12. ©2014 CloudBees, Inc. All Rights Reserved What we need • Complex pipelines involving mul9ple stages • Non-‐sequen$al logic such as loops, forks … • Long-‐running builds must survive outages • Interac$ons with humans including pauses, input • Restartable builds in case of transient errors • Reusable defini$ons to avoid duplica9on • Comprehensible scripts with one clear defini9on

15. Build Flow Plugin • Did have scriptability and extensibility ©2014 CloudBees, Inc. All Rights Reserved • Did not address configura9on “sprawl” • Disjointed view of what really ran • No ability to survive restarts • Almost good enough but could not go further

21. ©2014 CloudBees, Inc. All Rights Reserved Key features • En9re flow is one concise Groovy script – For loops, try-‐finally, fork-‐join … • Can restart Jenkins while flow is running • Allocate slave nodes and workspaces – As many as you want, when you want • Stages throYle concurrency of builds • Human input/approval integrated into flow • Standard project concepts: SCM, ar9facts, plugins

22. Groovy DSL vs. Graphical Workflow • Familiar control flow construc9on ©2014 CloudBees, Inc. All Rights Reserved • Familiar “tools” for building abstrac9ons Func9ons, classes, variables, … • Workflow in version control • As opposed to: Graphical workflow designer

23. ©2014 CloudBees, Inc. All Rights Reserved Project setup • One workflow is defined as a job • Single script for all steps • Build triggers & parameters like regular projects • Each workflow execu9on is a regular Jenkins build displayed in regular Jenkins views • Graphical visualiza9on of actual build possible Not of visualiza9on job defini9on but of build execu9on

32. Workflow Syntax Card • stage: Enter a new stage ©2014 CloudBees, Inc. All Rights Reserved • node: Allocate node • ws: Allocate workspace • parallel: Execute sub-‐workflow in parallel • retry: Retry the body up to N 9mes • catchError: Catch error and con9nue • input: Input / human interac9on • load: Evaluate a Groovy source file into the workflow script

34. Workflow Syntax Card • archive: Archive ar9facts ©2014 CloudBees, Inc. All Rights Reserved • unarchive: Copy archived ar9fact into the workspace • echo: Print message • dir: Change directory • readFile: Read file from workspace • writeFile: Write file to workspace

38. Possible Future: probably OSS • More plugin interoperability ©2014 CloudBees, Inc. All Rights Reserved • Mul9-‐branch project (& SCM API) integra9on • More advanced SCM • In-‐IDE edi9ng support • Concise syntax

39. Possible Future: probably Jenkins Enterprise • More visualiza9ons ©2014 CloudBees, Inc. All Rights Reserved • Validated merge integra9on • Deployment, incl. blue/green with rollback • Freestyle and/or Build Flow import • Templates integra9on
