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.

This operation returns paginated results.

Creating a Request

listInstances #

Arguments

:: Text	`liClusterId`
-> ListInstances

Creates a value of ListInstances with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

liInstanceGroupTypes - The type of instance group for which to list the instances.
liInstanceFleetType - The node type of the instance fleet. For example MASTER, CORE, or TASK.
liMarker - The pagination token that indicates the next set of results to retrieve.
liInstanceFleetId - The unique identifier of the instance fleet.
liInstanceStates - A list of instance states that will filter the instances returned with this request.
liInstanceGroupId - The identifier of the instance group for which to list the instances.
liClusterId - The identifier of the cluster for which to list the instances.

data ListInstances #

This input determines which instances to list.

See: listInstances smart constructor.
