StackInstanceSummary

The structure that contains summary information about a stack instance.

Account

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

Type: String

Pattern: ^[0-9]{12}$

Required: No

DriftStatus

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.

Type: String

Valid Values: DRIFTED | IN_SYNC | UNKNOWN | NOT_CHECKED

Required: No

LastDriftCheckTimestamp

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.

Type: Timestamp

Required: No

LastOperationId

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

Type: String

Length Constraints: Minimum length of 1. Maximum length of 128.

Pattern: [a-zA-Z0-9][-a-zA-Z0-9]*

Required: No

OrganizationalUnitId

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

Type: String

Pattern: ^(ou-[a-z0-9]{4,32}-[a-z0-9]{8,32}|r-[a-z0-9]{4,32})$

Required: No

Region

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

Type: String

Pattern: ^[a-zA-Z0-9-]{1,128}$

Required: No

StackId

The ID of the stack instance.

Type: String

Required: No

StackInstanceStatus

The detailed status of the stack instance.

Type: StackInstanceComprehensiveStatus object

Required: No

StackSetId

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

Type: String

Required: No

Status

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. INOPERABLE can be returned here when the cause is a failed import. If it's due to a failed import, the operation can be retried once the failures are fixed. To see if this is due to a failed import, call the DescribeStackInstance API operation, look at the DetailedStatus member returned in the StackInstanceSummary member.
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.

Type: String

Valid Values: CURRENT | OUTDATED | INOPERABLE

Required: No

StatusReason

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

Type: String

Required: No
