CreateBlueGreenDeployment

Creates a blue/green deployment.

A blue/green deployment creates a staging environment that copies the production environment. In a blue/green deployment, the blue environment is the current production environment. The green environment is the staging environment, and it stays in sync with the current production environment.

You can make changes to the databases in the green environment without affecting production workloads. For example, you can upgrade the major or minor DB engine version, change database parameters, or make schema changes in the staging environment. You can thoroughly test changes in the green environment. When ready, you can switch over the environments to promote the green environment to be the new production environment. The switchover typically takes under a minute.

For more information, see Using Amazon RDS Blue/Green Deployments for database updates in the Amazon RDS User Guide and Using Amazon RDS Blue/Green Deployments for database updates in the Amazon Aurora User Guide.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

BlueGreenDeploymentName

The name of the blue/green deployment.

Constraints:

Can't be the same as an existing blue/green deployment name in the same account and AWS Region.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 60.

Pattern: [a-zA-Z](?:-?[a-zA-Z0-9]+)*

Required: Yes

Source

The Amazon Resource Name (ARN) of the source production database.

Specify the database that you want to clone. The blue/green deployment creates this database in the green environment. You can make updates to the database in the green environment, such as an engine version upgrade. When you are ready, you can switch the database in the green environment to be the production database.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 2048.

Pattern: arn:[A-Za-z][0-9A-Za-z-:._]*

Required: Yes

Tags.Tag.N

Tags to assign to the blue/green deployment.

Type: Array of Tag objects

Required: No

TargetAllocatedStorage

The amount of storage in gibibytes (GiB) to allocate for the green DB instance. You can choose to increase or decrease the allocated storage on the green DB instance.

This setting doesn't apply to Amazon Aurora blue/green deployments.

Type: Integer

Required: No

TargetDBClusterParameterGroupName

The DB cluster parameter group associated with the Aurora DB cluster in the green environment.

To test parameter changes, specify a DB cluster parameter group that is different from the one associated with the source DB cluster.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 255.

Pattern: [A-Za-z](?!.*--)[0-9A-Za-z-]*[^-]|^default(?!.*--)(?!.*\.\.)[0-9A-Za-z-.]*[^-]

Required: No

TargetDBInstanceClass

Specify the DB instance class for the databases in the green environment.

This parameter only applies to RDS DB instances, because DB instances within an Aurora DB cluster can have multiple different instance classes. If you're creating a blue/green deployment from an Aurora DB cluster, don't specify this parameter. After the green environment is created, you can individually modify the instance classes of the DB instances within the green DB cluster.

Type: String

Length Constraints: Minimum length of 5. Maximum length of 20.

Pattern: db\.[0-9a-z]{2,6}\.[0-9a-z]{4,9}

Required: No

TargetDBParameterGroupName

The DB parameter group associated with the DB instance in the green environment.

To test parameter changes, specify a DB parameter group that is different from the one associated with the source DB instance.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 255.

Pattern: [A-Za-z](?!.*--)[0-9A-Za-z-]*[^-]|^default(?!.*--)(?!.*\.\.)[0-9A-Za-z-.]*[^-]

Required: No

TargetEngineVersion

The engine version of the database in the green environment.

Specify the engine version to upgrade to in the green environment.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

Pattern: [0-9A-Za-z-_.]+

Required: No

TargetIops

The amount of Provisioned IOPS (input/output operations per second) to allocate for the green DB instance. For information about valid IOPS values, see Amazon RDS DB instance storage in the Amazon RDS User Guide.

This setting doesn't apply to Amazon Aurora blue/green deployments.

Type: Integer

Required: No

TargetResourceConfigurations.TargetResourceConfiguration.N

Specifies resource-level configuration overrides for the green environment.

Each entry identifies a resource in the blue environment by its Amazon Resource Name (ARN). It defines the desired configuration for the corresponding resource in the green environment. Any resource that you don't include in this parameter retains the same configuration as its counterpart in the blue environment.

Use this parameter when one or more resources in the green environment require a different configuration than what they have in the blue environment.

Constraints:

You can't specify the same SourceArn in more than one entry.

Type: Array of TargetResourceConfiguration objects

Array Members: Minimum number of 0 items. Maximum number of 20 items.

Required: No

TargetStorageThroughput

The storage throughput value for the green DB instance.

This setting applies only to the gp3 storage type.

This setting doesn't apply to Amazon Aurora blue/green deployments.

Type: Integer

Required: No

TargetStorageType

The storage type to associate with the green DB instance.

Valid Values: gp2 | gp3 | io1 | io2

This setting doesn't apply to Amazon Aurora blue/green deployments.

Type: String

Required: No

UpgradeTargetStorageConfig

Whether to upgrade the storage file system configuration on the green database. This option migrates the green DB instance from the older 32-bit file system to the preferred configuration. For more information, see Upgrading the storage file system for a DB instance.

Type: Boolean

Required: No

Response Elements

The following element is returned by the service.

BlueGreenDeployment
