Terraform Provider Version Conflicts When Using Multiple Modules with AWS Resources
I'm prototyping a solution and I'm refactoring my project and I'm trying to figure out I've searched everywhere and can't find a clear answer. Hey everyone, I'm running into an issue that's driving me crazy. I'm experiencing issues with Terraform when trying to use multiple modules that rely on different versions of the AWS provider. Specifically, I have a main module that uses `terraform-aws-modules/vpc/aws` version `2.0.0`, and a separate module for EC2 instances that uses `terraform-aws-modules/ec2-instance/aws` version `3.0.0`. When I run `terraform init`, I get the following behavior: ``` behavior: Failed to install provider "hashicorp/aws" (version "~> 2.0"): version constraints for hashicorp/aws conflict with dependency requirements of another module e The required provider version is incompatible with the provider requirements defined in the dependency. ``` I've tried pinning the AWS provider version in my main `main.tf` file as well: ```hcl terraform { required_providers { aws = { source = "hashicorp/aws" version = "~> 2.0" } } required_version = ">= 0.12" } ``` However, it seems that it's still causing conflicts. I also attempted to consolidate the provider versions across my modules by updating the EC2 instance module to also use version `2.0.0`, but that caused compatibility issues with other features I need in the EC2 module such as user data scripts and CloudWatch integration, which only work well with version `3.x`. I'm unsure how to effectively manage these version conflicts without significantly altering my resources' configurations or functionality. Is there a recommended approach or best practice for handling provider versioning when working with multiple modules in Terraform? Should I consider refactoring my modules, or is there a way to allow different versions to coexist safely? My development environment is macOS. Any help would be greatly appreciated! This is part of a larger web app I'm building. This is my first time working with Hcl LTS. Am I approaching this the right way? I'm working with Hcl in a Docker container on Linux. Could someone point me to the right documentation? I'm working on a application that needs to handle this.
