The following Terraform commands are used to create, manage, and delete resources:
terraform init - Initializes Terraform. terraform plan - Shows the list of actions. terraform plan -out=plan_store - Stores and directly applies the plan. terraform apply plan_store - Stores a plan in the plan_store. terraform apply - Shows the list of actions and asks for permission to apply the plan's actions. terraform destroy - Destroys all the resources created with Terraform.
- By storing a plan in the
plan_store, the permission query is bypassed when applying the plan.
- When a folder contains all types of
.tffiles, only a particular type of
.tffile should be executed.
To execute a single type file, use the following commands:
terraform init terraform plan -out=plan_store -target="resource_name.logical_name"
For example, to create only instances, use the following commands:
terraform plan -out=plan_store -target="google_compute_instance.instanceTest" terraform apply plan_store
