This repository contains configurations for using Packer to build machine images that define a base Docker image, including AMIs (for AWS) and VirtualBox-based Vagrant boxes.

Boxes provisioned with these images will have the Docker engine running and ready to go as well as some base utilities and configurations that we find useful in all our environments.

This project attempts to create equivalent images across providers by starting from similar base images and applying the same provisioning steps using Ansible. This approach allows us to switch between AWS and Vagrant with little overhead and push common elements of Ansible-based deploys into the initial image to save time during deployment.

We are using Ubuntu Trusty 14.04 cloud images as our source AMI. To update to a newer version go to http://cloud-images.ubuntu.com/query/trusty/server/released.current.txt and find the 64-bit (amd64), ebs-ssd, hvm image in the us-west-2 region.

A shortcut to find the right AMI:

curl -s http://cloud-images.ubuntu.com/query/xenial/server/released.current.txt |grep ebs-ssd |grep amd64 |grep hvm |grep us-west-2 |cut -f8 -d$'\t'

Check http://releases.ubuntu.com for the latest 14.04 release and checksum.

We no longer support instance-store images as they are a pain. Use EBS.

Once your changes are merged to master Atlas will trigger a build automatically.

Once Atlas is done building you can find the latest images here:

• AWS AMIs
• Virtualbox Boxes

For an AMI, you can find it's id by looking at the metadata in Atlas.

This repo is using git subtrees to pull in dependencies. Why not submodules? Well, they're horrible for one. Subtrees are much simpler, you don't need to run any extra commands, just clone as usual and everything is there.

The vagrant image is heavily based on Chef's excellent work on their bento packer definitions. So much so that we use their scripts directly from our definitions.

To update the bento subtree:

git subtree pull --prefix bento https://github.com/chef/bento.git 2.2.2 --squash

Only use bento release tags when updating bento.
