Only attributes defined by the resource type can be ignored.

`ignore_changes` cannot be applied to itself or to any other meta-arguments.

* `replace_triggered_by` (list of resource references) - A list of expressions
|
||||
referencing managed resources, instances, or instance attributes can be
|
||||
supplied to `replace_triggered_by` to force replacement of the parent
|
||||
resource when there is a change in the referenced value. When the containing
|

resource is using `count` or `for_each`, `count.index` or `each.key` may be
|

used in the expression to index specific instances.
|

* `replace_triggered_by` (list of resource references) - Forces Terraform to replace the parent resource when there is a change to a referenced resource or resource attribute. Supply a list of expressions referencing managed resources, instances, or instance attributes. When the containing resource uses `count` or `for_each`, you can use `count.index` or `each.key` in the expression to index specific instances.

`replace_triggered_by` is used to couple the lifecycles of otherwise
|
||||
independent resources, allowing the configurable replacement of a resource
|
||||
based on conditions in a dependency. Given the three classes of references
|
||||
allowed in `replace_triggered_by`, the following conditions can apply:
|
||||
References trigger replacement in the following conditions:
|
||||
- If the reference is to a resource with multiple instances, a plan to
|
||||
update or replace any instance will trigger replacement.
|
||||
- If the reference is to a single resource instance, a plan to update or
|
||||
replace that instance will trigger replacement.
|
||||
- If the reference is to a single attribute of a resource instance, any
|
||||
difference in the before and after value will trigger replacement.
|
||||
change to the attribute value will trigger replacement.
|
||||
|
||||
Only managed resources are allowed in the `replace_triggered_by` arguments.

Because the `replace_triggered_by` expressions are used to lookup changes in
