Overview

Please be advised that this training may require Internet access for things such as downloading updates and Docker images.

The purpose of this training to to quickly demonstrate an application-centric IT architecture by providing an end-to-end solution for deploying containerized applications quickly and reliably, with atomic update and rollback for application and host alike.

We're going to be building 5 systems, one master and four hosts. These directions will produce the following systems:

hostname	ip	roles
atomic-master	192.168.122.10	cluster master, docker registry, ostree repository
atomic-host-01	192.168.122.11	atomic container host
atomic-host-02	192.168.122.12	atomic container host
atomic-host-03	192.168.122.13	atomic container host
atomic-host-04	192.168.122.14	atomic container host

Before You Arrive

In order to make best use of lab time, please review the deployment options and ensure you have one of the following:

1. A working KVM environment (preferred)
2. A working Virtual Box environment

Minimal time will be allocated during the training to get functional lab environments.

Notes, Comments and Pointers

• It is assumed that you will be utilizing Fedora Cloud Atomic
• Use sudo and appropriate permissions; insert standard security warnings here
• Correct IPs, hostnames, paths and locations to match your setup
• You will need to change the bridge device and/or adapter to match your setup

Downloads

We are going to be working with the Fedora Cloud Atomic image, however, this training should work with little to no modification on CentOS Atomic and Red Hat Enterprise Linux Atomic Host.

1. Fedora Atomic (preferred)
2. CentOS Atomic
3. Red Hat Enterprise Linux Atomic Host

The cloud-init images provided are basic and are not intended for use in a real world environment. Though not covered in this training, you should choose to customize the cloud-init image for instance: adding your own SSH public keys, changing the default password and setting other options as necessary.
