Jenkins: Hub of Continuous Delivery

•  Connect the dots

•  It is the process


New Roles for Jenkins

•  Cross team plaiorm •  Deployment automaEon

–  App, dataset … environment provisioning •  Test automaEon: load test, acceptance test … •  Release management •  Workflow

Jenkins as an ApplicaEon Lifecycle Management plaiorm


Cross Team Platform

•  Not only used by DEV but also QA and OPS

•  Various profiles and skills

•  Mission CriEcal


Deployment Automation

•  Same tools and automaEons on all the environments

xxx Environment

xxx Environment

•  Deploy app, dataset … •  Plugins ecosystem


Test Automation

•  Powered by Jenkins ecosystem

•  Requires full environment setup (app, dataset)


Brian Marick


Release Management

•  Not only “mvn release:prepare release:perform”

•  Includes QA validaEon, Staging …

•  “Jenkins' Maven job type considered evil” S. Connolly


Workflow

Nightly Build

Unit Tests

Perfs Tests

Selenium Tests Deploy to UAT

Sonar Analysis


Workflow

Choreograph acEviEes that are … •  complex •  long-‐running •  not sequenEal •  pausable •  retryable


Workflow

Today

•  Build Flow Plugin

•  Build Pipeline Plugin

•  Build Delivery Pipeline


Workflow


Jenkins Workflow Plugin

•  Engine is Open Source •  Should become a de-‐facto standard for CD •  Groovy DSL •  1 single job to replace mulEple atomic jobs •  Intended for graphical visualizaEon and value-‐added extensions

•  SomeEmes in 2014


Great power, great responsibilities

Cross team collaboraEon plaiorm:

•  High Availability and SLAs

•  Security


High Availability and SLAs

•  Jumbo Jenkins masters are fragile –  MulEple medium sized Jenkins masters

•  Careful version upgrades –  TesEng environment + Jenkins & plugins version control

•  Support •  It’s not an open bar, security
