NAME

Paws::CloudFormation::UpdateStackInstances - Arguments for method UpdateStackInstances on Paws::CloudFormation

DESCRIPTION

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

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

SYNOPSIS

    my $cloudformation = Paws->service('CloudFormation');
    my $UpdateStackInstancesOutput = $cloudformation->UpdateStackInstances(
      Accounts     => [ 'MyAccount', ... ],
      Regions      => [ 'MyRegion',  ... ],
      StackSetName => 'MyStackSetNameOrId',
      OperationId          => 'MyClientRequestToken',    # OPTIONAL
      OperationPreferences => {
        FailureToleranceCount      => 1,    # OPTIONAL
        FailureTolerancePercentage => 1,    # max: 100; OPTIONAL
        MaxConcurrentCount         => 1,    # min: 1; OPTIONAL
        MaxConcurrentPercentage    => 1,    # min: 1, max: 100; OPTIONAL
        RegionOrder => [ 'MyRegion', ... ],
      },    # OPTIONAL
      ParameterOverrides => [
        {
          ParameterKey     => 'MyParameterKey',      # OPTIONAL
          ParameterValue   => 'MyParameterValue',    # OPTIONAL
          ResolvedValue    => 'MyParameterValue',    # OPTIONAL
          UsePreviousValue => 1,                     # OPTIONAL
        },
        ...
      ],                                             # OPTIONAL
    );

    # Results:
    my $OperationId = $UpdateStackInstancesOutput->OperationId;

    # Returns a L<Paws::CloudFormation::UpdateStackInstancesOutput> object.

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 https://docs.aws.amazon.com/goto/WebAPI/cloudformation/UpdateStackInstances

ATTRIBUTES

REQUIRED Accounts => ArrayRef[Str|Undef]

The names of one or more AWS accounts for which you want to update parameter values for stack instances. The overridden parameter values will be applied to all stack instances in the specified accounts and regions.

OperationId => Str

The unique identifier for this stack set operation.

The operation ID also functions as an idempotency token, to ensure that AWS CloudFormation performs the stack set operation only once, even if you retry the request multiple times. You might retry stack set operation requests to ensure that AWS CloudFormation successfully received them.

If you don't specify an operation ID, the SDK generates one automatically.

OperationPreferences => Paws::CloudFormation::StackSetOperationPreferences

Preferences for how AWS CloudFormation performs this stack set operation.

ParameterOverrides => ArrayRef[Paws::CloudFormation::Parameter]

A list of input parameters whose values you want to update for the specified stack instances.

Any overridden parameter values will be applied to all stack instances in the specified accounts and regions. When specifying parameters and their values, be aware of how AWS CloudFormation sets parameter values during stack instance update operations:

• To override the current value for a parameter, include the parameter and specify its value.

• To leave a parameter set to its present value, you can do one of the following:

  • Do not include the parameter in the list.

  • Include the parameter and specify UsePreviousValue as true. (You cannot specify both a value and set UsePreviousValue to true.)

• To set all overridden parameter back to the values specified in the stack set, specify a parameter list but do not include any parameters.

• To leave all parameters set to their present values, do not specify this property at all.

During stack set updates, any parameter values overridden for a stack instance are not updated, but retain their overridden value.

You can only override the parameter values that are specified in the stack set; to add or delete a parameter itself, use UpdateStackSet to update the stack set template. If you add a parameter to a template, before you can override the parameter value specified in the stack set you must first use UpdateStackSet (http://docs.aws.amazon.com/AWSCloudFormation/latest/APIReference/API_UpdateStackSet.html) to update all stack instances with the updated template and parameter value specified in the stack set. Once a stack instance has been updated with the new parameter, you can then override the parameter value using UpdateStackInstances.

REQUIRED Regions => ArrayRef[Str|Undef]

The names of one or more regions in which you want to update parameter values for stack instances. The overridden parameter values will be applied to all stack instances in the specified accounts and regions.

REQUIRED StackSetName => Str

The name or unique ID of the stack set associated with the stack instances.
