Consul Image

Packer template for generating an AMI running Hashicorp's Consul.

Specifically, the template builds an AMI based on the Ubuntu 16.04 base image that runs a Consul server instance.

Using the Image

Requirements

The created image requires additional configuration in order to run. Notably:

• The bootstrap_expect or bootstrap parameter must be set.
• To listen on addresses other than localhost, the client_addr parameter must be set.

To accomplish this, create a file in the /opt/consul/config directory with the desired options. One solution for this is to use the user data parameters available when launching an EC2 instance.

Usage with Terraform

This repository is configured to create an image named consul-server-<consul version>-<timestamp>. This can be used in Terraform through the following:

data "aws_ami" "consul-server" {
    most_recent = true
    owner       = ["self"]

    filter {
        name   = "name"
        values = ["consul-server-*"]
    }
}
