Generate Jenkins Job Configuration Automatically?
Job DSL Plugin
The job-dsl-plugin allows the programmatic creation of projects using a DSL. Pushing job creation into a script allows you to automate and standardize your Jenkins installation, unlike anything possible before.
More –
Multi-Branch Project Plugin
This plugin adds additional project types that create sub-projects for each branch using a shared configuration.
Job Generator Plugin
This plugin adds a new job type “Job Generator” which can generate new projects when executed.
Jenkins Job Builder
Jenkins Job Builder takes simple descriptions of Jenkins jobs in YAML or JSON format and uses them to configure Jenkins. You can keep your job descriptions in human readable text format in a version control system to make changes and auditing easier. It also has a flexible template system, so creating many similarly configured jobs is easy.

Generating New Jenkins Jobs From Templates and Parameterised Builds
We use Jenkins to run our builds in a continuously. This is great, but you still have to do a fair bit of configuration each time you set up a new job. If you have a fairly static set of builds this isn’t a problem. We found ourselves in a situation where we had to create a lot of very similar builds quite regularly. Creating a new job by hand and manually changing the 10 or so tiny little things in each build is a pain and error prone. So…automate that too!

Chef – Documenting Cookbooks automatically


Problems Area –

Our infrastructure has many cookbooks that aim to be reusable, primarily through encapsulating behaviour in LWRPs. This led to an explosion of LWRPs and sometimes the documentation didn’t keep up or did just not exist.

Solution 1: Follow Best Practices 

This command will create a README.rdoc by default, and I prefer Markdown, so I specify the -r md option.

> knife cookbook create smartmontools -r md

Solution 2: Automate using plugins which should be generated automatcially must contain information about the recipes, attributes, platform compatibility and cookbook requirements (i.e. depends, recommends, suggests etc).

Mathias Lafeldt wrote a knife plugin that generates an initial from the metadata.rb file in a a cookbook.

Extension of Mathias Lafeldt was done here with regenerate from the cookbook source code
