terraform-aws-mq-broker

Terraform module to provision AmazonMQ resources on AWS

This project is part of our comprehensive "SweetOps" approach towards DevOps.

It's 100% Open Source and licensed under the APACHE2.

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!

Introduction

This module provisions the following resources:

ActiveMQ broker
RabbitMQ broker
Security group rules to allow access to the broker

Admin and application users are created and credentials written to SSM if not passed in as variables.

Security & Compliance

Security scanning is graciously provided by Bridgecrew. Bridgecrew is the leading fully hosted, cloud-native solution providing continuous Terraform security and compliance.

Usage

IMPORTANT: We do not pin modules to versions in our examples because of the difficulty of keeping the versions in the documentation in sync with the latest released versions. We highly recommend that in your code you pin the version to the exact version you are using so that your infrastructure remains stable, and update versions in a systematic way so that they do not catch you by surprise.

Also, because of a bug in the Terraform registry (hashicorp/terraform#21417), the registry shows many of our inputs as required when in fact they are optional. The table below correctly indicates which inputs are required.

For a complete example, see examples/complete.

For automated tests of the complete example using bats and Terratest (which tests and deploys the example on AWS), see test.

  module "mq_broker" {
    source = "cloudposse/mq-broker/aws"
    # Cloud Posse recommends pinning every module to a specific version
    # version     = "x.x.x"
