modify-db-instance¶

Description¶

Modifies settings for an instance. You can change one or more database configuration parameters by specifying these parameters and the new values in the request.

Synopsis¶

  modify-db-instance
--db-instance-identifier <value>
[--db-instance-class <value>]
[--apply-immediately | --no-apply-immediately]
[--preferred-maintenance-window <value>]
[--auto-minor-version-upgrade | --no-auto-minor-version-upgrade]
[--new-db-instance-identifier <value>]
[--ca-certificate-identifier <value>]
[--promotion-tier <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options¶

--db-instance-identifier (string)

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

Constraints:

Must match the identifier of an existing DBInstance .

--db-instance-class (string)

The new compute and memory capacity of the instance; for example, db.r5.large . Not all instance classes are available in all AWS Regions.

If you modify the instance class, an outage occurs during the change. The change is applied during the next maintenance window, unless ApplyImmediately is specified as true for this request.

Default: Uses existing setting.

--apply-immediately | --no-apply-immediately (boolean)

Specifies whether the modifications in this request and any pending modifications are asynchronously applied as soon as possible, regardless of the PreferredMaintenanceWindow setting for the instance.

If this parameter is set to false , changes to the instance are applied during the next maintenance window. Some parameter changes can cause an outage and are applied on the next reboot.

Default: false

--preferred-maintenance-window (string)

The weekly time range (in UTC) during which system maintenance can occur, which might result in an outage. Changing this parameter doesn’t result in an outage except in the following situation, and the change is asynchronously applied as soon as possible. If there are pending actions that cause a reboot, and the maintenance window is changed to include the current time, changing this parameter causes a reboot of the instance. If you are moving this window to the current time, there must be at least 30 minutes between the current time and end of the window to ensure that pending changes are applied.

Default: Uses existing setting.

Format: ddd:hh24:mi-ddd:hh24:mi

Valid days: Mon, Tue, Wed, Thu, Fri, Sat, Sun

Constraints: Must be at least 30 minutes.

--auto-minor-version-upgrade | --no-auto-minor-version-upgrade (boolean)

Indicates that minor version upgrades are applied automatically to the instance during the maintenance window. Changing this parameter doesn’t result in an outage except in the following case, and the change is asynchronously applied as soon as possible. An outage results if this parameter is set to true during the maintenance window, and a newer minor version is available, and Amazon DocumentDB has enabled automatic patching for that engine version.

--new-db-instance-identifier (string)

The new instance identifier for the instance when renaming an instance. When you change the instance identifier, an instance reboot occurs immediately if you set Apply Immediately to true . It occurs during the next maintenance window if you set Apply Immediately to false . This value is stored as a lowercase string.

Constraints:

Must contain from 1 to 63 letters, numbers, or hyphens.

The first character must be a letter.

Cannot end with a hyphen or contain two consecutive hyphens.

Example: mydbinstance

--ca-certificate-identifier (string)

Indicates the certificate that needs to be associated with the instance.

--promotion-tier (integer)

A value that specifies the order in which an Amazon DocumentDB replica is promoted to the primary instance after a failure of the existing primary instance.

Default: 1

Valid values: 0-15

--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.

Examples¶

To modify an Amazon DocumentDB instance

The following modify-db-instance example modifies the Amazon DocumentDB instance sample-cluster2 by changing its instance class to db.r4.4xlarge and its promotion tier to 5. The changes are applied immediately but can only be seen after the instances status is available.

aws docdb modify-db-instance \
    --db-instance-identifier sample-cluster2 \
    --apply-immediately \
    --db-instance-class db.r4.4xlarge \
    --promotion-tier 5
