Static Assets Modules

This repo contains modules for managing static assets (CSS, JS, images) in AWS, including:

  • s3-static-website: Deploy static content (e.g. HTML, CSS, JS) in an S3 bucket.
  • s3-cloudfront: Deploy a CloudFront distribution as a CDN in front of an S3 bucket.

What is a module?

At Gruntwork, we've taken the thousands of hours we spent building infrastructure on AWS and condensed all that experience and code into pre-built packages or modules. Each module is a battle-tested, best-practices definition of a piece of infrastructure, such as a VPC, ECS cluster, or an Auto Scaling Group. Modules are versioned using Semantic Versioning to allow Gruntwork clients to keep up to date with the latest infrastructure best practices in a systematic way.

How do you use a module?

Most of our modules contain either:

  1. Terraform code
  2. Scripts & binaries

Using a Terraform Module

To use a module in your Terraform templates, create a module resource and set its source field to the Git URL of this repo. You should also set the ref parameter so you're fixed to a specific version of this repo, as the main branch may have backward incompatible changes (see module sources).

For example, to use v1.0.8 of the ecs-cluster module, you would add the following:

module "ecs_cluster" {
  source = "git::git@github.com:gruntwork-io/terraform-aws-ecs.git//modules/ecs-cluster?ref=v1.0.8"

  // set the parameters for the ECS cluster module
}

Note: the double slash (//) is intentional and required. It's part of Terraform's Git syntax (see module sources).

See the module's documentation and vars.tf file for all the parameters you can set. Run terraform get -update to pull the latest version of this module from this repo before runnin gthe standard terraform plan and terraform apply commands.

Using scripts & binaries

You can install the scripts and binaries in the modules folder of any repo using the Gruntwork Installer. For example, if the scripts you want to install are in the modules/ecs-scripts folder of the https://github.com/gruntwork-io/terraform-aws-ecs repo, you could install them as follows:

gruntwork-install --module-name "ecs-scripts" --repo "https://github.com/gruntwork-io/terraform-aws-ecs" --tag "0.0.1"

See the docs for each script & binary for detailed instructions on how to use them.

Developing a module

Versioning

We are following the principles of Semantic Versioning. During initial development, the major version is to 0 (e.g., 0.x.y), which indicates the code does not yet have a stable API. Once we hit 1.0.0, we will follow these rules:

  1. Increment the patch version for backwards-compatible bug fixes (e.g., v1.0.8 -> v1.0.9).
  2. Increment the minor version for new features that are backwards-compatible (e.g., v1.0.8 -> 1.1.0).
  3. Increment the major version for any backwards-incompatible changes (e.g. 1.0.8 -> 2.0.0).

The version is defined using Git tags. Use GitHub to create a release, which will have the effect of adding a git tag.
