Terraform modules registry
Hello Everyone
Welcome to CloudAffaire and this is Debjeet.
In the last blog post, we have discussed terraform modules.
https://cloudaffaire.com/terraform-modules/
In this blog post, we will discuss terraform modules registry and will use terraform community-supported modules to create a vpc. Terraform has a enrich community that provides free modules for the general public. Instead of creating your own module from scratch, you can use these modules to deploy your infrastructure.
You can download terraform community supported modules for aws using below GitHub repository.
https://github.com/terraform-aws-modules
Prerequisite for this demo:
- AWS account with proper access
- Terraform and Git
Next, we are going to create a vpc using community supported terraform modules.
