Jester

Build Status

A command line tool to enable more seamless "local" development of Jenkinsfile groovy pipelines without having to do the typical "commit, push, webhook, pipeline job run" to iterate on a pipeline.

Instead, you can use jester, which performs the following:

  • Creates (or uses existing) pipeline job on Jenkins master
  • Updates the pipeline job's value of the pipeline script with a custom string or local Jenkinsfile
  • Runs the pipeline job with the newly modified script
  • Fetches the job console output and saves it to a local file for review

All of this is done from the command line - logging in to the Jenkins UI not required.

Installation

Add this line to your application's Gemfile:

gem 'jester'

And then execute:

$ bundle

Or install it yourself as:

$ gem install jester

Usage

If you don't have a Jenkins instance running, you can run one easily in Docker:

docker run -d -p 8080:8080 --name localjenkins jenkins/jenkins:lts
docker logs localjenkins
open http://localhost:8080
# perform basic setup wizard steps to bring the new Jenkins master online

Then you should be able to run jester using the defaults for -s / --url.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
