

Atlas calculates storage charges differently depending on whether you choose the default value or a custom value.

Atlas has disk capacity limits on single replica sets, scaling up to 4 TB for higher cluster tiers. To expand the total cluster storage beyond default limits, you can enable extended storage in the Project Settings. To accommodate further scaling in the future, we recommend that you enable sharding for long-term expansion.

If your database deployment spans cloud service providers, this value defaults to the minimum default of the providers involved.

To learn more, see Storage Capacity.

spec.advancedDeploymentSpec.managedNamespaces

Type: array

Required

List that contains information to create a managed namespace in a specified Global Cluster to create. For a full list of available parameters, see the Atlas Global Clusters API.

Type: string

Required

Human-readable label of the database to manage in this Global Cluster.

spec.advancedDeploymentSpec.managedNamespaces.isCustomShardKeyHashed

Type: boolean

Optional

Flag that indicates whether to hash the custom shard key for the specified collection. This parameter defaults to false.

• Set to true to enable a custom shard key for the collection.

• Set to false to disable a custom shard key for the collection. If diabled, MongoDB uses ranged sharding.

To learn more, see Hashed Shard Keys.

spec.advancedDeploymentSpec.managedNamespaces.isCustomShardKeyUnique

Type: boolean

Optional

Flag that indicates whether the custom shard key for the specified collection is unique. This parameter defaults to false.

• Set to true to have MongoDB Cloud create and distribute initial chunks for an empty or non-existing collection.

• Set to false to not have MongoDB Cloud create and distribute initial chunks for an empty or non-existing collection..

spec.advancedDeploymentSpec.pitEnabled

Type: boolean

Conditional

Configuration that enables continuous cloud backup for advanced clusters. To enable continuous cloud backup, you must specify this setting with a value of true. For standard clusters see spec.deploymentSpec.pitEnabled.

spec.advancedDeploymentSpec.replicationSpecs.regionConfigs

Type: array

Required

Hardware specifications for nodes set for a given region. Each regionConfigs object describes the region's priority in elections and the number and type of MongoDB nodes that Atlas deploys to the region.

Each regionConfigs object must have either an analyticsSpecs object, electableSpecs object, or readOnlySpecs object.

• M0, M2, or M5` clusters require only ``electableSpecs.

• Dedicated clusters can specify any of these specifications, but must have at least one electableSpecs object within a replicationSpec.

• Every hardware specification must use the same instanceSize.

spec.advancedDeploymentSpec.replicationSpecs.regionConfigs.analyticsSpecs

Type: object

Optional

Hardware specifications for analytics nodes needed in the region. Analytics nodes handle analytic data such as reporting queries from BI Connector for Atlas. Analytics nodes are read-only and can never become the primary.

If you don't specify this parameter, Atlas deploys no analytics to this region.

spec.advancedDeploymentSpec.replicationSpecs.regionConfigs.autoScaling.diskGB.enabled

Type: boolean

Optional

Flag that indicates whether this database deployment enables disk auto-scaling. This parameter defaults to true.

• Set to true to enable disk auto-scaling.

• Set to false to disable disk auto-scaling.

The maximum amount of RAM for the selected cluster tier and the oplog size can limit storage auto-scaling. To learn more, see Customize Your Storage.

spec.advancedDeploymentSpec.replicationSpecs.regionConfigs.autoScaling.compute.enabled

Type: boolean

Optional

Flag that indicates whether instance size auto-scaling is enabled. This parameter defaults to false.

• Set to true to enable instance size auto-scaling. If enabled, you must specify a value for spec.advancedDeploymentSpec.replicationSpecs.regionConfigs.autoScaling.compute.maxInstanceSize.

• Set to false to disable instance size auto-scaling.

spec.advancedDeploymentSpec.replicationSpecs.regionConfigs.autoScaling.compute.maxInstanceSize

Type: string

Conditional

String that indicates the maximum instance size to which your database deployment can automatically scale (such as M40). You must specify this parameter if you set spec.advancedDeploymentSpec.replicationSpecs.regionConfigs.autoScaling.compute.enabled to true.

Note

If you set a maximum instance size smaller than the database deployment's current instance size with autoscaling enabled, Atlas automatically scales the current instance size to the maximum value you specify.

For example, if the database deployment's current instance size is M40 and you set the maximum instance size to M30, Atlas automatically scales the current instance size to M30.

If Atlas changes the current instance size and you don't change the spec.deploymentSpec.providerSettings.instanceSizeName in Atlas Kubernetes Operator to match the new instance size, Atlas Kubernetes Operator displays a warning in the logs but doesn't prevent autoscaling.

spec.advancedDeploymentSpec.replicationSpecs.regionConfigs.autoScaling.compute.minInstanceSize

Type: string

Conditional

String that indicates the minimum instance size to which your database deployment can automatically scale (such as M10). You must specify this parameter if you set spec.advancedDeploymentSpec.replicationSpecs.regionConfigs.autoScaling.compute.enabled to true.

Note

If you set a minimum instance size larger than the database deployment's current instance size with autoscaling enabled, Atlas automatically scales the current instance size to the minimum value you specify.

For example, if the database deployment's current instance size is M10 and you set the minimum instance size to M30, Atlas automatically scales the current instance size to M30.

If Atlas changes the current instance size and you don't change the spec.deploymentSpec.providerSettings.instanceSizeName in Atlas Kubernetes Operator to match the new instance size, Atlas Kubernetes Operator displays a warning in the logs but doesn't prevent autoscaling.

spec.advancedDeploymentSpec.replicationSpecs.regionConfigs.electableSpecs

Type: object

Optional

Hardware specifications for electable nodes in the region. Electable nodes can become the primary and can enable local reads.

If you don't specify this option, Atlas deploys no electable nodes to the region.

spec.advancedDeploymentSpec.replicationSpecs.regionConfigs.electableSpecs.instanceSize

Type: string

Conditional

Hardware specification for the instance sizes in this region. Each instance size has a default storage and memory capacity. The instance size you select applies to all the data-bearing hosts in your instance size. To learn more, see the AWS, GCP, and Azure custom storage sizes.

If you deploy a sharded cluster, or global cluster, you must choose an instance size of M30 or greater.

Note

If you have autoscaling enabled for the compute field, you can't edit this option. To learn more, see spec.advancedDeploymentSpec.replicationSpecs.regionConfigs.autoScaling.compute.enabled.

spec.advancedDeploymentSpec.replicationSpecs.regionConfigs.electableSpecs.nodeCount

Type: integer

Conditional

Number of electable nodes for Atlas to deploy to the region. Electable nodes can become the primary and can enable local reads.

The combined electableSpecs.nodeCount across all replicationSpecs.regionConfigs objects must total 3, 5, or 7.

You can't create electable nodes if spec.advancedDeploymentSpec.replicationSpecs.regionConfigs.priority is 0.

spec.advancedDeploymentSpec.replicationSpecs.regionConfigs.priority

Type: integer

Required

Precedence is given to this region when a primary election occurs.

If your regionConfigs has only readOnlySpecs, analyticsSpecs, or both, set this value to 0.

If you have multiple regionConfigs objects (your cluster is multi-region or multi-cloud), they must have priorities in descending order. The highest priority is 7.

Example

Set your highest priority region to 7, your second-highest priority to 6, and your third-priority region to 5. If you have no electable nodes, set this value to 0.

If your region has set electableSpecs.nodeCount to 1 or higher, it must have a priority of exactly one less than another region in the replicationSpecs.regionConfigs array unless it is the primary. The highest-priority region must have a priority of 7. The lowest possible priority is 1.

The priority 7 region identifies the Preferred Region of the cluster. Atlas places the primary node in the Preferred Region. Priorities 1 through 7 are exclusive: you can't assign a given priority to more than one region per cluster.

Example

If you have three regions, their priorities would be 7, 6, and 5 respectively. If you added two more regions for supporting electable nodes, the priorities of those regions would be 4 and 3 respectively.

spec.advancedDeploymentSpec.replicationSpecs.regionConfigs.readOnlySpecs

Type: object

Optional

Hardware specifications for read-only nodes in the region. Read-only nodes can never become the primary member, but can enable local reads.

If you don't specify this parameter, Atlas deploys no read-only nodes to the region.

Optional

List that contains the details for the AtlasBackupSchedule Custom Resource that you want to apply. You can specify one backup schedule per cluster.

spec.backupRef.name

Type: string

Optional

metadata.name value within the AtlasBackupSchedule Custom Resource for the backup schedule that you want to apply. You can specify only one backup schedule per cluster, but you can use the same backup schedule for multiple clusters.

If you don't specify this parameter, Atlas doesn't apply your backup configuration to this cluster.

spec.backupRef.namespace

Type: string

Optional

String that indicates the namespace that contains the AtlasBackupSchedule Custom Resource for the backup schedule that you want to apply.

spec.deploymentSpec

Type: array

Conditional

List that contains the cluster parameters from the API. For a full list of available parameters, see the Atlas Clusters API.

status.connectionStrings

Type: array

Required

List that contains the connection URLs for accessing the cluster. This parameter appears after you create or update a cluster.

Note

You can't use a connection URL directly. Atlas clusters require authentication. You must create at least one AtlasDatabaseUser Custom Resource before the application in your Kubernetes cluster can connect to the Atlas cluster. Atlas Kubernetes Operator creates a special secret for each cluster and database user combination in the project. The application in your Kubernetes cluster can use this secret to connect to the Atlas cluster. The spec.scopes parameter in the AtlasDatabaseUser custom resource restricts the clusters that create the database user.

For the configuration parameters available for a cluster and advanced cluster from the API, see the Atlas Clusters API, and Advanced Clusters API.
