The terraform init command is used to initialize a working directory containing Terraform configuration files. This is the first command that should be run after writing a new Terraform configuration or cloning an existing one from version control. It is safe to run this command multiple times.
terraform initThe terraform plan command is used to create an execution plan. Terraform performs a refresh, unless explicitly disabled, and then determines what actions are necessary to achieve the desired state specified in the configuration files.
Now that we're ready to create our resources, let's generate a plan file.
terraform plan -out=<terraform>.tfplanNow we can safely change our configuration files, and as long as we don't re-create our plan, we can be sure that this is all that's going to be applied.
Let's finally give that a go, run the following command:
terraform apply <terraform>.tfplanWe've now seen how to build and change infrastructure. You can cleanup the Terraform-managed infrastructure.
terraform destroy -force
