list-stack-instances

Description

Returns summary information about stack instances that are associated with the specified stack set. You can filter for stack instances that are associated with a specific AWS account name or Region.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

list-stack-instances is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: Summaries

Synopsis

  list-stack-instances
--stack-set-name <value>
[--stack-instance-account <value>]
[--stack-instance-region <value>]
[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--stack-set-name (string)

The name or unique ID of the stack set that you want to list stack instances for.

--stack-instance-account (string)

The name of the AWS account that you want to list stack instances for.

--stack-instance-region (string)

The name of the Region where you want to list stack instances.

--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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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.

Examples

To list instances for a stack

The following list-stack-instances example lists the instances created from the specified stack set.

aws cloudformation list-stack-instances \
    --stack-set-name enable-config

The example output includes details about a stack that failed to update due to an error:

    "Summaries": [
        {
            "StackSetId": "enable-config:296a3360-xmpl-40af-be78-9341e95bf743",

Output

Summaries -> (list)

A list of StackInstanceSummary structures that contain information about the specified stack instances.

(structure)

The structure that contains summary information about a stack instance.

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)

[Self-managed permissions] The name of the AWS account that the stack instance is associated with.

StackId -> (string)

The ID of the stack instance.

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 assigned to this stack instance.

OrganizationalUnitId -> (string)

Reserved for internal use. No data returned.

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 : AWS CloudFormation has not 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 -> (timestamp)

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 has not yet been performed.

NextToken -> (string)

If the request doesn't return all of the remaining results, NextToken is set to a token. To retrieve the next set of results, call ListStackInstances again and assign that token to the request object's NextToken parameter. If the request returns all results, NextToken is set to null .
