AWS Autoscaling Terraform Module -

This is an opinionated and simplified Autoscaling module for AWS. This module automatically creates an Autoscaling Group and an Autoscaling Launch Configuration.

Usage

provider "aws" {
  version = "~> 1.0.0"
  region  = "eu-west-1"
}

# Add our autoscaler
module "autoscaler" {
    source             = "github.com/olindata/terraform-aws-ezvpc.git"
    name               = "widgets-webservers"
    subnet_ids         = ["subnet-12312312", "subnet-23423423"]  # Put your private subnet IDs here, maybe from our
    image_id           = "ami-12312312"                          # (optional, put premade AMI here, defaults to latest ubuntu)
    is_live            = false                                   # (optional, default false) Set to true for Multi-AZ and advanced monitoring
    instance_type      = "${var.instance_type}"                  # (optional, default db.t2.nano) Set the instance type
    security_groups    = ["${aws_security_group.default.id}"]    # (optional) Add security group ids to the instances
    user_data          = ""                                      # (optional, put userdata scripts here)
}

# WARNING: In the above example, you should be using our terraform-tags
# module from https://github.com/olindata/terraform-tags instead of
# hardcoding tags like this bad example.  Please see examples in our
# templates folder of our terraform-aws repository.

This module does the following...

• Creates an AWS Autoscaling Group
• Creates an AWS Autoscaling Launch Configuration

Module created and managed by Farley and OlinData

Todo list

• Add CloudWatch Alarms to scale up/down based on CPU Load (possibly Farley's Multi-model scaling approach)
