Parameters

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

Important

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

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.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.

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.

spec.backupRef

Type: object

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 parameters available, see the Atlas Clusters API.

Important

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

spec.deploymentSpec.clusterType

Type: string

Conditional

Human-readable label that identifies cluster type to create.

When should you use this parameter?

Condition	Necessity
You set spec.deploymentSpec.replicationSpecs.	Required
You are deploying Global Clusters.	Required
You are deploying non-Global replica sets and sharded clusters.	Optional

Atlas accepts:

Value	Cluster Type
REPLICASET	replica set
SHARDED	sharded cluster
GEOSHARDED	global cluster

spec.deploymentSpec.mongoDBMajorVersion

Type: string

Optional

Version of the cluster to deploy. Atlas supports the following MongoDB versions for M10+ clusters:

• 4.2
• 4.4
• 5.0

The following conditions produce the following results:

Condition	Result
You omit this parameter and you omit the spec.deploymentSpec.versionReleaseSystem parameter.	Atlas deploys a cluster that runs MongoDB 5.0.
You omit this parameter and you set the spec.deploymentSpec.versionReleaseSystem parameter to LTS.	Atlas deploys a cluster that runs MongoDB 5.0.
You set the spec.deploymentSpec.providerSettings.instanceSizeName parameter to M0, M2, or M5.	You must deploy MongoDB 5.0.
You specify this parameter.	Atlas always deploys the cluster with the latest stable patch release of the specified version.
You set the spec.deploymentSpec.versionReleaseSystem parameter to CONTINUOUS.	You must omit this parameter.

spec.deploymentSpec.providerSettings

Type: Object

Conditional

Configuration that specifies the settings for the provisioned hosts on which MongoDB runs. The available options are specific to the cloud service provider. To learn more, see the AWS, GCP, and Azure cluster configuration options.

If you want to create or update a cluster, you must specify this setting.

spec.deploymentSpec.providerSettings.providerName

Type: string

Conditional

Cloud service provider on which Atlas provisions the hosts.

AWS	Amazon AWS
GCP	Google Cloud Platform
AZURE	Microsoft Azure

spec.deploymentSpec.providerSettings.instanceSizeName

Type: string

Required

Atlas provides different cluster tiers, each with a default storage capacity and RAM size. The cluster you select is used for all the data-bearing servers in your cluster. To learn more, see the AWS, GCP, and Azure custom storage sizes.

Note

You can change this setting to upgrade an M0, M2, or M5 cluster to an M10+ cluster. However, you can't upgrade an M0, M2, or M5 cluster to another free or shared cluster. For example, you can't upgrade an M0 cluster to an M5 cluster.

spec.deploymentSpec.providerSettings.regionName

Type: string

Conditional

Physical location of your MongoDB cluster. The region you choose can affect network latency for clients accessing your databases.

For a complete list of region name values, refer to the the cloud provider reference pages:

• AWS
• GCP
• Azure

For multi-region clusters, see spec.deploymentSpec.replicationSpecs. You must set either spec.deploymentSpec.providerSettings.regionName or spec.deploymentSpec.replicationSpecs.

spec.deploymentSpec.replicationSpecs

Type: array of objects

Conditional

List that contains the configurations for your cluster regions. Use this parameter for multi-region clusters. You must set either spec.deploymentSpec.providerSettings.regionName or spec.deploymentSpec.replicationSpecs.

When should you use this parameter?

Condition	Necessity	Values
You are deploying Global Clusters.	Required	Each object in the array represents a zone where Atlas deploys your cluster's nodes.
You are deploying non-Global replica sets and sharded clusters.	Optional	This array has one object representing where Atlas deploys your cluster's nodes.

If you specify this parameter, you must also specify spec.deploymentSpec.clusterType and spec.deploymentSpec.replicationSpecs.numShards.

spec.deploymentSpec.replicationSpecs.numShards

Type: integer

Conditional

Positive integer that specifies the number of shards to deploy for a sharded cluster.

If you use the spec.deploymentSpec.replicationSpecs parameter, you must set this parameter.

Atlas accepts 1 through 50, inclusive. The default value is 1.

• If you specify a value of 1 and you set spec.deploymentSpec.clusterType to SHARDED, Atlas deploys a single-shard sharded cluster.

• If you specify 1 and you set spec.deploymentSpec.clusterType to REPLICASET, Atlas deploys a replica set.

  Don't create a sharded cluster with a single shard for production environments. Single-shard sharded clusters don't provide the same benefits as multi-shard configurations.

  Tip

  See also:

  • Sharding
  • Number of Nodes

spec.deploymentSpec.replicationSpecs.zoneName

Type: string

Optional

Human-readable label that identifies the zone in a Global Cluster. Provide this value only if you set spec.deploymentSpec.clusterType to GEOSHARDED.

spec.deploymentSpec.versionReleaseSystem

Type: string

Conditional

Release cadence that Atlas uses for this cluster. Atlas accepts:

• CONTINUOUS: Atlas creates your cluster using the most recent MongoDB release. Atlas automatically updates your cluster to the latest major and rapid MongoDB releases as they become available.

• LTS: Atlas creates your cluster using the latest patch release of the MongoDB version that you specify in the spec.deploymentSpec.mongoDBMajorVersion parameter. Atlas automatically updates your cluster to subsequent patch releases of this MongoDB version. Atlas doesn't update your cluster to newer rapid or major MongoDB releases as they become available.

  If omitted, defaults to LTS.

  If you set this parameter to CONTINUOUS, you must omit the spec.deploymentSpec.mongoDBMajorVersion parameter.

spec.processArgs

Type: object

Optional

Object that contains the advanced configuration options for your cluster.

spec.processArgs.defaultReadConcern

Type: string

Optional

String that indicates the default level of acknowledgment requested from MongoDB for read operations set for this cluster.

MongoDB 5.0 clusters default to majority.

spec.processArgs.failIndexKeyTooLong

Type: boolean

Optional

Flag that indicates whether to fail the operation and return an error when you insert or update documents where all indexed entries exceed 1024 bytes. If you set this to false, mongod writes documents that exceed this limit, but doesn't index them.

This option corresponds to the failIndexKeyTooLong mongod parameter.

spec.processArgs.javascriptEnabled

Type: boolean

Optional

Flag that indicates whether the cluster allows execution of operations that perform server-side executions of JavaScript.

• If your cluster runs a MongoDB version less than 4.4, this option corresponds to modifying the security.javascriptEnabled configuration file option for each mongod in the cluster.
• If your cluster runs MongoDB version 4.4 or greater, this option corresponds to modifying the security.javascriptEnabled configuration file option for each mongod and mongos in the cluster.

spec.processArgs.minimumEnabledTlsProtocol

Type: integer

Optional

String that indicates the minimum TLS version that the cluster accepts for incoming connections. Clusters using TLS 1.0 or 1.1 should consider setting TLS 1.2 as the minimum TLS protocol version.

To learn more, see What versions of TLS does Atlas support?.

This option corresponds to the net.ssl.disabledProtocols mongod configuration file option.

spec.processArgs.noTableScan

Type: boolean

Optional

Flag that indicates whether the cluster disables executing any query that requires a collection scan to return results.

This option corresponds to the notablescan mongod parameter.

spec.processArgs.oplogSizeMB

Type: integer

Optional

Number that indicates the storage limit of a cluster's oplog expressed in megabytes. A value of null indicates that the cluster uses the default oplog size that Atlas calculates.

This option corresponds to the replication.oplogSizeMB mongod configuration file option.

spec.processArgs.sampleRefreshIntervalBIConnector

Type: integer

Optional

Number that indicates the documents per database to sample when gathering schema information.

This parameter corresponds to the sampleSize mongosqld option.

spec.processArgs.sampleSizeBIConnector

Type: integer

Optional

Number that indicates the interval in seconds at which the mongosqld process re-samples data to create its relational schema.

This parameter corresponds to the sampleRefreshIntervalSecs mongosqld option.

spec.projectRef.name

Type: string

Required

Name of the project where the cluster belongs. You must specify an existing AtlasProject Custom Resource.

spec.serverlessSpec

Type: array

Conditional

List that contains the serverless instance parameters from the API. For a full list of parameters available, see the Atlas Serverless Instances API.

Important

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

spec.serverlessSpec.providerSettings

Type: Object

Conditional

Configuration that specifies the settings for the provisioned hosts on which MongoDB runs. The available options are specific to the cloud service provider. To learn more, see the AWS, GCP, and Azure serverless instance configuration options.

If you want to create or update a serverless instance, you must specify this setting.

Type: string

Conditional

Physical location of your MongoDB serverless instance. The region you choose can affect network latency for clients accessing your databases.

For a complete list of region name values, refer to the the cloud provider reference pages:

• AWS
• GCP
• Azure

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.
