How to Create and Use a Custom Provider in Terraform

In this tutorial, we learned how to create a custom provider plugin for Terraform using Go programming language. We implemented two data sources and one resource in the process. The steps involved are as follows: 1. Setting up the development environment by installing necessary tools like Go, AWS CLI, and Terraform. 2. Initializing the project with a basic plugin template provided by HashiCorp. 3. Implementing the data source for listing all existing S3 buckets in an AWS account. 4. Testing the data source implementation using a separate Terraform configuration file. 5. Implementing the resource for creating new S3 buckets with tags and other configurations. 6. Testing the resource implementation by applying changes to the Terraform configuration files. 7. Verifying the plugin functionality by observing real-time AWS resources being created, updated, or destroyed based on the Terraform commands executed. This tutorial provided a basic understanding of custom provider plugin development for HashiCorp's Terraform using Go programming language. It can be extended further to include more complex use cases and features as per specific requirements.
