AWS CLI Command Reference

[ aws . rds ]

promote-read-replica

Description

Promotes a read replica DB instance to a standalone DB instance.

Note

  • Backup duration is a function of the amount of changes to the database since the previous backup. If you plan to promote a read replica to a standalone instance, we recommend that you enable backups and complete at least one backup prior to promotion. In addition, a read replica cannot be promoted to a standalone instance when it is in the backing-up status. If you have enabled backups on your read replica, configure the automated backup window so that daily backups do not interfere with read replica promotion.

  • This command doesn’t apply to Aurora MySQL and Aurora PostgreSQL.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  promote-read-replica
--db-instance-identifier <value>
[--backup-retention-period <value>]
[--preferred-backup-window <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options

--db-instance-identifier (string)

The DB instance identifier. This value is stored as a lowercase string.

Constraints:

  • Must match the identifier of an existing read replica DB instance.

Example: mydbinstance

--backup-retention-period (integer)

The number of days for which automated backups are retained. Setting this parameter to a positive number enables backups. Setting this parameter to 0 disables automated backups.

Default: 1

Constraints:

  • Must be a value from 0 to 35.

  • Can’t be set to 0 if the DB instance is a source to read replicas.

--preferred-backup-window (string)

The daily time range during which automated backups are created if automated backups are enabled, using the BackupRetentionPeriod parameter.

The default is a 30-minute window selected at random from an 8-hour block of time for each AWS Region. To see the time blocks available, see Adjusting the Preferred Maintenance Window in the Amazon RDS User Guide.

Constraints:

  • Must be in the format hh24:mi-hh24:mi .

  • Must be in Universal Coordinated Time (UTC).

  • Must not conflict with the preferred maintenance window.

  • Must be at least 30 minutes.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.
