  26. © 2016 CloudBees, Inc. All Rights Reserved Overwhelmed by Jenkins?

    Me too. Dear Mr Jenkins, There are too many plugins these days. Please eliminate three hundred. P.S. I am not a crackpot. 26
  27. © 2016 CloudBees, Inc. All Rights Reserved Initial Experience is

    Complicated • Installing Jenkins? That’s easy. – But then there’s finding the right plugins… – And setting up security… – And eighty other things you probably forgot about… •That should be easier !! 27
  28. © 2016 CloudBees, Inc. All Rights Reserved Continuous Delivery of

    All the Things • Continuous Delivery is eating the software that is eating the world. • More shops moving in this direction. • Jenkins is a key part of how they get there. • New use cases need new user interfaces - one size doesn’t always fit all. • How can we make adopting Jenkins for CD smoother without limiting the power Jenkins has for other use cases? 28
  29. © 2016 CloudBees, Inc. All Rights Reserved How do I…where

    do I…what do I… • jenkins-ci.orgsite is 6 years old, give or take. – Old tooling. – Awkward content discovery. – Not a great way to share documentation and guides. – wiki.jenkins-ci.org is there too, but it’s not easy to navigate. • Brand – jenkins-ci.org ! CI ?!? o Jenkins isn’t only a CI. 29

  33. © 2016 CloudBees, Inc. All Rights Reserved Pipeline as Code

    • Introduce “pipeline” as a new type in Jenkins • Codify an implicit series of stages into an explicit Jenkinsfile in your source repository or directly in your job definition • Built-in global library to share Pipeline scripts, functions, variables across jobs on your master. • Extend the DSL with your own steps. • Multibranch, automatic creation of jobs for new branches! • Durable tasks keep running while the Jenkins master restarts. 33
  34. © 2016 CloudBees, Inc. All Rights Reserved Pipeline as Code

    • Resumability from checkpoints (CloudBees Jenkins Platform only) • Execute arbitrary build steps in parallel easily. • Have jobs wait for input from users before continuing to the next step. • No more need to glue multiple jobs together to do one connected pipeline across multiple nodes or repos! • Run part of the job on one node, then switch to another node! • Check out multiple SCM repositories into one job! 34

    is this part of the 2.0 release? Can’t you just update the website whenever? • Sure, but like we said, the changes we’re making to the website are to address a lot of the things 2.0 proper is addressing: – On-boarding – Plugin discovery – Documentation – Examples and resources Website as part of release? 59 59
  60. © 2016 CloudBees, Inc. All Rights Reserved New website: the

    guts • Current website – Drupal – Dynamically generated – Hard to contribute to - gotta get an account, submit a blog post, etc… • New website – Static site generation – Awestruct and Asciidoc – Contributing? Just submit a pull request to https://github.com/jenkins-infra/jenkins.io and tada! 60
  61. © 2016 CloudBees, Inc. All Rights Reserved Better home for

    documentation and reference • What we’re calling “Solutions Pages” – Landing pages for collections of docs, blog posts, reference material and advice for specific Jenkins use cases. – i.e., a Ruby solution page, a Docker solution page, etc • A one-stop-shop for finding what you *need* to know for your Jenkins usage. • SOON: The Jenkins definitive guide, a real browsable end- user documentation 61

    Inc. All Rights Reserved Conclusion
  84. © 2016 CloudBees, Inc. All Rights Reserved • Jenkins 2.0

    is a new start for the community. • But 2.0 is just a drop-in replacement for 1.x – With the exception of the servlet 3.1 (Java EE 7) container pre-requisite (Apache Tomcat 8, Wildfly 8, Glassfish 4, Websphere 9...) • All the technical evolutions (like javascript modularization) are in place to revolution Jenkins in a near future. • The usage of major versions is a good change which will enforce to identify and accept breaking changes to – define a clearer roadmap for users ( 3.x, 4.x, …. ) – organize this middle/long term work within the team Conclusion 84

    2.0 now! • Jenkins 2.0 Final will be out in 2 weeks !! • Downloadand discover it from – jenkins.io / jenkins-ci.org/2.0 • Test alpha/beta/rc releases and share your feedback with the community – jenkinsci-users@googlegroups.com – #jenkins IRC channel on Freenode • Come to discuss with us at the CloudBees booth @BreizhCamp 85
