create_stack_instances#

CloudFormation.Client.create_stack_instances(**kwargs)#

Parameters:

StackSetName (string) –
[REQUIRED]

The name or unique ID of the stack set that you want to create stack instances from.
Accounts (list) –
[Self-managed permissions] The names of one or more Amazon Web Services accounts that you want to create stack instances in the specified Region(s) for.

You can specify Accounts or DeploymentTargets, but not both.
- (string) –
DeploymentTargets (dict) –
[Service-managed permissions] The Organizations accounts for which to create stack instances in the specified Amazon Web Services Regions.

You can specify Accounts or DeploymentTargets, but not both.
- Accounts (list) –
  
  The names of one or more Amazon Web Services accounts for which you want to deploy stack set updates.
  - (string) –
- AccountsUrl (string) –
  
  Returns the value of the AccountsUrl property.
- OrganizationalUnitIds (list) –
  
  The organization root ID or organizational unit (OU) IDs to which StackSets deploys.
  - (string) –
- AccountFilterType (string) –
  
  Limit deployment targets to individual accounts or include additional accounts with provided OUs.
  
  The following is a list of possible values for the AccountFilterType operation.
  - INTERSECTION: StackSets deploys to the accounts specified in Accounts parameter.
  - DIFFERENCE: StackSets excludes the accounts specified in Accounts parameter. This enables user to avoid certain accounts within an OU such as suspended accounts.
  - UNION: StackSets includes additional accounts deployment targets. This is the default value if AccountFilterType is not provided. This enables user to update an entire OU and individual accounts from a different OU in one request, which used to be two separate requests.
  - NONE: Deploys to all the accounts in specified organizational units (OU).
Regions (list) –
[REQUIRED]

The names of one or more Amazon Web Services Regions where you want to create stack instances using the specified Amazon Web Services accounts.
- (string) –
ParameterOverrides (list) –
A list of stack set parameters whose values you want to override in the selected stack instances.

Any overridden parameter values will be applied to all stack instances in the specified accounts and Amazon Web Services Regions. When specifying parameters and their values, be aware of how CloudFormation sets parameter values during stack instance operations:
- To override the current value for a parameter, include the parameter and specify its value.
- To leave an overridden parameter set to its present value, include the parameter and specify UsePreviousValue as true. (You can’t specify both a value and set UsePreviousValue to true.)
- To set an overridden parameter back to the value specified in the stack set, specify a parameter list but don’t include the parameter in the list.
- To leave all parameters set to their present values, don’t specify this property at all.
During stack set updates, any parameter values overridden for a stack instance aren’t 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.
- (dict) –
  
  The Parameter data type.
  - ParameterKey (string) –
    
    The key associated with the parameter. If you don’t specify a key and value for a particular parameter, CloudFormation uses the default value that’s specified in your template.
  - ParameterValue (string) –
    
    The input value associated with the parameter.
  - UsePreviousValue (boolean) –
    
    During a stack update, use the existing parameter value that the stack is using for a given parameter key. If you specify true, do not specify a parameter value.
  - ResolvedValue (string) –
    
    Read-only. The value that corresponds to a SSM parameter key. This field is returned only for `SSM <https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html#aws-ssm-parameter-types>`__parameter types in the template.
OperationPreferences (dict) –
Preferences for how CloudFormation performs this stack set operation.
- RegionConcurrencyType (string) –
  
  The concurrency type of deploying StackSets operations in Regions, could be in parallel or one Region at a time.
- RegionOrder (list) –
  
  The order of the Regions in where you want to perform the stack operation.
  - (string) –
- FailureToleranceCount (integer) –
  
  The number of accounts, per Region, for which this operation can fail before CloudFormation stops the operation in that Region. If the operation is stopped in a Region, CloudFormation doesn’t attempt the operation in any subsequent Regions.
  
  Conditional: You must specify either FailureToleranceCount or FailureTolerancePercentage (but not both).
  
  By default, 0 is specified.
- FailureTolerancePercentage (integer) –
  
  The percentage of accounts, per Region, for which this stack operation can fail before CloudFormation stops the operation in that Region. If the operation is stopped in a Region, CloudFormation doesn’t attempt the operation in any subsequent Regions.
  
  When calculating the number of accounts based on the specified percentage, CloudFormation rounds down to the next whole number.
  
  Conditional: You must specify either FailureToleranceCount or FailureTolerancePercentage, but not both.
  
  By default, 0 is specified.
- MaxConcurrentCount (integer) –
  
  The maximum number of accounts in which to perform this operation at one time. This is dependent on the value of FailureToleranceCount. MaxConcurrentCount is at most one more than the FailureToleranceCount.
  
  Note that this setting lets you specify the maximum for operations. For large deployments, under certain circumstances the actual number of accounts acted upon concurrently may be lower due to service throttling.
  
  Conditional: You must specify either MaxConcurrentCount or MaxConcurrentPercentage, but not both.
  
  By default, 1 is specified.
- MaxConcurrentPercentage (integer) –
  
  The maximum percentage of accounts in which to perform this operation at one time.
  
  When calculating the number of accounts based on the specified percentage, CloudFormation rounds down to the next whole number. This is true except in cases where rounding down would result is zero. In this case, CloudFormation sets the number as one instead.
  
  Note that this setting lets you specify the maximum for operations. For large deployments, under certain circumstances the actual number of accounts acted upon concurrently may be lower due to service throttling.
  
  Conditional: You must specify either MaxConcurrentCount or MaxConcurrentPercentage, but not both.
  
  By default, 1 is specified.
OperationId (string) –
The unique identifier for this stack set operation.

The operation ID also functions as an idempotency token, to ensure that 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 CloudFormation successfully received them.

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

Repeating this stack set operation with a new operation ID retries all stack instances whose status is OUTDATED.

This field is autopopulated if not provided.
CallAs (string) –
[Service-managed permissions] Specifies whether you are acting as an account administrator in the organization’s management account or as a delegated administrator in a member account.

By default, SELF is specified. Use SELF for stack sets with self-managed permissions.
- If you are signed in to the management account, specify SELF.
- If you are signed in to a delegated administrator account, specify DELEGATED_ADMIN. Your Amazon Web Services account must be registered as a delegated administrator in the management account. For more information, see Register a delegated administrator in the CloudFormation User Guide.
