describe-stack-instance

Description

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.

Synopsis

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

Options

--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 | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. 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 describe a stack instance

The following command describes an instance of the specified stack set in the specified account and Region. The stack set is in the current region and account, and the instance is in the us-west-2 region in account 123456789012.:

aws cloudformation describe-stack-instance \
    --stack-set-name my-stack-set \
    --stack-instance-account 123456789012 \
    --stack-instance-region us-west-2

Output:

{
    "StackInstance": {
        "StackSetId": "enable-config:296a3360-xmpl-40af-be78-9341e95bf743",
        "Region": "us-west-2",
        "Account": "123456789012",
        "StackId": "arn:aws:cloudformation:us-west-2:123456789012:stack/StackSet-enable-config-e6cac20f-xmpl-46e9-8314-53e0d4591532/4287f9a0-e615-xmpl-894a-12b31d3117be",
        "ParameterOverrides": [],
        "Status": "OUTDATED",
        "StatusReason": "ResourceLogicalId:ConfigBucket, ResourceType:AWS::S3::Bucket, ResourceStatusReason:You have attempted to create more buckets than allowed (Service: Amazon S3; Status Code: 400; Error Code: TooManyBuckets; Request ID: F7F21CXMPL580224; S3 Extended Request ID: egd/Fdt89BXMPLyiqbMNljVk55Yqqvi3NYW2nKLUVWhUGEhNfCmZdyj967lhriaG/dWMobSO40o=)."

Output

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)

[Self-managed permissions] 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.

(structure)

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 <https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html#aws-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 -> (structure)

The detailed status of the stack instance.

DetailedStatus -> (string)

• CANCELLED : The operation in the specified account and Region has been cancelled. 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 is 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 : 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.
