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:
- 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...
