What are states of stack group and stack instance operations - Resource Orchestration Service

Resource Orchestration Service (ROS) assigns a state to each stack group operation and stack instance to indicate its progress.

Stack group operations

State	Description
RUNNING	The operation is in progress.
SUCCEEDED	The operation succeeded without exceeding the fault tolerance value.
FAILED	The operation failed because the number of stacks on which the operation failed exceeded the fault tolerance value.
STOPPING	The operation is being stopped.
STOPPED	The operation has been stopped.
QUEUED	The operation is queued. If ROS attempts to perform an automatic deployment operation on a service-managed stack group while another operation is running on that stack group, the automatic deployment operation is queued. For more information, see Enable automatic deployment for stacks.

State

Description

CURRENT

The stack instance is up to date with the stack group and has no ongoing or failed operations.

OUTDATED

The stack instance is not up to date with the stack group due to an ongoing or failed operation. Examples:

While ROS is updating a stack group or stack instance, the stack instance enters the OUTDATED state.
ROS fails to assume the required role when creating or updating a stack instance, so the associated stack operation is not executed.
ROS successfully assumes the required role but the operation to create or update the associated stack fails.
