Paws::OpsWorks::UpdateInstance - Arguments for method UpdateInstance on Paws::OpsWorks


This class represents the parameters used for calling the method UpdateInstance on the AWS OpsWorks service. Use the attributes of this class as arguments to method UpdateInstance.

You shouldn't make instances of this class. Each attribute should be used as a named argument in the call to UpdateInstance.


    my $opsworks = Paws->service('OpsWorks');

Values for attributes that are native types (Int, String, Float, etc) can passed as-is (scalar values). Values for complex Types (objects) can be passed as a HashRef. The keys and values of the hashref will be used to instance the underlying object. For the AWS API documentation, see


AgentVersion => Str

The default AWS OpsWorks Stacks agent version. You have the following options:

  • INHERIT - Use the stack's default agent version setting.

  • version_number - Use the specified agent version. This value overrides the stack's default setting. To update the agent version, you must edit the instance configuration and specify a new version. AWS OpsWorks Stacks then automatically installs that version on the instance.

The default setting is INHERIT. To specify an agent version, you must use the complete version number, not the abbreviated number shown on the console. For a list of available agent version numbers, call DescribeAgentVersions.

AgentVersion cannot be set to Chef 12.2.

AmiId => Str

The ID of the AMI that was used to create the instance. The value of this parameter must be the same AMI ID that the instance is already using. You cannot apply a new AMI to an instance by running UpdateInstance. UpdateInstance does not work on instances that are using custom AMIs.

Architecture => Str

The instance architecture. Instance types do not necessarily support both architectures. For a list of the architectures that are supported by the different instance types, see Instance Families and Types (

Valid values are: "x86_64", "i386"

AutoScalingType => Str

For load-based or time-based instances, the type. Windows stacks can use only time-based instances.

Valid values are: "load", "timer"

EbsOptimized => Bool

This property cannot be updated.

Hostname => Str

The instance host name.

InstallUpdatesOnBoot => Bool

Whether to install operating system and package updates when the instance boots. The default value is true. To control when updates are installed, set this value to false. You must then update your instances manually by using CreateDeployment to run the update_dependencies stack command or by manually running yum (Amazon Linux) or apt-get (Ubuntu) on the instances.

We strongly recommend using the default value of true, to ensure that your instances have the latest security updates.

REQUIRED InstanceId => Str

The instance ID.

InstanceType => Str

The instance type, such as t2.micro. For a list of supported instance types, open the stack in the console, choose Instances, and choose + Instance. The Size list contains the currently supported types. For more information, see Instance Families and Types ( The parameter values that you use to specify the various types are in the API Name column of the Available Instance Types table.

LayerIds => ArrayRef[Str|Undef]

The instance's layer IDs.

Os => Str

The instance's operating system, which must be set to one of the following. You cannot update an instance that is using a custom AMI.

  • A supported Linux operating system: An Amazon Linux version, such as Amazon Linux 2017.09, Amazon Linux 2017.03, Amazon Linux 2016.09, Amazon Linux 2016.03, Amazon Linux 2015.09, or Amazon Linux 2015.03.

  • A supported Ubuntu operating system, such as Ubuntu 16.04 LTS, Ubuntu 14.04 LTS, or Ubuntu 12.04 LTS.

  • CentOS Linux 7

  • Red Hat Enterprise Linux 7

  • A supported Windows operating system, such as Microsoft Windows Server 2012 R2 Base, Microsoft Windows Server 2012 R2 with SQL Server Express, Microsoft Windows Server 2012 R2 with SQL Server Standard, or Microsoft Windows Server 2012 R2 with SQL Server Web.

For more information about supported operating systems, see AWS OpsWorks Stacks Operating Systems (

The default option is the current Amazon Linux version. If you set this parameter to Custom, you must use the AmiId parameter to specify the custom AMI that you want to use. For more information about supported operating systems, see Operating Systems ( For more information about how to use custom AMIs with OpsWorks, see Using Custom AMIs (

You can specify a different Linux operating system for the updated stack, but you cannot change from Linux to Windows or Windows to Linux.

SshKeyName => Str

The instance's Amazon EC2 key name.
