Deleting a blue/green deployment - Amazon Aurora

Deleting a blue/green deployment

You can delete a blue/green deployment before or after you switch it over.

When you delete a blue/green deployment before switching it over, Amazon RDS optionally deletes the DB cluster in the green environment:

  • If you choose to delete the DB cluster in the green environment (--delete-target), it must have deletion protection turned off.

  • If you don't delete the DB cluster in the green environment (--no-delete-target), the cluster is retained, but it's no longer part of a blue/green deployment. For Aurora MySQL, replication continues between the environments. For Aurora PostgreSQL, the green environment is promoted to a standalone environment, so replication stops.

The option to delete the green databases isn't available in the console after switchover. When you delete blue/green deployments using the AWS CLI, you can't specify the --delete-target option if the deployment status is SWITCHOVER_COMPLETED.

Important

After you delete a blue/green deployment, RDS removes read-only protections from the previous production DB cluster. If the read_only parameter is disabled for the DB cluster, it starts to allow write operations again.

You can delete a blue/green deployment using the AWS Management Console, the AWS CLI, or the RDS API.

To delete a blue/green deployment

  1. Sign in to the AWS Management Console and open the Amazon RDS console at https://console.aws.amazon.com/rds/.

  2. In the navigation pane, choose Databases, and then choose the blue/green deployment that you want to delete.

  3. For Actions, choose Delete.

    The Delete Blue/Green Deployment? window appears.

    Delete blue/green deployment

    To delete the green databases, select Delete the green databases in this Blue/Green Deployment.

  4. Enter delete me in the box.

  5. Choose Delete.

To delete a blue/green deployment by using the AWS CLI, use the delete-blue-green-deployment command with the following options:

  • --blue-green-deployment-identifier – The resource ID of the blue/green deployment to be deleted.

  • --delete-target – Specifies that the DB cluster in the green environment is deleted. You can't specify this option if the blue/green deployment has a status of SWITCHOVER_COMPLETED.

  • --no-delete-target – Specifies that the DB cluster in the green environment is retained.

Example Delete a blue/green deployment and the DB cluster in the green environment

For Linux, macOS, or Unix:

aws rds delete-blue-green-deployment \
    --blue-green-deployment-identifier bgd-1234567890abcdef \
    --delete-target

For Windows:

aws rds delete-blue-green-deployment ^
    --blue-green-deployment-identifier bgd-1234567890abcdef ^
    --delete-target
Example Delete a blue/green deployment but retain the DB cluster in the green environment

For Linux, macOS, or Unix:

aws rds delete-blue-green-deployment \
    --blue-green-deployment-identifier bgd-1234567890abcdef \
    --no-delete-target

For Windows:

aws rds delete-blue-green-deployment ^
    --blue-green-deployment-identifier bgd-1234567890abcdef ^
    --no-delete-target

To delete a blue/green deployment by using the Amazon RDS API, use the DeleteBlueGreenDeployment operation with the following parameters:

  • BlueGreenDeploymentIdentifier – The resource ID of the blue/green deployment to be deleted.

  • DeleteTarget – Specify TRUE to delete the DB cluster in the green environment or FALSE to retain it. Cannot be TRUE if the blue/green deployment has a status of SWITCHOVER_COMPLETED.
