Terraform module to create an ALB, default ALB listener(s), and a default ALB target and related security groups.
> [!TIP]
> #### 👽 Use Atmos with Terraform
> Cloud Posse uses [`atmos`](https://atmos.tools) to easily orchestrate multiple environments using Terraform.
> Works with [Github Actions](https://atmos.tools/integrations/github-actions/), [Atlantis](https://atmos.tools/integrations/atlantis), or [Spacelift](https://atmos.tools/integrations/spacelift).
>
>
> Watch demo of using Atmos with Terraform
> 
> Example of running atmos to manage infrastructure from our Quick Start tutorial.

## Usage
For a complete example, see [examples/complete](examples/complete).

> [!IMPORTANT]
> In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation
> and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version
> you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic
> approach for updating versions to avoid unexpected changes.
