Publishing Terraform modules

We have already learned how to publish Terraform modules to a GitHub repository specific to your project. How about if you want to contribute to the Terraform community? For that, HashiCorp provides you with an option of publishing your well-written code to Terraform Registry.

Anyone can write a module and get it published to Terraform Registry. Terraform Registry supports versioning and generates documentation, and you can even browse all the version history. Always remember to try to write more generic modules so that they are reusable. All the published public modules are managed through Git and GitHub. Writing and publishing a module is very easy and doesn't take much time; once a module gets published, you can get it updated by pushing the updated code with the respective Git tag following proper semantic versioning (that is, either v1.03 or 0.6.0).
