A stack is a collection of ROS resources that you can manage as a single unit. You can create, update, or delete a stack to create, update, or delete a collection of resources.
All resources included in each stack are defined by the template of the stack. If a resource cannot be created, ROS rolls back the stack and deletes all associated resources that were created. If a resource cannot be deleted, all remaining resources are retained until the stack can be deleted.
|Create a stack||When you create a stack, you must select a template and configure template parameters, stack policies, and deletion protection.|
|View information about a stack||You can view basic information about a stack on the stack management page.|
|Update a stack||To modify only the current template and configurations of a specified stack while leaving the region unchanged, you must update the stack.|
|Recreate a stack||To modify the current template and configurations of a specified stack and the region where the stack resides, you must recreate the stack.|
|Delete a stack||When you no longer need a stack and its resources, you can delete the stack and all of its associated resources from the specified target accounts within the specified regions.|
|Enable deletion protection||To prevent a stack from being deleted in an unexpected manner, you can enable deletion protection. Stacks with deletion protection enabled cannot be deleted.|
|Use nested stacks||Nested stacks can themselves contain other nested stacks, resulting in a hierarchy of stacks. A root stack is the parent stack to which all of the nested stacks belong. You can view the parent stack of a nested stack in the ROS console.|
|Stack policies||When you create a stack, all update operations are allowed on all resources. By default, anyone with stack update permissions can update all resources in the stack. During an update, some resources may be interrupted. You can use a stack policy to prevent stack resources from being updated or deleted in an unexpected manner during a stack update.|
