list-targets-by-rule

Description

Lists the targets assigned to the specified rule.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

list-targets-by-rule is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: Targets

Synopsis

  list-targets-by-rule
--rule <value>
[--event-bus-name <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--rule (string)

The name of the rule.

--event-bus-name (string)

The name or ARN of the event bus associated with the rule. If you omit this, the default event bus is used.

--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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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.

See ‘aws help’ for descriptions of global parameters.

Examples

To display all the targets for a CloudWatch Events rule

This example displays all the targets of the rule named DailyLambdaFunction:

aws events list-targets-by-rule --rule  "DailyLambdaFunction"

Output

Targets -> (list)

The targets assigned to the rule.

(structure)

Targets are the resources to be invoked when a rule is triggered. For a complete list of services and resources that can be set as a target, see PutTargets .

If you are setting the event bus of another account as the target, and that account granted permission to your account through an organization instead of directly by the account ID, then you must specify a RoleArn with proper permissions in the Target structure. For more information, see Sending and Receiving Events Between AWS Accounts in the Amazon EventBridge User Guide .

Id -> (string)

The ID of the target.

Arn -> (string)

The Amazon Resource Name (ARN) of the target.

RoleArn -> (string)

The Amazon Resource Name (ARN) of the IAM role to be used for this target when the rule is triggered. If one rule triggers multiple targets, you can use a different IAM role for each target.

Input -> (string)

Valid JSON text passed to the target. In this case, nothing from the event itself is passed to the target. For more information, see The JavaScript Object Notation (JSON) Data Interchange Format .

InputPath -> (string)

The value of the JSONPath that is used for extracting part of the matched event when passing it to the target. You must use JSON dot notation, not bracket notation. For more information about JSON paths, see JSONPath .

InputTransformer -> (structure)

Settings to enable you to provide custom input to a target based on certain event data. You can extract one or more key-value pairs from the event and then use that data to send customized input to the target.

InputPathsMap -> (map)

Map of JSON paths to be extracted from the event. You can then insert these in the template in InputTemplate to produce the output you want to be sent to the target.

InputPathsMap is an array key-value pairs, where each value is a valid JSON path. You can have as many as 10 key-value pairs. You must use JSON dot notation, not bracket notation.

The keys cannot start with “AWS.”

key -> (string)

value -> (string)

InputTemplate -> (string)

Input template where you specify placeholders that will be filled with the values of the keys from InputPathsMap to customize the data sent to the target. Enclose each InputPathsMaps value in brackets: <value > The InputTemplate must be valid JSON.

If InputTemplate is a JSON object (surrounded by curly braces), the following restrictions apply:

• The placeholder cannot be used as an object key.

• Object values cannot include quote marks.

The following example shows the syntax for using InputPathsMap and InputTemplate .

"InputTransformer":

{

"InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},

"InputTemplate": "<instance> is in state <status>"

}

To have the InputTemplate include quote marks within a JSON string, escape each quote marks with a slash, as in the following example:

"InputTransformer":

{

"InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},

"InputTemplate": "<instance> is in state \"<status>\""

}

KinesisParameters -> (structure)

The custom parameter you can use to control the shard assignment, when the target is a Kinesis data stream. If you do not include this parameter, the default is to use the eventId as the partition key.

PartitionKeyPath -> (string)

The JSON path to be extracted from the event and used as the partition key. For more information, see Amazon Kinesis Streams Key Concepts in the Amazon Kinesis Streams Developer Guide .

RunCommandParameters -> (structure)

Parameters used when you are using the rule to invoke Amazon EC2 Run Command.

RunCommandTargets -> (list)

Currently, we support including only one RunCommandTarget block, which specifies either an array of InstanceIds or a tag.

(structure)

Information about the EC2 instances that are to be sent the command, specified as key-value pairs. Each RunCommandTarget block can include only one key, but this key may specify multiple values.

Key -> (string)

Can be either tag: tag-key or InstanceIds .

Values -> (list)

If Key is tag: tag-key , Values is a list of tag values. If Key is InstanceIds , Values is a list of Amazon EC2 instance IDs.

(string)

EcsParameters -> (structure)

Contains the Amazon ECS task definition and task count to be used, if the event target is an Amazon ECS task. For more information about Amazon ECS tasks, see Task Definitions in the Amazon EC2 Container Service Developer Guide .

TaskDefinitionArn -> (string)

The ARN of the task definition to use if the event target is an Amazon ECS task.

TaskCount -> (integer)

The number of tasks to create based on TaskDefinition . The default is 1.

LaunchType -> (string)

Specifies the launch type on which your task is running. The launch type that you specify here must match one of the launch type (compatibilities) of the target task. The FARGATE value is supported only in the Regions where AWS Fargate with Amazon ECS is supported. For more information, see AWS Fargate on Amazon ECS in the Amazon Elastic Container Service Developer Guide .

NetworkConfiguration -> (structure)

Use this structure if the ECS task uses the awsvpc network mode. This structure specifies the VPC subnets and security groups associated with the task, and whether a public IP address is to be used. This structure is required if LaunchType is FARGATE because the awsvpc mode is required for Fargate tasks.

If you specify NetworkConfiguration when the target ECS task does not use the awsvpc network mode, the task fails.

awsvpcConfiguration -> (structure)

Use this structure to specify the VPC subnets and security groups for the task, and whether a public IP address is to be used. This structure is relevant only for ECS tasks that use the awsvpc network mode.

Subnets -> (list)

Specifies the subnets associated with the task. These subnets must all be in the same VPC. You can specify as many as 16 subnets.

(string)

SecurityGroups -> (list)

Specifies the security groups associated with the task. These security groups must all be in the same VPC. You can specify as many as five security groups. If you do not specify a security group, the default security group for the VPC is used.

(string)

AssignPublicIp -> (string)

Specifies whether the task’s elastic network interface receives a public IP address. You can specify ENABLED only when LaunchType in EcsParameters is set to FARGATE .

PlatformVersion -> (string)

Specifies the platform version for the task. Specify only the numeric portion of the platform version, such as 1.1.0 .

This structure is used only if LaunchType is FARGATE . For more information about valid platform versions, see AWS Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .

Group -> (string)

Specifies an ECS task group for the task. The maximum length is 255 characters.

BatchParameters -> (structure)

ArrayProperties -> (structure)

The array properties for the submitted job, such as the size of the array. The array size can be between 2 and 10,000. If you specify array properties for a job, it becomes an array job. This parameter is used only if the target is an AWS Batch job.

Size -> (integer)

The size of the array, if this is an array batch job. Valid values are integers between 2 and 10,000.

RetryStrategy -> (structure)

The retry strategy to use for failed jobs, if the target is an AWS Batch job. The retry strategy is the number of times to retry the failed job execution. Valid values are 1–10. When you specify a retry strategy here, it overrides the retry strategy defined in the job definition.
