[ aws . arc-zonal-shift ]

start-zonal-shift

Description

You start a zonal shift to temporarily move load balancer traffic away from an Availability Zone in an Amazon Web Services Region, to help your application recover immediately, for example, from a developer's bad code deployment or from an Amazon Web Services infrastructure failure in a single Availability Zone. You can start a zonal shift in Route 53 ARC only for managed resources in your Amazon Web Services account in an Amazon Web Services Region. Resources are automatically registered with Route 53 ARC by Amazon Web Services services.

At this time, you can only start a zonal shift for Network Load Balancers and Application Load Balancers with cross-zone load balancing turned off.

When you start a zonal shift, traffic for the resource is no longer routed to the Availability Zone. The zonal shift is created immediately in Route 53 ARC. However, it can take a short time, typically up to a few minutes, for existing, in-progress connections in the Availability Zone to complete.

For more information, see Zonal shift in the Amazon Route 53 Application Recovery Controller Developer Guide.

Options

--away-from (string)

The Availability Zone that traffic is moved away from for a resource when you start a zonal shift. Until the zonal shift expires or you cancel it, traffic for the resource is instead moved to other Availability Zones in the Amazon Web Services Region.

--comment (string)

A comment that you enter about the zonal shift. Only the latest comment is retained; no comment history is maintained. A new comment overwrites any existing comment string.

--expires-in (string)

The length of time that you want a zonal shift to be active, which Route 53 ARC converts to an expiry time (expiration time). Zonal shifts are temporary. You can set a zonal shift to be active initially for up to three days (72 hours).

If you want to still keep traffic away from an Availability Zone, you can update the zonal shift and set a new expiration. You can also cancel a zonal shift, before it expires, for example, if you're ready to restore traffic to the Availability Zone.

To set a length of time for a zonal shift to be active, specify a whole number, and then one of the following, with no space:

  • A lowercase letter m: To specify that the value is in minutes.
  • A lowercase letter h: To specify that the value is in hours.

For example: 20h means the zonal shift expires in 20 hours. 120m means the zonal shift expires in 120 minutes (2 hours).

--resource-identifier (string)

The identifier for the resource to shift away traffic for. The identifier is the Amazon Resource Name (ARN) for the resource.

At this time, supported resources are Network Load Balancers and Application Load Balancers with cross-zone load balancing turned off.

--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.

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

--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.

Output

awayFrom -> (string)

The Availability Zone that traffic is moved away from for a resource when you start a zonal shift. Until the zonal shift expires or you cancel it, traffic for the resource is instead moved to other Availability Zones in the Amazon Web Services Region.

comment -> (string)

A comment that you enter about the zonal shift. Only the latest comment is retained; no comment history is maintained. A new comment overwrites any existing comment string.

expiryTime -> (timestamp)

The expiry time (expiration time) for a customer-started zonal shift. A zonal shift is temporary and must be set to expire when you start the zonal shift. You can initially set a zonal shift to expire in a maximum of three days (72 hours). However, you can update a zonal shift to set a new expiration at any time.

When you start a zonal shift, you specify how long you want it to be active, which Route 53 ARC converts to an expiry time (expiration time). You can cancel a zonal shift when you're ready to restore traffic to the Availability Zone, or just wait for it to expire. Or you can update the zonal shift to specify another length of time to expire in.

resourceIdentifier -> (string)

The identifier for the resource to shift away traffic for. The identifier is the Amazon Resource Name (ARN) for the resource.

At this time, supported resources are Network Load Balancers and Application Load Balancers with cross-zone load balancing turned off.

startTime -> (timestamp)

The time (UTC) when the zonal shift starts.

status -> (string)

A status for a zonal shift.

The Status for a zonal shift can have one of the following values:

  • ACTIVE: The zonal shift has been started and active.
  • EXPIRED: The zonal shift has expired (the expiry time was exceeded).
  • CANCELED: The zonal shift was canceled.

zonalShiftId -> (string)

The identifier of a zonal shift.
