Question

A platform engineer wants to guarantee that an AWS S3 bucket created by Terraform always has versioning explicitly enabled before the apply is considered valid. They want the apply to fail with a clear error if the resulting resource does not meet this requirement, evaluated against the resource's own attributes after planning. Which Terraform feature should they use?

Accepted Answer

A `lifecycle` block with a `precondition` referencing the resource's versioning attribute

Answer

A `validation` block inside the `variable` definition for the bucket name

Answer

A `lifecycle` block with `ignore_changes` set to the versioning attribute

Answer

A `depends_on` argument pointing to the versioning configuration resource
