terraform-amazon-ecs's Introduction

Terraform AWS ECS (+ Docker Registry)

Note - This is still a work in progress, so expect issues and bugs .. Feel free to jump in and start fixing things.

This repo contains a Terraform plan to run up an Amazon ECS cluster with a private Docker registry.

Inspired from http://blog.codeship.com/running-a-private-docker-registry-on-ec2/

Includes -

Private S3 bucket for container registry data
Docker container running allingeek/registry:2-s3 (by default)
ECS cluster, launch configuration and autoscaling group

### Prerequisites

Terraform installed, recommended (>= 0.6.3). Head on over to https://www.terraform.io/downloads.html to grab the latest version.
An AWS account http://aws.amazon.com/

### Usage

Clone the repo
Set some required variables -

export TF_VAR_key_name=name of ssh key
export TF_VAR_key_file=the ssh key file to use
export TF_VAR_aws_access_key=The AWS access key ID
export TF_VAR_aws_secret_key=The AWS secret key

Run the plan -

terraform apply

Alternatively the variables can be passed on the command line e.g. -

terraform apply -var 'key_name=name' -var 'key_file=path_to_file' -var 'aws_access_key=access_key' -var 'aws_secret_key=secret_key'

For a full list of overridable variables see variables.tf

### Known issues

If you are using terraform v0.6.3 and encounter this error -

* aws_ecs_service.s3-registry-elb: InvalidParameterException: Unable to assume role and validate the listeners configured on your load balancer.  Please verify the role being passed has the proper permissions.
  status code: 400, request id: []

This is probably down to this bug / issue with waits/timeouts - hashicorp/terraform#2869.

You can either compile terraform from the latest master branch, or re-run the terraform apply again which should succeed the second time.
