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

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

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!

The Saltstack Event System

Master

Event

Reactor

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
