enable-availability-zones-for-load-balancer

Description

Adds the specified Availability Zones to the set of Availability Zones for the specified load balancer in EC2-Classic or a default VPC.

For load balancers in a non-default VPC, use AttachLoadBalancerToSubnets .

The load balancer evenly distributes requests across all its registered Availability Zones that contain instances. For more information, see Add or Remove Availability Zones in the Classic Load Balancers Guide .

Synopsis

  enable-availability-zones-for-load-balancer
--load-balancer-name <value>
--availability-zones <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--load-balancer-name (string)

The name of the load balancer.

--availability-zones (list)

The Availability Zones. These must be in the same region as the load balancer.

(string)

Syntax:

"string" "string" ...

--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.

See ‘aws help’ for descriptions of global parameters.
