Updates the parameter values for stack instances for the specified accounts, within the specified Regions
Updates the parameter values for stack instances for the specified accounts, within the specified Regions. A stack instance refers to a stack in a specific account and Region.
You can only update stack instances in Regions and accounts where they
already exist; to create additional stack instances, use
create_stack_instances
.
During stack set updates, any parameters overridden for a stack instance are not updated, but retain their overridden value.
You can only update the parameter values that are specified in the
stack set; to add or delete a parameter itself, use
update_stack_set
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 update_stack_set
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
update_stack_instances
.
cloudformation_update_stack_instances(StackSetName, Accounts, DeploymentTargets, Regions, ParameterOverrides, OperationPreferences, OperationId)
StackSetName |
[required] The name or unique ID of the stack set associated with the stack instances. |
Accounts |
[ You can specify |
DeploymentTargets |
[ You can specify |
Regions |
[required] 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. |
ParameterOverrides |
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:
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
|
OperationPreferences |
Preferences for how AWS CloudFormation performs this stack set operation. |
OperationId |
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. |
A list with the following syntax:
list( OperationId = "string" )
svc$update_stack_instances( StackSetName = "string", Accounts = list( "string" ), DeploymentTargets = list( Accounts = list( "string" ), OrganizationalUnitIds = list( "string" ) ), Regions = list( "string" ), ParameterOverrides = list( list( ParameterKey = "string", ParameterValue = "string", UsePreviousValue = TRUE|FALSE, ResolvedValue = "string" ) ), OperationPreferences = list( RegionOrder = list( "string" ), FailureToleranceCount = 123, FailureTolerancePercentage = 123, MaxConcurrentCount = 123, MaxConcurrentPercentage = 123 ), OperationId = "string" )
