These resources cover the core Terraform workflow (Objective #6).

Learn more subcommands

The Terraform CLI includes subcommands for operations beyond the core workflow, including importing resources and manipulating and inspecting state. Review the following resources and tutorials to get more familiar with the Terraform CLI.

• Command: state documentation
• Manage Resources in Terraform State tutorial
• Command: import documentation
• Import usage tips documentation
• Debugging Terraform documentation
• Troubleshoot Terraform tutorial

These resources cover the Terraform CLI outside of the core workflow (Objective #4).

Use and create modules

Modules help you organize and re-use Terraform configuration. Complete the Modules tutorials to learn more about modules, including how to reference modules from the Terraform registry and create your own.

• Reuse Configuration with Modules (complete all tutorials)

Review these additional resources to learn about modules and associated concepts in more depth.

• Finding and Using Modules documentation
