[ aws . cloudformation ]



Returns the stack instance that's associated with the specified stack set, AWS account, and region.

For a list of stack instances that are associated with a specific stack set, use ListStackInstances .

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.


--stack-set-name <value>
--stack-instance-account <value>
--stack-instance-region <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--stack-set-name (string)

The name or the unique stack ID of the stack set that you want to get stack instance information for.

--stack-instance-account (string)

The ID of an AWS account that's associated with this stack instance.

--stack-instance-region (string)

The name of a region that's associated with this stack instance.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.


StackInstance -> (structure)

The stack instance that matches the specified request parameters.

StackSetId -> (string)

The name or unique ID of the stack set that the stack instance is associated with.

Region -> (string)

The name of the AWS region that the stack instance is associated with.

Account -> (string)

The name of the AWS account that the stack instance is associated with.

StackId -> (string)

The ID of the stack instance.

ParameterOverrides -> (list)

A list of parameters from the stack set template whose values have been overridden in this stack instance.


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, AWS CloudFormation uses the default value that is 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 Systems Manager parameter key. This field is returned only for ` SSM parameter types <>`__ in the template.

Status -> (string)

The status of the stack instance, in terms of its synchronization with its associated stack set.

  • INOPERABLE : A DeleteStackInstances operation has failed and left the stack in an unstable state. Stacks in this state are excluded from further UpdateStackSet operations. You might need to perform a DeleteStackInstances operation, with RetainStacks set to true , to delete the stack instance, and then delete the stack manually.
  • OUTDATED : The stack isn't currently up to date with the stack set because:
    • The associated stack failed during a CreateStackSet or UpdateStackSet operation.
    • The stack was part of a CreateStackSet or UpdateStackSet operation that failed or was stopped before the stack was created or updated.
  • CURRENT : The stack is currently up to date with the stack set.

StatusReason -> (string)

The explanation for the specific status code that is assigned to this stack instance.
