list-instances¶
Description¶
Provides information for all active EC2 instances and EC2 instances terminated in the last 30 days, up to a maximum of 2,000. EC2 instances in any of the following states are considered active: AWAITING_FULFILLMENT, PROVISIONING, BOOTSTRAPPING, RUNNING.
See also: AWS API Documentation
See ‘aws help’ for descriptions of global parameters.
list-instances 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: Instances
Synopsis¶
list-instances
--cluster-id <value>
[--instance-group-id <value>]
[--instance-group-types <value>]
[--instance-fleet-id <value>]
[--instance-fleet-type <value>]
[--instance-states <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
Options¶
--cluster-id (string)
The identifier of the cluster for which to list the instances.
--instance-group-id (string)
The identifier of the instance group for which to list the instances.
--instance-group-types (list)
The type of instance group for which to list the instances.
(string)
Syntax:
"string" "string" ...
Where valid values are:
MASTER
CORE
TASK
--instance-fleet-id (string)
The unique identifier of the instance fleet.
--instance-fleet-type (string)
The node type of the instance fleet. For example MASTER, CORE, or TASK.
Possible values:
MASTER
CORE
TASK
--instance-states (list)
A list of instance states that will filter the instances returned with this request.
(string)
Syntax:
"string" "string" ...
Where valid values are:
AWAITING_FULFILLMENT
PROVISIONING
BOOTSTRAPPING
RUNNING
TERMINATED
--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
NextTokenfrom a previously truncated response.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
NextTokenis provided in the command’s output. To resume pagination, provide theNextTokenvalue in thestarting-tokenargument of a subsequent command. Do not use theNextTokenresponse 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¶
The following command lists all of the instances in a cluster with the cluster ID j-3C6XNQ39VR9WL:
aws emr list-instances --cluster-id j-3C6XNQ39VR9WL
