During a terraform apply, a resource is successfully created but eventually fails during provisioning.
What happens to the resource?
A. The resource will be planned for destruction and recreation upon the next terraform apply
B. Terraform will retry to provision again.
C. The failure of provisioner will be ignored and it will not cause a failure to terraform apply
D. The resource will be automatically destroyed.
Correct Answer: A
Explanation/Reference:
Explanation:
If a creation-time provisioner fails, the resource is marked as tainted. A tainted resource will be planned for destruction and recreation upon the next terraform apply. Terraform does this because a failed provisioner can leave a resource in a semi-configured state. Because Terraform cannot reason about what the provisioner does, the only way to ensure proper creation of a resource is to recreate it. This is tainting.
You can change this behavior by setting the on_failure attribute, which is covered in detail below.
