any-instance-in-service¶

Description¶

Wait until JMESPath query InstanceStates[].State returns InService for any element when polling with describe-instance-health. It will poll every 15 seconds until a successful state has been reached. This will exit with a return code of 255 after 40 failed checks.

Synopsis¶

  any-instance-in-service
--load-balancer-name <value>
[--instances <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--load-balancer-name (string)

The name of the load balancer.

--instances (list)

The IDs of the instances.

(structure)

The ID of an EC2 instance.

InstanceId -> (string)

The instance ID.

Shorthand Syntax:

InstanceId=string ...

JSON Syntax:

[
  {
    "InstanceId": "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.

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 pause running until any registered instance is in service

The following wait any-instance-in-service command pauses and continues only after it confirms that the specified load balancer has at least one instance in service.

aws elb wait any-instance-in-service
–load-balancer-name my-loadbalancer

This command produces no output.
