Spinnaker is a simple yet elegant application that allows the user to customize a wide range of inputs to result in many different outcomes, depending on what you desire. One thing it is somewhat lacking is a simple way to allow for user input directly from an email or phone, which is where xMatters comes in. In any Spinnaker pipeline, it is very simple to insert a webhook that fires off a notification to xMatters, then continue the pipeline selecting a stage based on user input, and this guide will show you how to set this up, using an example that “Deploy”s to Dev or Test. We will not actually be deploying anything, but it is just one example of what you could do using Spinnaker’s stages that run a Jenkins job.
