This page describes how to use Infrastructure Manager to preview the deletion of an
existing deployment.
A preview describes the actions to actuate a specific Terraform configuration.
Before you delete a deployment, you can use a preview to verify the resources
that are planned to be deleted.
A preview does not delete any provisioned resources. To delete a deployment,
including deleting provisioned resources, seeDelete deployments.
A preview executes theTerraform plancommand. This page assumes you are
familiar with Terraform. For details, seeTerraform and Infrastructure Manager.
Identify the Terraform configuration to preview. Ensure this Terraform
configuration complies with theconstraints,
including that the configuration does not contain sensitive data.
If you want to store the Terraform configuration in a storage bucket, ensure
the Terraform configuration is uploaded to a Cloud Storage bucket. SeeUpload a configuration to a storage bucketfor more details.
A storage bucket lets you control access to the configuration. You
can also deploy a Terraform configuration that is stored in a
public Git repository, or stored on your
local machine.
Preview the deletion of a deployment
Before you delete a deployment, you can preview and review the deletion.
