Extending Terraform with Plugins: A Step-by-Step Guide

Introduction

To extend Terraform with plugins, you can use Provider Plugins or Provisioner Plugins. Here's a step-by-step guide on how to extend Terraform with plugins:

Understand the Types of Plugins

  • Provider Plugins: These extend Terraform's capabilities to work with cloud providers and services. Provider plugins define and implement resource types and manage the underlying API interactions.
  • Provisioner Plugins: These extend Terraform's capabilities to execute actions on newly created or existing resources, such as running scripts, configuring software, etc.

Write Your Plugin Code

  • Provider Plugin: Implement the required provider interface, which includes defining the resources and the CRUD operations (create, read, update, and delete) for each resource type.
  • Provisioner Plugin: Implement the provisioner interface, defining the actions to be taken on the resources.

Build the Plugin Binaries

  • For Provider Plugins: Build the plugin binary using your preferred programming language, following the specific guidelines of the provider you are targeting.
  • For Provisioner Plugins: Build the plugin binary using your preferred programming language, following Terraform's provisioner plugin documentation.

Install the Plugin

  • Provider Plugin: Install the provider plugin binary as an executable and set the appropriate configuration in the Terraform configuration files or environment variables.
  • Provisioner Plugin: Install the provisioner plugin binary as an executable and ensure it is available in the system PATH.

Update Your Terraform Configuration

  • For Provider Plugins: Declare the provider block with the necessary configuration parameters in your Terraform configuration file (e.g., provider.tf).
  • For Provisioner Plugins: Use the provisioner attribute within the resource blocks, specifying the plugin name and configuration parameters.

Initialize Terraform

  • Run the terraform init command in your project directory to initialize Terraform and make it aware of the newly installed plugin.

Use the Plugin

  • With the Provider Plugin: You can now leverage the extended resources and capabilities within your Terraform configuration files.
  • With the Provisioner Plugin: The specified actions will be executed on the respective resources during the Terraform lifecycle.

Conclusion

By following these steps, you can extend Terraform's functionality through the use of plugins, enabling you to work with a wider range of cloud providers or execute custom actions on resources.
