Jenkins formula
===============

Jenkins CI is an open source automation server written in Java. Jenkins 
helps to automate the non-human part of software development process, with 
continuous integration and facilitating technical aspects of continuous delivery.

(*Source*: `Wikipedia <https://en.wikipedia.org/wiki/Jenkins_(software)>`_ )

More information can be found at `<https://jenkins.io/>`_

Setup jenkins client, works with Salt 2016.3+, supports pipeline workflow
projects only now.

Dependencies
==============

To install on Ubuntu, you will need to add the jenkins debian repository to the target
server. You can do this with the `salt-formula-linux formula <https://github.com/salt-formulas/salt-formula-linux>`_ ,
with the following pillar data:

.. code-block:: yaml

  linux:
    system:
      enabled: true
        repo:
        jenkins:
          enabled: true
          source: "deb http://pkg.jenkins.io/debian-stable binary/"
          key_url: "https://pkg.jenkins.io/debian/jenkins-ci.org.key"

This state will need to be applied *before* the jenkins state.

Using this formula
==================

To use this formula, you must install the formula to your salt master as documented
in `saltstack formula docs <https://docs.saltstack.com/en/latest/topics/development/conventions/formulas.html#installation>`_

This formula is driven by pillar data, and can be used to install either a Jenkins Master
or Client. See pillar data below for examples.


Sample pillars

Setting job max builds to keep (amount of last builds stored on Jenkins master)

.. code-block:: yaml

    jenkins:
      client:
        job:
          my-amazing-job:
            type: workflow
            discard:
              build:
                keep_num: 5
                keep_days: 5
              artifact:
                keep_num: 6
                keep_days: 6


Using job templates in similar way as in jjb. For now just 1 defined param is
supported.

.. code-block:: yaml

    jenkins:
      client:
        job_template:
          test_workflow_template:
            name: test-{{formula}}-workflow
            template:
              type: workflow
              display_name: Test jenkins {{name}} workflow
              param:
                repo_param:
                  type: string
                  default: repo/{{formula}}
              script:
                repository: base
                file: workflows/test_formula_workflow.groovy
            param:
              formula:
              - aodh
              - linux
              - openssh

Interpolating parameters for job templates.

.. code-block:: yaml

    _param:
      salt_formulas:
      - aodh
      - git
      - nova
      - xorg
    jenkins:
      client:
        job_template:
          test_workflow_template:
            name: test-{{formula}}-workflow
            template:
              ...
            param:
              formula: ${_param:salt_formulas}

Or simply define multiple jobs and it's parameters to replace from template:

.. code-block:: yaml

   jenkins:
     client:
       job_template:
         test_workflow_template:
           name: test-{{name}}-{{myparam}}
           template:
             ...
           jobs:
             - name: firstjob
               myparam: dummy
             - name: secondjob
               myparam: dummyaswell

.. code-block:: yaml

    jenkins:
      client:

            type: workflow

                max_concurrent_total: 1
                throttle_option: category #one of project (default or category)
                categories:
                  - my_throuttle_category
        plugin:
          swarm:

          hipchat:
            enabled: false
            restart: true
