Who Am I?

2008-2012 SRE in Higher Education and eCommerce.2012 SRE on Production Cloud Foundry2013 Engineer on BOSHOSCON 3rd time attending, 1st time speaking
What is BOSH?
A comprehensive service deployment tool.
Developed originally for Cloud Foundry.
Deploys distributed software onto various IaaS providers.
What BOSH is not
It is not a PaaS.
It is not Pacemaker, Clusterware, or other HA orchestration.
It is not clever.
Why BOSH?
Addresses the end-to-end problem of provisioning to running services.
Designed for updates, provisioning is just a side-effect.
Fast, predictable deploys that don't suffer from Configuration Drift.
Top Down Deployment Strategy
What do I want to deploy?
What services make it up?
How do those services run?
What software do they need?
Top Down Deployment Strategy
What do I want to deploy?A search indexer
What services make it up?Elastic Search
How do those services run?A Single Elastic Search process.
What software do they need?Java, Elastic Search
Job
Is a process or set of processes that can be configured and monitored.
What's the simplest thing I can monitor?
How about 'init'?
$ ps -efUID PID PPID C STIME TTY TIME CMD
root 1 0 0 09:10 ? 00:00:01 /sbin/init
root 2 0 0 09:10 ? 00:00:00 [kthreadd]
root 3 2 0 09:10 ? 00:00:01 [ksoftirqd/0]
root 5 2 0 09:10 ? 00:00:00 [kworker/0:0H]
root 7 2 0 09:10 ? 00:00:00 [kworker/u:0H]
root 8 2 0 09:10 ? 00:00:00 [migration/0]
Demo: Initial Release and Job
Deploy to a BOSH
What BOSH?
Deploy a BOSH
http://docs.cloudfoundry.com/docs/running/deploying-cf/
BOSH-Lite (VERY ALPHA)
https://github.com/cloudfoundry/bosh-lite
Come talk to us

Stemcell
A base OS image for deploying services on.
Currently an Ubuntu based image with an embedded BOSH Agent.
Knows how to discover location and can phone home.
Deployment Manifest
A description of a BOSH deployed release.
Describes What...
Release
Resources (Networks, Disks and VMs)
Services
Update behavior
Settings for the Release
Demo: Initial Deploy
What did that do?
Spun up a VM and monitored init.
This is where you think, 'Jolly good... who cares?'
Package
Source Based
Generates static files only, no templates
No pre/post apply scripts
Built on ephemeral VMs
Packaging script places files in $BOSH_INSTALL_TARGET
Demo: Adding Packages and Exploring an Instance
Demo: Updating a Service and Debugging
Properties
Variables that can be set at deployment time and used to configure jobs.
Can be scoped to single jobs or span multiple. Often to describe relationships (host / port to connect / listen to).
Demo: Introducing Properties
Scaling
Define the desired instances per job and BOSH will oblige.
Demo: Adding Instances
Rolling updates
Canary based deployments.
Tunable timeouts on expected update times.
Supports OS base image updates.
Supports rollback as separate deploy*
*if release version is backwards compatible (may require roll forward)
Demo: Rolling update
Infrastructures Supported
vSphere
vCloud
OpenStack
AWS
Experimental
CloudStack
Warden (LXC)
Demo: Taking it to a new Infrastructure
