    • reservation-id - The ID of the instance's reservation. A reservation ID is created any time you launch an instance. A reservation ID has a one-to-one relationship with an instance launch request, but can be associated with more than one instance if you launch multiple instances using the same launch request. For example, if you launch one instance, you'll get one reservation ID. If you launch ten instances using the same launch request, you'll also get one reservation ID.

    • root-device-name - The name of the root device for the instance (for example, /dev/sda1 or /dev/xvda).

    • root-device-type - The type of root device that the instance uses (ebs | instance-store).

    • source-dest-check - Indicates whether the instance performs source/destination checking. A value of true means that checking is enabled, and false means checking is disabled. The value must be false for the instance to perform network address translation (NAT) in your VPC.

    • spot-instance-request-id - The ID of the Spot instance request.

    • state-reason-code - The reason code for the state change.

    • state-reason-message - A message that describes the state change.

    • subnet-id - The ID of the subnet for the instance.

    • tag:key=value - The key/value combination of a tag assigned to the resource. Specify the key of the tag in the filter name and the value of the tag in the filter value. For example, for the tag Purpose=X, specify tag:Purpose for the filter name and X for the filter value.

    • tag-key - The key of a tag assigned to the resource. This filter is independent of the tag-value filter. For example, if you use both the filter "tag-key=Purpose" and the filter "tag-value=X", you get any resources assigned both the tag key Purpose (regardless of what the tag's value is), and the tag value X (regardless of what the tag's key is). If you want to list only resources where Purpose is X, see the tag:key=value filter.

    • tag-value - The value of a tag assigned to the resource. This filter is independent of the tag-key filter.

    • tenancy - The tenancy of an instance (dedicated | default | host).

    • virtualization-type - The virtualization type of the instance (paravirtual | hvm).

    • vpc-id - The ID of the VPC that the instance is running in.

  • :instance_ids (Array<String>)

    One or more instance IDs.

    Default: Describes all your instances.

  • :dry_run (Boolean)

    Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.
