This document discusses using SaltStack for seamless orchestration of virtual machines and Docker containers. It provides an overview of Bitfusion and SaltStack, and how SaltStack's event reactor system can be used to publish Docker events to the SaltStack event bus and react to those events with Salt states. This allows for autoconfiguration of environments and other capabilities. The presentation includes demos of enabling GPU-accelerated Docker containers with Bitfusion and SaltStack. It concludes by requesting feedback via the SaltConf16 event app.

2. Agenda
• Bitfusion Overview
• SaltStack & Container Orchestration
• Demos
• Q&A

4. Technology

5. Deployment

6. Seamless Orchestration of VMs and Docker
….beyond installing Docker Engine via SaltStack
Why not other solutions?
• Single Toolchain to manage both – mix Docker and VMs
• Tight integration with existing environment
• Docker tools don’t manage VMs well or at all
(Swarm, Compose, Kubernates etc.)
• VM tools aren’t good at very large pools of volatile containers
• Puppet - IP address keyed
• Chef - too complex
• Ansible - too simple
The Problem

7. SaltStack does it all!
• Deep integration with VMs (salt-cloud) and Docker (docker-ng)
• Good at highly volatile environments
• Intelligent Datacenter Management with Reactor
The Solution

8. Docker has an event (SSE) stream
SaltStack has Event Reactors
Publish Docker events on SaltStack event bus!
React to Docker events with Salt States!
Autoconfigure environments!
Publish notifications!
… do other cool stuff!

9. Docker backends
• Has multiple “graph driver” backends
• Use OverlayFS, fast, efficient but needs lots of iNodes
What we use:
• Saltstack Master + Minion: 2015.8.8.2
• Docker: 1.10.1+
• Ubuntu: 14.04LTS
• Build AMIs with Packer and Saltstack Provisioner
Getting setup…
