terraform-ddc-aws

Terraform scripts to build a Docker Datacenter cluster on AWS

Currently provides:

• a security group
• Centos 7 instances for managers and workers

Usage

The scripts use default credentials management for AWS, most likely in ~/.aws/credentials, see the Terraform docs or this AWS blog post for more details

You need to define the following variables:

• aws_region: defaults to us-east-1
• key_name: the name of an existing key-pair
• public_key: the public key

There are more variables you can define, look in variables.tf

After terraform apply, get terraform output will give you the info needed to feed https://github.com/adrahon/ansible-docker-ucp

Customization

The easiest way to change some of the parameters is to add a override.tf file. For example, to change the AMI used it would have this content:

resource "aws_instance" "ucp-manager" {
  ami           = "ami-e8f9f28e"
}

resource "aws_instance" "ucp-dtr" {
  ami           = "ami-e8f9f28e"
}

resource "aws_instance" "ucp-worker" {
  ami           = "ami-e8f9f28e"
}
