Options

--global-cluster-identifier (string)

The cluster identifier for the global cluster to modify. This parameter isn’t case-sensitive.

Constraints:

  • Must match the identifier of an existing global database cluster.

--new-global-cluster-identifier (string)

The new cluster identifier for the global database cluster. 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.
  • Can’t end with a hyphen or contain two consecutive hyphens.

Example: my-cluster2

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

Specifies whether to enable deletion protection for the global database cluster. The global database cluster can’t be deleted when deletion protection is enabled.

--engine-version (string)

The version number of the database engine to which you want to upgrade.

To list all of the available engine versions for aurora-mysql (for MySQL-based Aurora global databases), use the following command:

aws rds describe-db-engine-versions --engine aurora-mysql --query '*[]|[?SupportsGlobalDatabases == `true`].[EngineVersion]'

To list all of the available engine versions for aurora-postgresql (for PostgreSQL-based Aurora global databases), use the following command:

aws rds describe-db-engine-versions --engine aurora-postgresql --query '*[]|[?SupportsGlobalDatabases == `true`].[EngineVersion]'

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

Specifies whether to allow major version upgrades.

Constraints: Must be enabled if you specify a value for the EngineVersion parameter that’s a different major version than the global cluster’s current version.

If you upgrade the major version of a global database, the cluster and DB instance parameter groups are set to the default parameter groups for the new version. Apply any custom parameter groups after completing the upgrade.

--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.

--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 a global DB cluster

The following modify-global-cluster example enables deletion protection for an Aurora MySQL-compatible global DB cluster.

aws rds modify-global-cluster \
    --global-cluster-identifier myglobalcluster \
    --deletion-protection

Status -> (string)

The current status of the global cluster. Possible values are as follows:

  • pending – The service received a request to switch over or fail over the global cluster. The global cluster’s primary DB cluster and the specified secondary DB cluster are being verified before the operation starts.
  • failing-over – Aurora is promoting the chosen secondary Aurora DB cluster to become the new primary DB cluster to fail over the global cluster.
  • cancelling – The request to switch over or fail over the global cluster was cancelled and the primary Aurora DB cluster and the selected secondary Aurora DB cluster are returning to their previous states.
  • switching-over – This status covers the range of Aurora internal operations that take place during the switchover process, such as demoting the primary Aurora DB cluster, promoting the secondary Aurora DB cluster, and synchronizing replicas.
