Options

--db-instance-identifier (string)

The DB instance identifier. This parameter 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

--db-instance-class (string)

The compute and memory capacity of the DB instance; for example, db.r5.large .

--engine (string)

The name of the database engine to be used for this instance.

Valid value: docdb

--availability-zone (string)

The Amazon EC2 Availability Zone that the DB instance is created in.

Default: A random, system-chosen Availability Zone in the endpoint's AWS Region.

Example: us-east-1d

Constraint: The AvailabilityZone parameter can't be specified if the MultiAZ parameter is set to true . The specified Availability Zone must be in the same AWS Region as the current endpoint.

--preferred-maintenance-window (string)

The time range each week during which system maintenance can occur, in Universal Coordinated Time (UTC).

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

The default is a 30-minute window selected at random from an 8-hour block of time for each AWS Region, occurring on a random day of the week.

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

Constraints: Minimum 30-minute window.

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

Indicates that minor engine upgrades are applied automatically to the DB instance during the maintenance window.

Default: true

--tags (list)

The tags to be assigned to the DB instance. You can assign up to 10 tags to an instance.

Shorthand Syntax:

Key=string,Value=string ...

JSON Syntax:

[
  {
    "Key": "string",
    "Value": "string"
  }
  ...
]

--db-cluster-identifier (string)

The identifier of the DB cluster that the instance will belong to.

--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 (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Examples

To create an Amazon DocumentDB cluster instance

The following create-db-instance example code creates the instance sample-cluster-instance-2 in the Amazon DocumentDB cluster sample-cluster.

aws docdb create-db-instance \
    --db-cluster-identifier sample-cluster \
    --db-instance-class db.r4.xlarge \
    --db-instance-identifier sample-cluster-instance-2 \
    --engine docdb
