Defining jobs pipelines

Sometimes you want to chain multiple jobs together. For example you might have a deploy job that must only be run after integration and unit tests succeeded.

In jenkins, you assemble pipelines by editing the jobs configurations, hooking jobs to each other one by one. This process is cumbersome, and it can be hard to visualize the whole pipeline.

Jenskipper solves this by separating the pipelines definitions from the jobs. Pipelines are defined in the pipelines.txt file. Here is an example chaining 3 jobs together:

unit-tests > integration-tests > deployment

By default the jobs chain is interrupted if one of the jobs fail. If you need to continue running jobs in the pipeline after a failure or an unstable result, use the ~> and ?> operators respectively:

unit-tests > integration-tests ~> deployment

Here the deployment job will be executed even if the integration-tests fails, but nothing will run if unit-tests fails.

A job may also trigger more than one job:

A > B > D
A > C

Or a job can be triggered by multiple jobs:

A > C
B > C

In this last example, C will be triggered if A or B finishes successfully.
