StackInstance

Structure Class

StackInstance dataclass

Bases: _SerdeShape

A CloudFormation stack, in a specific account and Region, that's part of a StackSet operation. A stack instance is a reference to an attempted or actual stack in a given account within a given Region. A stack instance can exist without a stack---for example, if the stack couldn't be created for some reason. A stack instance is associated with only one StackSet. Each stack instance contains the ID of its associated StackSet, in addition to the ID of the actual stack and the stack status.

Attributes

account class-attribute instance-attribute 
account: str | None = ...

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

drift_status class-attribute instance-attribute 
drift_status: str | None = ...

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

  • DRIFTED: The stack differs from the expected template and parameter configuration of the StackSet it belongs to. 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 StackSet configuration.

  • IN_SYNC: The stack instance's actual configuration matches its expected StackSset configuration.

  • UNKNOWN: This value is reserved for future use.

last_drift_check_timestamp class-attribute instance-attribute 
last_drift_check_timestamp: datetime | None = ...

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

last_operation_id class-attribute instance-attribute 
last_operation_id: str | None = ...

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

organizational_unit_id class-attribute instance-attribute 
organizational_unit_id: str | None = ...

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

parameter_overrides class-attribute instance-attribute 
parameter_overrides: list[Parameter] | None = ...

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

region class-attribute instance-attribute 
region: str | None = ...

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

stack_id class-attribute instance-attribute 
stack_id: str | None = ...

The ID of the stack instance.

stack_instance_status class-attribute instance-attribute 
stack_instance_status: StackInstanceComprehensiveStatus | None = ...

The detailed status of the stack instance.

stack_set_id class-attribute instance-attribute 
stack_set_id: str | None = ...

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

status class-attribute instance-attribute 
status: str | None = ...

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, look at the DetailedStatus member in the StackInstanceSummary member that is a peer to this Status member.

  • OUTDATED: The stack isn't currently up to date with the StackSet 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 StackSet.

status_reason class-attribute instance-attribute 
status_reason: str | None = ...

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