describe_stack_instance(**kwargs)

Returns the stack instance that's associated with the specified stack set, Amazon Web Services account, and Region.

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

Request Syntax

response = client.describe_stack_instance(
    StackSetName='string',
    StackInstanceAccount='string',
    StackInstanceRegion='string',
    CallAs='SELF'|'DELEGATED_ADMIN'
)

Parameters

• StackSetName (string) --

  [REQUIRED]

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

• StackInstanceAccount (string) --

  [REQUIRED]

  The ID of an Amazon Web Services account that's associated with this stack instance.

• StackInstanceRegion (string) --

  [REQUIRED]

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

• 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 .

Response Structure

• (dict) --

  • StackInstance (dict) --

    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 Amazon Web Services Region that the stack instance is associated with.

    • Account (string) --

      [Self-managed permissions] The name of the Amazon Web Services 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.

      • (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 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.

    • StackInstanceStatus (dict) --

      The detailed status of the stack instance.

      • DetailedStatus (string) --
        • CANCELLED : The operation in the specified account and Region has been canceled. This is either because a user has stopped the stack set operation, or because the failure tolerance of the stack set operation has been exceeded.
        • FAILED : The operation in the specified account and Region failed. If the stack set operation fails in enough accounts within a Region, the failure tolerance for the stack set operation as a whole might be exceeded.
        • 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.
        • PENDING : The operation in the specified account and Region has yet to start.
        • RUNNING : The operation in the specified account and Region is currently in progress.
        • SUCCEEDED : The operation in the specified account and Region completed successfully.

    • StatusReason (string) --

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

    • OrganizationalUnitId (string) --

      [Service-managed permissions] The organization root ID or organizational unit (OU) IDs that you specified for DeploymentTargets.

    • DriftStatus (string) --

      Status of the stack instance's actual configuration compared to the expected template and parameter configuration of the stack set to which it belongs.

      • DRIFTED : The stack differs from the expected template and parameter configuration of the stack set to which it belongs. A stack instance is considered to have drifted if one or more of the resources in the associated stack have drifted.
      • NOT_CHECKED : CloudFormation hasn't checked if the stack instance differs from its expected stack set configuration.
      • IN_SYNC : The stack instance's actual configuration matches its expected stack set configuration.
      • UNKNOWN : This value is reserved for future use.

    • LastDriftCheckTimestamp (datetime) --

      Most recent time when CloudFormation performed a drift detection operation on the stack instance. This value will be NULL for any stack instance on which drift detection hasn't yet been performed.

    • LastOperationId (string) --

      The last unique ID of a StackSet operation performed on a stack instance.
