create_blue_green_deployment#

RDS.Client.create_blue_green_deployment(**kwargs)#

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. The staging environment stays in sync with the current production environment using logical replication.

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 Syntax

response = client.create_blue_green_deployment(
    BlueGreenDeploymentName='string',
    Source='string',
    TargetEngineVersion='string',
    TargetDBParameterGroupName='string',
    TargetDBClusterParameterGroupName='string',
    Tags=[
        {
            'Key': 'string',

        },
    ]
)

Parameters:

BlueGreenDeploymentName (string) –
[REQUIRED]

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 Amazon Web Services Region.
Source (string) –
[REQUIRED]

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.
TargetEngineVersion (string) –
The engine version of the database in the green environment.

Specify the engine version to upgrade to in the green environment.
TargetDBParameterGroupName (string) –
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.
TargetDBClusterParameterGroupName (string) –
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.
Tags (list) –
Tags to assign to the blue/green deployment.
- (dict) –
  
  Metadata assigned to an Amazon RDS resource consisting of a key-value pair.
  
  For more information, see Tagging Amazon RDS Resources in the Amazon RDS User Guide.
  - Key (string) –
    
    A key is the required name of the tag. The string value can be from 1 to 128 Unicode characters in length and can’t be prefixed with aws: or rds:. The string can only contain only the set of Unicode letters, digits, white-space, ‘_’, ‘.’, ‘:’, ‘/’, ‘=’, ‘+’, ‘-’, ‘@’ (Java regex: “^([\p{L}\p{Z}\p{N}_.:/=+\-@]*)$”).
  - Value (string) –
    
    A value is the optional value of the tag. The string value can be from 1 to 256 Unicode characters in length and can’t be prefixed with aws: or rds:. The string can only contain only the set of Unicode letters, digits, white-space, ‘_’, ‘.’, ‘:’, ‘/’, ‘=’, ‘+’, ‘-’, ‘@’ (Java regex: “^([\p{L}\p{Z}\p{N}_.:/=+\-@]*)$”).

Return type:
