more detailed examples

Better QA. There seems to be a lot of regressions.

Server recommendations Better uptime

Better UI.

Provide video tutorials.

Easily manage build jobs for different branches from a single configuration.

Introducing Jenkins Enterprise by CloudBees


Position Longer Term Support and Enterprise‐y Plugins

Benefit Fast issue resolutions & greatly improved management

Action evaluate (support){ // meets my organizational needs … } evaluate (plugins){ // makes my life easier … }



• In a nutshell – Subscription – Technical support + Value-add plugins

• Current Themes – For large installations – Security for enterprise – Optimized utilization

• Upcoming Themes – HA – Reporting

Jenkins Enterprise by CloudBees




Jenkins Enterprise Themes and Plugins

Large Installation

• Folders • Templates • Backup

Security

• Roles‐based Access Control

• Wikitext Descriptions

Optimized Utilization

• Auto‐scaling for VMWare installations

• Throttled Build Execution

• Even Load Strategy

• Skip Next Build



Jenkins LTS • Jenkins weekly too

often • Addressed by LTS

– ~ every 3 months

• If you are not on it…you should be!

JE by CloudBees • LTS supported for 9

additional months – Orgs can be on LTS for 1

year.

• Orgs get support on Jenkins and not on a proprietary release

Longer term support




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



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?



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 2

Idle



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



Skip Next Build



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



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



VMWare Plugin Improvements

• Jenkins will use all the machines in a vCenter folder



More improvements

• XML/JSON API support on VMWare objects

• Load statistics graph support • UUID-based more reliable machine

tracking


Demo: views in folders



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?



Template Plugin in a nutshell

• Actors – Admins: people who defines templates – Users: people who use templates


Demo: Hello World Builder



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



Demo: Hello World Job



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



More on templating

• Inheritance & composition Car

Going larger

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

• Verified component integration • Build pipeline • Workflow



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



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



CloudBees and Jenkins

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



CloudBees and Jenkins

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

• Jenkins Enterprise by CloudBees – Subscription – Technical support + Value-add plugins

Jenkins LTS • Jenkins weekly too

often • Addressed by LTS

– ~ every 3 months

• If you are not on it…you should be!

JE by CloudBees • LTS supported for 9

additional months – Orgs can be on LTS for 1

year. – Mitigating risks

• Orgs get support on Jenkins and not on a proprietary release – Mitigating risks

Long..er term support




• 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

Value-add Plugins



Demo



• Auto-scaling with VMWare ESXi/vCenter • New scheduler algorithm that prefers

more even loading • Hypervisor-aware build throttling • WikiText for XSS prevention • Backup

… and more
