I am writing this down so I don't forget. I started this task but had to stop a few times, and then remember where I left off and at some point, others will need to know how to get started.

Immutable DC/OS CentOS AMI image creator using docker
We created a packer AMI builder based on the advanced DC/OS install guide support for CentOS7. We use the official CentOS7 AMIs as a base.
Download and install packer.
$ brew install packer

Using CloudFormation, Packr, etc. for Immutable Infrastructure to build DC/OS and deploy it to Amazon Web Services
We setup a dev env for DC/OS in AWS (subnets, multi-az, ags groups, ami images, etc), tagged everything as dcos-dev, and then used Cloudformer to generate a starter AWS CloudFormation script. Cloudformer allows you to reverse engineer your AWS environment into cloudformation scripts. We then modified what cloudformer produced (to make it work as cloudformer just gets you about 90% of the way there), and then we added mappings, parameters and outputs to our cloudformation script.
Included are the cloudformation and packer scripts. Hope it helps you get setup. Feedback is welcome.
We in this case is my client, DC/OS support, Amazon support, and I. We did this instead of using the canned Amazon support because we needed to run masters, and agents in [multiple AZs](http://docs.aws.amazon.co

Setting up aws log agent to send journalctl from DC/OS logs to Amazon Log Service
In this example, we are using Centos7, journalctl and systemctl so that we can monitor logs from DC/OS instances (masters, agents and public agents). It is useful for anyone using systemd, journald in an AWS EC2 enviroment that wants logging. The nice thing about Amazon CloudWatch is that it integrates well with Amazon EMR and Amazon Elasticsearch. (For more background on this subject see this article which covers using CloudFormation, Packr, etc. for Immutable Infrastructure to build DC/OS and deploy it to Amazon Web Services.)
We will install journald-cloudwatch-logs. We are going to setup a daemon into systemd that forwards logs to Amazon CloudWatch log streams.
