2. Why Jenkins ? o Free o Open-Source o Customization o

   Plugin system o Full control of the system

3. But o Time needed for configurations / customization

4. Adsdaq o Microservice oriented o Different techno's o Lot’s of

   small feature branches Many jobs to manage !!!

5. The solution Job DSL Plugin

6. Job DSL Plugin A groovy-based Domain Specific Language for Jenkins

   Jobs

7. Job DSL Plugin Installation FROM jenkins/jenkins:lts-alpine RUN /usr/local/bin/install-plugins.sh job-dsl

8. Job DSL Plugin Configuration 1. Create new Freestyle project

9. Job DSL Plugin Configuration 2. Add SCM

10. Job DSL Plugin Configuration 3. Add build step

11. Job DSL Plugin Configuration 4. Configure the build step

12. Job DSL Plugin Configuration 5. Save and execute the job

13. Job DSL Plugin Script Security Your first execution failed right

    ??? o Script Approval o Sandboxing o Disable

14. Job DSL Plugin Script Security Script Approval

15. Job DSL Plugin def gitUrl = 'git://github.com/jenkinsci/job-dsl-plugin.git’ job('demo1') { scm

    { git(gitUrl) } triggers { scm('*/15 * * * *') } steps { maven('-e clean test') } } Example demo1.groovy

16. Job DSL Plugin def gitUrl = 'git://github.com/jenkinsci/job-dsl-plugin.git’ job('demo1') { scm

    { git(gitUrl) } triggers { scm('*/15 * * * *') } steps { maven('-e clean test') } } Example demo1.groovy

17. Job DSL Plugin def gitUrl = 'git://github.com/jenkinsci/job-dsl-plugin.git’ job('demo1') { scm

    { git(gitUrl) } triggers { scm('*/15 * * * *') } steps { maven('-e clean test') } } Example demo1.groovy

18. Job DSL Plugin def gitUrl = 'git://github.com/jenkinsci/job-dsl-plugin.git’ job('demo1') { scm

    { git(gitUrl) } triggers { scm('*/15 * * * *') } steps { maven('-e clean test') } } Example demo1.groovy

19. Job DSL Plugin def gitUrl = 'git://github.com/jenkinsci/job-dsl-plugin.git’ job('demo1') { scm

    { git(gitUrl) } triggers { scm('*/15 * * * *') } steps { maven('-e clean test') } } Example demo1.groovy

20. Job DSL Plugin Currently supports up to 190 Plugins

21. Job DSL Plugin Community Driven o > 1000 Pull Requests

    o 155 contributors o > 1000 stars

22. Job DSL Plugin Extend the DSL Heeelp my plugin is

    not (yet) supported

23. Job DSL Plugin Extend the DSL demo2.groovy

24. Job DSL Plugin Generate Jobs/branch (1) demo3.groovy def gitUrl =

    'git://github.com/jenkinsci/job-dsl-plugin.git’ def branches = ['master','dev','hotfix'] branches.each { branch -> job("demo3-${branch}") { scm { git(gitUrl, branch) } } }

25. Job DSL Plugin Generate Jobs/branch (1) demo3.groovy def gitUrl =

    'git://github.com/jenkinsci/job-dsl-plugin.git’ def branches = ['master','dev','hotfix'] branches.each { branch -> job("demo3-${branch}") { scm { git(gitUrl, branch) } } }

26. Job DSL Plugin Generate Jobs/branch (1) demo3.groovy def gitUrl =

    'git://github.com/jenkinsci/job-dsl-plugin.git’ def branches = ['master','dev','hotfix'] branches.each { branch -> job("demo3-${branch}") { scm { git(gitUrl, branch) } } }

27. Job DSL Plugin Generate Jobs/branch (2) demo4.groovy def project =

    'Netflix/asgard’ def branchApi = new URL("https://api.github.com/repos/${project}/branches") def branches = new groovy.json.JsonSlurper().parse(branchApi.newReader()) branches.each { def branchName = it.name def jobName = "${project}-${branchName}".replaceAll('/','-') job(jobName) { scm { git("https://github.com/${project}.git", branchName) } } }

28. Job DSL Plugin Generate Jobs/branch (3) demo5.groovy def project =

    'automate-jenkins-job-creation’ def repo = "https://tonivdv@bitbucket.org/tonivdv/${project}.git" Process proc1 = "git ls-remote -h ${repo}".execute() Process proc2 = 'sed s/.*refs\\/heads\\///g'.execute() Process all = proc1 | proc2 all.waitFor() def branches = "${all.in.text}".split('\\n') branches.each { … }

29. Job DSL Plugin Generate Jobs/branch (4) demo5bis.groovy package utilities public

    class GitUtils { public static String[] getRemoteBranches(def repoUrl, def out) { Process proc1 = "git ls-remote -h ${repoUrl}".execute() Process proc2 = 'sed s/.*refs\\/heads\\///g'.execute() Process all = proc1 | proc2 all.waitFor() out.println "### DEBUG: Begin ###" ... out.println "### DEBUG: End ###" def branches = "${all.in.text}".split('\\n') return branches } }

30. Job DSL Plugin Generate Jobs/branch (5) demo5bis.groovy import utilities.GitUtils def

    project = 'automate-jenkins-job-creation’ def repo = https://tonivdv@bitbucket.org/tonivdv/${project}.git def branches = GitUtils.getRemoteBranches(repo, out) folder('demo5bis') branches.each { … }

31. Job DSL Plugin Conditionals demo6.groovy branches.each { branch -> def

    myjob = job(jobName) { .. } if (branch == "master") { myjob.with { steps { maven('-e deploy clean test') } } } else { ... } }

32. Job DSL Plugin Conditionals demo6.groovy branches.each { branch -> def

    myjob = job(jobName) { .. } if (branch == "master") { myjob.with { steps { maven('-e deploy clean test') } } } else { ... } }

33. Job DSL Plugin Conditionals demo6.groovy branches.each { branch -> def

    myjob = job(jobName) { .. } if (branch == "master") { myjob.with { steps { maven('-e deploy clean test') } } } else { ... } }

34. Job DSL Plugin Many other features o Use any Java/Groovy

    libraries o Functions to reuse code o Create Views/Folders/Worflows/…

35. Job DSL Plugin Tips o Credential Plugin o JobConfigHistory Plugin

    o Use the great API Viewer o (https://[jenkins-host]/plugin/job-dsl/api-viewer/index.html) o https://jenkinsci.github.io/job-dsl-plugin/

36. Job DSL Plugin Tips o Commit your DSL scripts to

    SCM o Don’t create jobs manually anymore :p

37. Job DSL Plugin References o Wiki o https://github.com/jenkinsci/job-dsl-plugin/wiki o API

    Viewer o https://jenkinsci.github.io/job-dsl-plugin/ o Presentation demo files o https://github.com/tonivdv/automate-jenkins-job-creation
