CreateFleet - Amazon AppStream 2.0

CreateFleet

Creates a fleet. A fleet consists of streaming instances that your users access for their applications and desktops.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

ComputeCapacity

The desired capacity for the fleet. This is not allowed for Elastic fleets. For Elastic fleets, specify MaxConcurrentSessions instead.

Type: ComputeCapacity object

Required: No

Description

The description to display.

Type: String

Length Constraints: Maximum length of 256.

Required: No

DisconnectTimeoutInSeconds

The amount of time that a streaming session remains active after users disconnect. If users try to reconnect to the streaming session after a disconnection or network interruption within this time interval, they are connected to their previous session. Otherwise, they are connected to a new session with a new streaming instance.

Specify a value between 60 and 360000.

Type: Integer

Required: No

DisplayName

The fleet name to display.

Type: String

Length Constraints: Maximum length of 100.

Required: No

DomainJoinInfo

The name of the directory and organizational unit (OU) to use to join the fleet to a Microsoft Active Directory domain. This is not allowed for Elastic fleets.

Type: DomainJoinInfo object

Required: No

EnableDefaultInternetAccess

Enables or disables default internet access for the fleet.

Type: Boolean

Required: No

FleetType

The fleet type.

ALWAYS_ON

Provides users with instant-on access to their apps. You are charged for all running instances in your fleet, even if no users are streaming apps.

ON_DEMAND

Provide users with access to applications after they connect, which takes one to two minutes. You are charged for instance streaming when users are connected and a small hourly fee for instances that are not streaming apps.

Type: String

Valid Values: ALWAYS_ON | ON_DEMAND | ELASTIC

Required: No

IamRoleArn

The Amazon Resource Name (ARN) of the IAM role to apply to the fleet. To assume a role, a fleet instance calls the AWS Security Token Service (STS) AssumeRole API operation and passes the ARN of the role to use. The operation creates a new session with temporary credentials. AppStream 2.0 retrieves the temporary credentials and creates the appstream_machine_role credential profile on the instance.

For more information, see Using an IAM Role to Grant Permissions to Applications and Scripts Running on AppStream 2.0 Streaming Instances in the Amazon AppStream 2.0 Administration Guide.

Type: String

Pattern: ^arn:aws(?:\-cn|\-iso\-b|\-iso|\-us\-gov)?:[A-Za-z0-9][A-Za-z0-9_/.-]{0,62}:[A-Za-z0-9_/.-]{0,63}:[A-Za-z0-9_/.-]{0,63}:[A-Za-z0-9][A-Za-z0-9:_/+=,@.\\-]{0,1023}$

Required: No

IdleDisconnectTimeoutInSeconds

The amount of time that users can be idle (inactive) before they are disconnected from their streaming session and the DisconnectTimeoutInSeconds time interval begins. Users are notified before they are disconnected due to inactivity. If they try to reconnect to the streaming session before the time interval specified in DisconnectTimeoutInSeconds elapses, they are connected to their previous session. Users are considered idle when they stop providing keyboard or mouse input during their streaming session. File uploads and downloads, audio in, audio out, and pixels changing do not qualify as user activity. If users continue to be idle after the time interval in IdleDisconnectTimeoutInSeconds elapses, they are disconnected.

To prevent users from being disconnected due to inactivity, specify a value of 0. Otherwise, specify a value between 60 and 3600. The default value is 0.

Note

If you enable this feature, we recommend that you specify a value that corresponds exactly to a whole number of minutes (for example, 60, 120, and 180). If you don't do this, the value is rounded to the nearest minute. For example, if you specify a value of 70, users are disconnected after 1 minute of inactivity. If you specify a value that is at the midpoint between two different minutes, the value is rounded up. For example, if you specify a value of 90, users are disconnected after 2 minutes of inactivity.

Type: Integer

Required: No

ImageArn

The ARN of the public, private, or shared image to use.

Type: String

Pattern: ^arn:aws(?:\-cn|\-iso\-b|\-iso|\-us\-gov)?:[A-Za-z0-9][A-Za-z0-9_/.-]{0,62}:[A-Za-z0-9_/.-]{0,63}:[A-Za-z0-9_/.-]{0,63}:[A-Za-z0-9][A-Za-z0-9:_/+=,@.\\-]{0,1023}$
