Longer term support
Jenkins LTS JE by CloudBees
• Jenkins weekly too • LTS supported for 9
often additional months
• Addressed by LTS – Orgs can be on LTS for 1
year.
– ~ every 3 months
• If you are not on it…you • Orgs get support on
should be! Jenkins and not on a
proprietary release

Jenkins Enterprise = LTS + plugins
• No forked codebase
– All changes pushed to upstream now
– You can move between main line, LTS, and
JE without a loss

• Version number reflects this

1.424.1.1
Reserved

Using CloudBees plugins on OSS Jenkins
• If you want to stay on the mainline for
new features, that’d be fine with us!

• Install CloudBees update center as 2nd
update center
– 1.437 or later required
– Run a script* from Groovy Console

* https://raw.github.com/cloudbees/ride‐jenkins/master/ride‐jenkins.groovy

What’s new in 2011.10?

Reserved

Even load scheduler
• Jenkins assigns jobs to where it run
before
– Many reasons to do this: SCM checkouts,
warm local cache (Maven/ivy/gems)
• But this can create uneven load
Slave 1 Slave 2
Busy Idle
Busy Idle
Idle Idle

Reserved

Even load scheduler
• With this plugin…
– per job or as global default

• Use this when builds aren’t sticky
– If you are doing full checkout anyway
– Storage is network mounted

Reserved

Skip Next Build

Reserved

Skip Next Build
• Use this when…
– Large refactoring with instability
– External test resources offline for
maintenance

• Similar to “disabled build” in effect but it’ll
come back to normal automatically

Reserved

Recap: VMWare plugin
• ESXi or vCenter
• Auto-scaling
– Launches/stops VMs based on load
– Automatic IP detection on boot
• Snapshot/restore handling
– Helps you maintain clean slaves

Reserved

VMWare Plugin Improvements
• Jenkins will use all the
machines in a vCenter
folder

Reserved

More improvements
• XML/JSON API support on VMWare
objects
• Load statistics graph support
• UUID-based more reliable machine
tracking

Reserved

Demo: views in folders

Reserved

Template Plugin
• Ever had a lot of jobs that look similar?
– Changing them all is painful

• Ever wanted to “lock down” the job
setting so that devs only modify a few
things?

Reserved

Template Plugin in a nutshell
• Actors
– Admins: people who defines templates
– Users: people who use templates

Reserved

Demo: Hello World Builder

Reserved

Benefits
• Templates appear as 1st class citizen
– Almost the same result as writing a custom
plugin
• It speaks the terms users understand
– A lot more approachable for busy developers
• Updating is lot less painful

More on templating
• Programmability in transformation
– Via Groovy Server Page or Jelly
– Conditionals, loops, function calls, …

• Models are portable
– You can define it once, deploy elsewhere

Going larger
• Large scale automation beyond simple
build/test/report
– Caveat: not everything is fully cooked

• Verified component integration
• Build pipeline
• Workflow

Reserved

Going smaller
• Let developers use Jenkins for doing
their private builds
• Validated merge
– Prevent a developer error from appearing in
the trunk
– AKA pre-tested commit

Reserved

Extensibility
• Many pluggable/extensible aspects
– Proof is in the # of plugins
• Full lifecycle assistance to plugin
development
– Including assistance in IDE
– From skeleton to release
• Reasonable documentation
⇒ resulted in large number of
in‐house custom plugins

Jenkins as a platform
• Extensibility enables Jenkins to be a
building block for in-house tool
integration
• Many available APIs
– HTTP REST, CLI, Java inter-process
remoting
• Example
– IOS build with Jenkins here at Cisco
– Janky by GitHub

Reserved

CloudBees and Jenkins
• Sponsors OSS Jenkins development
• Provides other resources
– Sponsored Jenkins User Conference
– Bug bounty program
– Fund via donation to SPI

Reserved

CloudBees and Jenkins
• DEV@cloud
– Hosted Jenkins, utility pricing model
– Simplify deployment and administration
– Subscription

Value-add Plugins
• Hierarchical Folders
– Organize jobs into a tree structure
– Simple security enforcement
• Role-based Access Control
– Split access control from job configuration
– Work with indifferent IT ops
• Templates
– Make your Jenkins “speak” org-specific
terms and build processes

… and more
• Auto-scaling with VMWare ESXi/vCenter
• New scheduler algorithm that prefers
more even loading
• Hypervisor-aware build throttling
• WikiText for XSS prevention
• Backup
