Following are brief descriptions of key concepts and the main components of Resource Manager.

CONFIGURATION

Information to codify your infrastructure. A Terraform configuration can be either a solution or a file that you write and upload.

JOB

Instructions to perform the actions defined in your configuration. Only one job at a time can run on a given stack; further, you can have only one set of Oracle Cloud Infrastructure resources on a given stack. To provision a different set of resources, you must create a separate stack and use a different configuration.

Resource Manager provides the following job types:

Plan: Parses your Terraform configuration and creates an execution plan for the associated stack. The execution plan lists the sequence of specific actions planned to provision your Oracle Cloud Infrastructure resources. The execution plan is handed off to the apply job, which then executes the instructions.

Apply. Applies the execution plan to the associated stack to create (or modify) your Oracle Cloud Infrastructure resources. Depending on the number and type of resources specified, a given apply job can take some time. You can check status while the job runs.

Destroy. Releases resources associated with a stack. Released resources are not deleted. For example, terminates a Compute instance controlled by a stack. The stack's job history and state remain after running a destroy job. You can monitor the status and review the results of a destroy job by inspecting the stack's log files.

Import State. Sets the provided Terraform state file as the current state of the stack. Use this job to migrate local Terraform environments to Resource Manager.

STACK

The collection of Oracle Cloud Infrastructure resources corresponding to a givenTerraform configuration. Each stack resides in the compartment you specify, in a single region; however, resources on a given stack can be deployed across multiple regions. AnOCIDis assigned to each stack.

the following steps reference Console instructions

Create a Terraform configuration.

Create a stack.

Run a plan job, which produces an execution plan.

Review the execution plan.

If changes are needed in the execution plan, update the configuration and run a plan job again.

Run an apply job to provision resources.

Review state file and log files, as needed.

You can optionally reapply your configuration, with or without making changes, by running an apply job again.

Optionally, to release the resources running on a stack, run a destroy job.
