Destroy Infrastructure
We've now seen how to build and change infrastructure. Before we move on to creating multiple resources and showing resource dependencies, we're going to go over how to completely destroy the Terraform-managed infrastructure.
Destroying your infrastructure is a rare event in production environments. But if you're using Terraform to spin up multiple environments such as development, test, QA environments, then destroying is a useful action.
Plan
Before destroying our infrastructure, we can use the plan command to see what resources Terraform will destroy.
$ terraform plan -destroy
...
- aws_instance.example
With the -destroy flag, we're asking Terraform to plan a destroy,
where all resources under Terraform management are destroyed. You can
use this output to verify exactly what resources Terraform is managing
and will destroy.
Destroy
Let's destroy the infrastructure now:
$ terraform destroy
aws_instance.example: Destroying...
Apply complete! Resources: 0 added, 0 changed, 1 destroyed.
...
The terraform destroy command should ask you to verify that you
really want to destroy the infrastructure. Terraform only accepts the
literal "yes" as an answer as a safety mechanism. Once entered, Terraform
will go through and destroy the infrastructure.
Just like with apply, Terraform is smart enough to determine what order
things should be destroyed. In our case, we only had one resource, so there
wasn't any ordering necessary. But in more complicated cases with multiple
resources, Terraform will destroy in the proper order.
Next
You now know how to create, modify, and destroy infrastructure. With these building blocks, you can effectively experiment with any part of Terraform.
Next, we move on to features that make Terraform configurations slightly more useful: variables, resource dependencies, provisioning, and more.
