[JJB] Jenkins Job Builder - any users here?

[Adam Romanek]

Hi Jenkins community!

Any Jenkins Job Builder users here? Would be good to know how many of you are reading this, so please leave a comment. There is a dedicated discussion group for JJB but it seems really few people are subscribed. Anyway please leave a comment here if you use JJB.

For those who are not familiar, Jenkins Job Builder is a project written in Python which allows describing jobs in a YAML format. It's really mature, it has a long history and supports pretty advanced use cases but my feeling is few people actually know about it and use it. There are probably many reasons for this. Hopefully we can improve this over time.

Recently I started a thread on dropping support for Python 2 in JJB. It would be nice to hear your opinions, especially if you still rely on Python 2.

Looking forward to your feedback.

Best regards,

Adam Romanek

We do use it and we like it :-)

I have plan to try it in our projects, but it is still a little bit difficult for me to choose between Job DSL and it. I am try to find a tool with which I can create a meta job in Jenkins that allows users to fill there git url and then it will checkout the code and read some .yml file to create / update a job automatically.

What you want are (Multibranch-) Pipeline jobs.

Not exactly. I have already used Jenkins pipeline to define the CI/CD workflow. The problem is I still need to create Jenkins job manually in the web UI to run those pipeline scripts. I hope this could also be automated. In the end users just need to tell the meta job where their repos are, and the meta job will created the pipeline Job automatically by reading some .yml file in the repos they provided.

Ah, OK. Got it now.

I guess then it's best to use Job-DSL. You can create a seed job which reads some Job-DSL code along with a configuration file from a repository (or even separate ones). The DSL code then just iterates over the entries in the configuration file and creates a job for each one, maybe like (in YAML):

---
jobs:

  - name: job_1

    repository:

      credentials: <credentials id>

      url: <ssh or https repo url>

    type: <either pipeline or multibranch pipeline>

  - name: folder/job2

    repository:

      ...

This way users can update the file, issue a merge request, which triggers your seed job after merge...

HTH...

Yes, I think that's how it should be.  But the Job DSL document only shows how to use freestyle job as a seed job. I am wondering is their any example showing how to use a pipeline job as a seed job.  Meanwhile Jenkins Job Builder can do the similar thing via command line. That's why I feel difficult to choose betweeen them.
