Replicate Amazon Secrets Manager secrets across Regions

You can replicate your secrets in multiple Amazon Web Services Regions to support applications spread across those Regions to meet Regional access and low latency requirements. If you later need to, you can promote a replica secret to a standalone and then set it up for replication independently. Secrets Manager replicates the encrypted secret data and metadata such as tags and resource policies across the specified Regions.

The ARN for a replicated secret is the same as the primary secret except for the Region, for example:

  • Primary secret: arn:aws-cn:secretsmanager:Region1:123456789012:secret:MySecret-a1b2c3

  • Replica secret: arn:aws-cn:secretsmanager:Region2:123456789012:secret:MySecret-a1b2c3

For pricing information for replica secrets, see Amazon Secrets Manager Pricing.

When you store database credentials for a source database that is replicated to other Regions, the secret contains connection information for the source database. If you then replicate the secret, the replicas are copies of the source secret and contain the same connection information. You can add additional key/value pairs to the secret for regional connection information.

If you turn on rotation for your primary secret, Secrets Manager rotates the secret in the primary Region, and the new secret value propagates to all of the associated replica secrets. You don't have to manage rotation individually for all of the replica secrets.

You can replicate secrets across all of your enabled Amazon Regions. However, if you use Secrets Manager in special Amazon Regions such as Amazon GovCloud (US) or China Regions, you can only configure secrets and the replicas within these specialized Amazon Regions. You can't replicate a secret in your enabled Amazon Regions to a specialized Region or replicate secrets from a specialized region to a commercial region.

Before you can replicate a secret to another Region, you must enable that Region. For more information, see Managing Amazon Regions.

It is possible to use a secret across multiple Regions without replicating it by calling the Secrets Manager endpoint in the Region where the secret is stored. For a list of endpoints, see Amazon Secrets Manager endpoints. To use replication to improve your workload's resilience, see Disaster Recovery (DR) Architecture on Amazon, Part I: Strategies for Recovery in the Cloud.

Secrets Manager generates a CloudTrail log entry when you replicate a secret. For more information, see Log Amazon Secrets Manager events with Amazon CloudTrail.

To replicate a secret to other Regions (console)

  1. Open the Secrets Manager console at https://console.amazonaws.cn/secretsmanager/.

  2. From the list of secrets, choose your secret.

  3. On the secret details page, on the Replication tab, do one of the following:

    • If your secret is not replicated, choose Replicate secret.

    • If your secret is replicated, in the Replicate secret section, choose Add Region.

  4. In the Add replica regions dialog box, do the following:

    1. For Amazon Region, choose the Region you want to replicate the secret to.

    2. (Optional) For Encryption key, choose a KMS key to encrypt the secret with. The key must be in the replica Region.

    3. (Optional) To add another Region, choose Add more regions.

    4. Choose Replicate.

    You return to the secret details page. In the Replicate secret section, the Replication status shows for each Region.

Amazon CLI

Example Replicate a secret to another region

The following replicate-secret-to-regions example replicates a secret to eu-west-3. The replica is encrypted with the Amazon managed key aws/secretsmanager.

aws secretsmanager replicate-secret-to-regions \
        --secret-id MyTestSecret \
        --add-replica-regions Region=eu-west-3
Example Create a secret and replicate it

The following example creates a secret and replicates it to eu-west-3. The replica is encrypted with the Amazon managed key aws/secretsmanager.

aws secretsmanager create-secret \
    --name MyTestSecret \
    --description "My test secret created with the CLI." \
    --secret-string "{\"user\":\"diegor\",\"password\":\"EXAMPLE-PASSWORD\"}"
    --add-replica-regions Region=eu-west-3

Amazon SDK

To replicate a secret, use the ReplicateSecretToRegions command. For more information, see Amazon SDKs.
