Nomad for Terraform

This module deploys an entire Nomad/Consul cluster, with minimal configuration.

The module can deploy both masters and slaves, in one call, or can be used to deploy them separately.

The module also includes support for AWS Elastic Container Registry (ECR), and will automatically get credentials for the slave nodes.

Example:

module "nomad" {
  source = "[email protected]:patch-notes/terraform-nomad.git"
  num_masters = 1
  num_slaves = 1
  availability_zones = ["eu-central-1a", "eu-central-1b"]
  master_instance_type = "t2.micro"
  cidr_vpc = "10.0.0.0/16"
  cidr_masters = "10.0.0.0/24"
  cidrs_slaves = ["10.0.1.0/24", "10.0.2.0/24"]
  key_name = "main"
  slave_target_group_arns = ["${aws_lb_target_group.gateway.arn}"]
  slave_instance_type = "t2.micro"
}
