He does so by traveling to various conferences all across the globe. He graduated from college with a degree in computer programming in the last millennium. Apart from a little break to get his BSc in computational astrophysics, he has always worked in the industry. In his daily job, Joel is a developer advocate with MongoDB, where he connects with software engineers to help them make the web better by using best practices around JavaScript. In his free time, he can be found stargazing on a campground somewhere or brewing a fresh batch of beer in his garage.

Using when expressions with results

A common use case when dealing with pipelines is to block the execution of certain tasks based on the outcome of an earlier task. In order to achieve that, you would need to use a result. This is what you will do in this section.

First, you will create a new task that will generate a random number. Then, you will use a pipeline similar to the one you've used so far in this chapter. The decision to run the win or lose task will depend on the resulting random number from the first task:

  1. In a new file called guess-result.yaml, create the following task that uses a Universal Base Image (UBI) to generate a random number and store it as a result:
    apiVersion: tekton.dev/v1beta1
    kind: Task
    metadata:
      name: random-number-generator
    spec:
      results:
        - name: random-number
          description: random number
      steps:
        - name: generate-number...
