1. Automate jenkins job creation Toni Van de Voorde – CTO @ Adsdaq.eu
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
