Dead simple Terraform configuration for creating RabbitMQ cluster on AWS.

What it does ?

1. Uses official RabbitMQ docker image.
2. Creates Autoscaling Group and ELB to load balance nodes
3. Configures / vhost queues in High Available (Mirrored) mode with automatic synchronization ("ha-mode":"all", "ha-sync-mode":"3")
4. uses the aws peer discorvery for cluster creation
5. removes old nodes from the cluster and rebalances quorum queues when a new node joins the cluster
6. the names of the various resources is formed by ${name_prefix}-${resource_abreviation}-${region}-${name_postfix}, thereby allowing you to conform to the naming scheme. The prefix should contain prefix, project and env. The postfix should contain description and suffix.

How to use it ?

The following configuration options exist:

module "rabbitmq" {
  name_prefix                       = ""
  name_postfix                      = ""
  source                            = "github.com/Patagona/terraform-aws-rabbitmq?ref=001055c"

  ssh_key_name                      = ""
  subnet_ids                        = [""]
  elb_additional_security_group_ids = [""]
  size                              = "3"
  service_tag                       = ""
  instance_type                     = "t3a.micro"

  instance_volume_size              = "10"
  instance_volume_iops              = "3000"
  instance_volume_throughput        = "125"
  metric_host                       = "" # the hostname, where metrbicbeat publishes metrics to
  metricbeat_version                = "7.17.1" # defaults to "7.17.1"
