A CloudFormation AWS::RDS::DBInstance.

The AWS::RDS::DBInstance resource creates an Amazon DB instance. The new DB instance can be an RDS DB instance, or it can be a DB instance in an Aurora DB cluster.

For more information about creating an RDS DB instance, see Creating an Amazon RDS DB instance in the Amazon RDS User Guide .

For more information about creating a DB instance in an Aurora DB cluster, see Creating an Amazon Aurora DB cluster in the Amazon Aurora User Guide .

If you import an existing DB instance, and the template configuration doesn't match the actual configuration of the DB instance, AWS CloudFormation applies the changes in the template during the import operation.

If a DB instance is deleted or replaced during an update, AWS CloudFormation deletes all automated snapshots. However, it retains manual DB snapshots. During an update that requires replacement, you can apply a stack policy to prevent DB instances from being replaced. For more information, see Prevent Updates to Stack Resources .

Updating DB instances

When properties labeled " Update requires: Replacement " are updated, AWS CloudFormation first creates a replacement DB instance, then changes references from other dependent resources to point to the replacement DB instance, and finally deletes the old DB instance.

We highly recommend that you take a snapshot of the database before updating the stack. If you don't, you lose the data when AWS CloudFormation replaces your DB instance. To preserve your data, perform the following procedure:

  • Deactivate any applications that are using the DB instance so that there's no activity on the DB instance.
  • Create a snapshot of the DB instance. For more information, see Creating a DB Snapshot .
  • If you want to restore your instance using a DB snapshot, modify the updated template with your DB instance changes and add the DBSnapshotIdentifier property with the ID of the DB snapshot that you want to use.

After you restore a DB instance with a DBSnapshotIdentifier property, you must specify the same DBSnapshotIdentifier property for any future updates to the DB instance. When you specify this property for an update, the DB instance is not restored from the DB snapshot again, and the data in the database is not changed. However, if you don't specify the DBSnapshotIdentifier property, an empty DB instance is created, and the original DB instance is deleted. If you specify a property that is different from the previous snapshot restore property, a new DB instance is restored from the specified DBSnapshotIdentifier property, and the original DB instance is deleted.

  • Update the stack.

For more information about updating other properties of this resource, see [ModifyDBInstance](https://docs.aws.amazon.com//AmazonRDS/latest/APIReference/API_ModifyDBInstance.html) . For more information about updating stacks, see AWS CloudFormation Stacks Updates .

Deleting DB instances

For DB instances that are part of an Aurora DB cluster, you can set a deletion policy for your DB instance to control how AWS CloudFormation handles the DB instance when the stack is deleted. For Amazon RDS DB instances, you can choose to retain the DB instance, to delete the DB instance, or to create a snapshot of the DB instance. The default AWS CloudFormation behavior depends on the DBClusterIdentifier property:

  • For AWS::RDS::DBInstance resources that don't specify the DBClusterIdentifier property, AWS CloudFormation saves a snapshot of the DB instance.
  • For AWS::RDS::DBInstance resources that do specify the DBClusterIdentifier property, AWS CloudFormation deletes the DB instance.

For more information, see DeletionPolicy Attribute .

      The name or Amazon Resource Name (ARN) of the DB snapshot that's used to restore the DB instance.

      If you're restoring from a shared manual DB snapshot, you must specify the ARN of the snapshot.

      By specifying this property, you can create a DB instance from the specified DB snapshot. If the DBSnapshotIdentifier property is an empty string or the AWS::RDS::DBInstance declaration has no DBSnapshotIdentifier property, AWS CloudFormation creates a new database. If the property contains a value (other than an empty string), AWS CloudFormation creates a database from the specified snapshot. If a snapshot with the specified name doesn't exist, AWS CloudFormation can't create the database and it rolls back the stack.

      Some DB instance properties aren't valid when you restore from a snapshot, such as the MasterUsername and MasterUserPassword properties. For information about the properties that you can specify, see the RestoreDBInstanceFromDBSnapshot action in the Amazon RDS API Reference .

      After you restore a DB instance with a DBSnapshotIdentifier property, you must specify the same DBSnapshotIdentifier property for any future updates to the DB instance. When you specify this property for an update, the DB instance is not restored from the DB snapshot again, and the data in the database is not changed. However, if you don't specify the DBSnapshotIdentifier property, an empty DB instance is created, and the original DB instance is deleted. If you specify a property that is different from the previous snapshot restore property, a new DB instance is restored from the specified DBSnapshotIdentifier property, and the original DB instance is deleted.

      If you specify the DBSnapshotIdentifier property to restore a DB instance (as opposed to specifying it for DB instance updates), then don't specify the following properties:

      For information about constraints that apply to DB instance identifiers, see Naming constraints in Amazon RDS in the Amazon RDS User Guide .

      The SourceDBInstanceIdentifier property determines whether a DB instance is a read replica. If you remove the SourceDBInstanceIdentifier property from your template and then update your stack, AWS CloudFormation promotes the Read Replica to a standalone DB instance.

      • If you specify a source DB instance that uses VPC security groups, we recommend that you specify the VPCSecurityGroups property. If you don't specify the property, the read replica inherits the value of the VPCSecurityGroups property from the source DB when you create the replica. However, if you update the stack, AWS CloudFormation reverts the replica's VPCSecurityGroups property to the default value because it's not defined in the stack's template. This change might cause unexpected issues.
      • Read replicas don't support deletion policies. AWS CloudFormation ignores any deletion policy that's associated with a read replica.
      • If you specify SourceDBInstanceIdentifier , don't specify the DBSnapshotIdentifier property. You can't create a read replica from a snapshot.
      • Don't set the BackupRetentionPeriod , DBName , MasterUsername , MasterUserPassword , and PreferredBackupWindow properties. The database attributes are inherited from the source DB instance, and backups are disabled for read replicas.

      @Stability(Stable) public void setUseLatestRestorableTime(@Nullable IResolvable value)
      A value that indicates whether the DB instance is restored from the latest backup time.

      By default, the DB instance isn't restored from the latest backup time.

      Constraints: Can't be specified if the RestoreTime parameter is provided.

    • getVpcSecurityGroups

      @Stability(Stable) @Nullable public List<String> getVpcSecurityGroups()
      A list of the VPC security group IDs to assign to the DB instance.

      The list can include both the physical IDs of existing VPC security groups and references to AWS::EC2::SecurityGroup resources created in the template.

      If you plan to update the resource, don't specify VPC security groups in a shared VPC.

      If you set VPCSecurityGroups , you must not set DBSecurityGroups , and vice versa.

      You can migrate a DB instance in your stack from an RDS DB security group to a VPC security group, but keep the following in mind:

      • You can't revert to using an RDS security group after you establish a VPC security group membership.
      • When you migrate your DB instance to VPC security groups, if your stack update rolls back because the DB instance update fails or because an update fails in another AWS CloudFormation resource, the rollback fails because it can't revert to an RDS security group.
      • To use the properties that are available when you use a VPC security group, you must recreate the DB instance. If you don't, AWS CloudFormation submits only the property values that are listed in the DBSecurityGroups property.

      To avoid this situation, migrate your DB instance to using VPC security groups only when that is the only change in your stack template.
