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: my-cluster2

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

A value that specifies whether the changes in this request and any pending changes are asynchronously applied as soon as possible, regardless of the PreferredMaintenanceWindow setting for the cluster. If this parameter is set to false , changes to the cluster are applied during the next maintenance window.

The ApplyImmediately parameter affects only the NewDBClusterIdentifier and MasterUserPassword values. If you set this parameter value to false , the changes to the NewDBClusterIdentifier and MasterUserPassword values are applied during the next maintenance window. All other changes are applied immediately, regardless of the value of the ApplyImmediately parameter.

Default: false

--backup-retention-period (integer)

The number of days for which automated backups are retained. You must specify a minimum value of 1.

Default: 1

Constraints:

Must be a value from 1 to 35.

--db-cluster-parameter-group-name (string)

The name of the cluster parameter group to use for the cluster.

--vpc-security-group-ids (list)

A list of virtual private cloud (VPC) security groups that the cluster will belong to.

(string)

Syntax:

"string" "string" ...

--port (integer)

The port number on which the cluster accepts connections.

Constraints: Must be a value from 1150 to 65535 .

Default: The same port as the original cluster.

--master-user-password (string)

The password for the master database user. This password can contain any printable ASCII character except forward slash (/), double quote (“), or the “at” symbol (@).

Constraints: Must contain from 8 to 100 characters.

--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 Amazon Web Services Region.

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.

--preferred-maintenance-window (string)

The weekly time range 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 Amazon Web Services Region, occurring on a random day of the week.

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

Constraints: Minimum 30-minute window.

--cloudwatch-logs-export-configuration (structure)

The configuration setting for the log types to be enabled for export to Amazon CloudWatch Logs for a specific instance or cluster. The EnableLogTypes and DisableLogTypes arrays determine which logs are exported (or not exported) to CloudWatch Logs.

EnableLogTypes -> (list)

The list of log types to enable.

(string)

DisableLogTypes -> (list)

The list of log types to disable.

(string)

Shorthand Syntax:

JSON Syntax:

{
  "EnableLogTypes": ["string", ...],
  "DisableLogTypes": ["string", ...]
}

--engine-version (string)

The version number of the database engine to which you want to upgrade. Changing this parameter results in an outage. The change is applied during the next maintenance window unless ApplyImmediately is enabled.

To list all of the available engine versions for Amazon DocumentDB use the following command:

aws docdb describe-db-engine-versions --engine docdb --query "DBEngineVersions[].EngineVersion"

--allow-major-version-upgrade | --no-allow-major-version-upgrade (boolean)

A value that indicates whether major version upgrades are allowed.

Constraints: You must allow major version upgrades when specifying a value for the EngineVersion parameter that is a different major version than the DB cluster’s current version.

--deletion-protection | --no-deletion-protection (boolean)

Specifies whether this cluster can be deleted. If DeletionProtection is enabled, the cluster cannot be deleted unless it is modified and DeletionProtection is disabled. DeletionProtection protects clusters from being accidentally deleted.

--storage-type (string)

The storage type to associate with the DB cluster.

For information on storage types for Amazon DocumentDB clusters, see Cluster storage configurations in the Amazon DocumentDB Developer Guide .

Valid values for storage type - standard | iopt1

Default value is standard

--manage-master-user-password | --no-manage-master-user-password (boolean)

Specifies whether to manage the master user password with Amazon Web Services Secrets Manager. If the cluster doesn’t manage the master user password with Amazon Web Services Secrets Manager, you can turn on this management. In this case, you can’t specify MasterUserPassword . If the cluster already manages the master user password with Amazon Web Services Secrets Manager, and you specify that the master user password is not managed with Amazon Web Services Secrets Manager, then you must specify MasterUserPassword . In this case, Amazon DocumentDB deletes the secret and uses the new password for the master user specified by MasterUserPassword .

--master-user-secret-kms-key-id (string)

The Amazon Web Services KMS key identifier to encrypt a secret that is automatically generated and managed in Amazon Web Services Secrets Manager.

This setting is valid only if both of the following conditions are met:

The cluster doesn’t manage the master user password in Amazon Web Services Secrets Manager. If the cluster already manages the master user password in Amazon Web Services Secrets Manager, you can’t change the KMS key that is used to encrypt the secret.

You are enabling ManageMasterUserPassword to manage the master user password in Amazon Web Services Secrets Manager. If you are turning on ManageMasterUserPassword and don’t specify MasterUserSecretKmsKeyId , then the aws/secretsmanager KMS key is used to encrypt the secret. If the secret is in a different Amazon Web Services account, then you can’t use the aws/secretsmanager KMS key to encrypt the secret, and you must use a customer managed KMS key.

The Amazon Web Services KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the KMS key. To use a KMS key in a different Amazon Web Services account, specify the key ARN or alias ARN.

There is a default KMS key for your Amazon Web Services account. Your Amazon Web Services account has a different default KMS key for each Amazon Web Services Region.

--rotate-master-user-password | --no-rotate-master-user-password (boolean)

Specifies whether to rotate the secret managed by Amazon Web Services Secrets Manager for the master user password.

This setting is valid only if the master user password is managed by Amazon DocumentDB in Amazon Web Services Secrets Manager for the cluster. The secret value contains the updated password.

Constraint: You must apply the change immediately when rotating the master user password.

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options¶

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

json
text
table
yaml
yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

on
off
auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

base64
raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To modify an Amazon DocumentDB cluster

The following modify-db-cluster example modifies the Amazon DocumentDB cluster sample-cluster by making the retention period for automatic backups 7 days, and changing the preferred windows for both backups and maintenance. All changes are applied at the next maintenance window.

aws docdb modify-db-cluster \
    --db-cluster-identifier sample-cluster \
    --no-apply-immediately \
    --backup-retention-period 7 \
    --preferred-backup-window 18:00-18:30 \
    --preferred-maintenance-window sun:20:00-sun:20:30
