Concourse Packer

A packer template and associated resources for creating an AMI that runs a standalone Concourse installation suitable for bootstrapping more complex infrastructure.

Setup

To build an AMI with this template first create a secrets.json file with the following contents:

{
	"aws_access_key": "your-aws-access-key",
	"aws_secret_key": "your-aws-secret-key",
	"aws_region": "us-gov-west-1"
}

If deploying to a region other than us-east-1 add the the source_ami key to the secrets with the appropriate AMI-ID for the region. According to the Concourse installation guide only Ubuntu 14.04 LTS is supported.

AMI-IDs for other regions can be found by using Ubuntu's AMI locator and selecting the 14.04 LTS hvm:ebs-ssd image for the desired region.

Building

Once a secrets file has been created created, the AMI can be built with the following command:

packer build -var-file=secrets.json bootstrap_concourse.json

Once the process finishes a new AMI will be ready for use in the selected region.

Using

Setting credentials

The AMI created by this template supports setting the concourse basic-auth username and password via user-data when the instance is boooted.

This is done by providing a simple YAML document that contains username and password keys as the instance's user-data. The hostname key is optional, but if set will be passed as external-url to concourse. If hostname is not provided, then the public-hostname from the metadata service will be used

# This is a sample YAML file that will configure the concourse username and password

username: admin
password: swordfish
hostname: ci.example.com

Accessing Concourse

Concourse runs on port 443. Ensure the instance is placed into a security group that allows access to this port.
