.. py:method:: AppStream.Client.update_fleet(**kwargs)

  

  Updates the specified fleet.

   

  If the fleet is in the ``STOPPED`` state, you can update any attribute except the fleet name.

   

  If the fleet is in the ``RUNNING`` state, you can update the following based on the fleet type:

   

  
  * Always-On and On-Demand fleet types You can update the ``DisplayName``, ``ComputeCapacity``, ``ImageARN``, ``ImageName``, ``IdleDisconnectTimeoutInSeconds``, and ``DisconnectTimeoutInSeconds`` attributes.
   
  * Elastic fleet type You can update the ``DisplayName``, ``IdleDisconnectTimeoutInSeconds``, ``DisconnectTimeoutInSeconds``, ``MaxConcurrentSessions``, ``SessionScriptS3Location`` and ``UsbDeviceFilterStrings`` attributes.
  

   

  If the fleet is in the ``STARTING`` or ``STOPPED`` state, you can't update it.

      The desired number of streaming instances.

      

    
    - **DesiredSessions** *(integer) --* 

      The desired number of user sessions for a multi-session fleet. This is not allowed for single-session fleets.

       

      When you create a fleet, you must set either the DesiredSessions or DesiredInstances attribute, based on the type of fleet you create. You can’t define both attributes or leave both attributes blank.

      

    
  
  :type VpcConfig: dict
  :param VpcConfig: 

    The VPC configuration for the fleet. This is required for Elastic fleets, but not required for other fleet types. Elastic fleets require that you specify at least two subnets in different availability zones.

    

  
    - **SubnetIds** *(list) --* 

      The identifiers of the subnets to which a network interface is attached from the fleet instance or image builder instance. Fleet instances use one or more subnets. Image builder instances use one subnet.

      

    
      - *(string) --* 

      
  
    - **SecurityGroupIds** *(list) --* 

      The identifiers of the security groups for the fleet or image builder.

      

    
      - *(string) --* 

      
  
  
  :type MaxUserDurationInSeconds: integer
  :param MaxUserDurationInSeconds: 

    The maximum amount of time that a streaming session can remain active, in seconds. If users are still connected to a streaming instance five minutes before this limit is reached, they are prompted to save any open documents before being disconnected. After this time elapses, the instance is terminated and replaced by a new instance.

     

    Specify a value between 600 and 432000.

    

  
  :type DisconnectTimeoutInSeconds: integer
  :param 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 36000.

    

  
  :type DeleteVpcConfig: boolean
  :param DeleteVpcConfig: 

    Deletes the VPC association for the specified fleet.

    

  
  :type Description: string
  :param Description: 

    The description to display.

    

  
  :type DisplayName: string
  :param DisplayName: 

    The fleet name to display.

    

  
  :type EnableDefaultInternetAccess: boolean
  :param EnableDefaultInternetAccess: 

    Enables or disables default internet access for the fleet.

    

  
  :type DomainJoinInfo: dict
  :param DomainJoinInfo: 

    The name of the directory and organizational unit (OU) to use to join the fleet to a Microsoft Active Directory domain.

    

  
    - **DirectoryName** *(string) --* 

      The fully qualified name of the directory (for example, corp.example.com).

      

    
    - **OrganizationalUnitDistinguishedName** *(string) --* 

      The distinguished name of the organizational unit for computer accounts.

      

    
  
  :type IdleDisconnectTimeoutInSeconds: integer
  :param 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 users 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 36000. 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 AttributesToDelete: list
  :param AttributesToDelete: 

    The fleet attributes to delete.

    

  
    - *(string) --* 

      The fleet attribute.

      

    

  :type IamRoleArn: string
  :param 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. WorkSpaces Applications 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 WorkSpaces Applications Streaming Instances <https://docs.aws.amazon.com/appstream2/latest/developerguide/using-iam-roles-to-grant-permissions-to-applications-scripts-streaming-instances.html>`__ in the *Amazon WorkSpaces Applications Administration Guide*.

    

  
  :type StreamView: string
  :param StreamView: 

    The WorkSpaces Applications view that is displayed to your users when they stream from the fleet. When ``APP`` is specified, only the windows of applications opened by users display. When ``DESKTOP`` is specified, the standard desktop that is provided by the operating system displays.

     

    The default value is ``APP``.

    

  
  :type Platform: string
  :param Platform: 

    The platform of the fleet. WINDOWS_SERVER_2019, AMAZON_LINUX2 and UBUNTU_PRO_2404 are supported for Elastic fleets.

    

  
  :type MaxConcurrentSessions: integer
  :param MaxConcurrentSessions: 

    The maximum number of concurrent sessions for a fleet.

    

  
  :type UsbDeviceFilterStrings: list
  :param UsbDeviceFilterStrings: 

    The USB device filter strings that specify which USB devices a user can redirect to the fleet streaming session, when using the Windows native client. This is allowed but not required for Elastic fleets.

    

  
    - *(string) --* 

    

  :type SessionScriptS3Location: dict
  :param SessionScriptS3Location: 

    The S3 location of the session scripts configuration zip file. This only applies to Elastic fleets.

    

  
    - **S3Bucket** *(string) --* **[REQUIRED]** 

      The S3 bucket of the S3 object.

      

    
    - **S3Key** *(string) --* 

      The S3 key of the S3 object.

       

      This is required when used for the following:

       

      
      * IconS3Location (Actions: CreateApplication and UpdateApplication)
       
      * SessionScriptS3Location (Actions: CreateFleet and UpdateFleet)
       
      * ScriptDetails (Actions: CreateAppBlock)
       
      * SourceS3Location when creating an app block with ``CUSTOM`` PackagingType (Actions: CreateAppBlock)
       
      * SourceS3Location when creating an app block with ``APPSTREAM2`` PackagingType, and using an existing application package (VHD file). In this case, ``S3Key`` refers to the VHD file. If a new application package is required, then ``S3Key`` is not required. (Actions: CreateAppBlock)
      

      

    
  
  :type MaxSessionsPerInstance: integer
  :param MaxSessionsPerInstance: 

    The maximum number of user sessions on an instance. This only applies to multi-session fleets.

    

  
  :type RootVolumeConfig: dict
  :param RootVolumeConfig: 

    The updated configuration for the root volume of fleet instances. Note that volume size cannot be decreased below the image volume size.

    

  
    - **VolumeSizeInGb** *(integer) --* 

      The size of the root volume in GB. Valid range is 200-500 GB. The default is 200 GB, which is included in the hourly instance rate. Additional storage beyond 200 GB incurs extra charges and applies to instances regardless of their running state.

        - **IdleDisconnectTimeoutInSeconds** *(integer) --* 

          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 users 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 36000. 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.

            

          
        

        - **IamRoleArn** *(string) --* 

          The ARN of the IAM role that is applied to the fleet. To assume a role, the 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. WorkSpaces Applications 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 WorkSpaces Applications Streaming Instances <https://docs.aws.amazon.com/appstream2/latest/developerguide/using-iam-roles-to-grant-permissions-to-applications-scripts-streaming-instances.html>`__ in the *Amazon WorkSpaces Applications Administration Guide*.

          
        

        - **StreamView** *(string) --* 

          The WorkSpaces Applications view that is displayed to your users when they stream from the fleet. When ``APP`` is specified, only the windows of applications opened by users display. When ``DESKTOP`` is specified, the standard desktop that is provided by the operating system displays.
