Changes

Introducing matrix.strategy to allow pipeline authors to specify explicit combinations dynamically.

apiVersion: tekton.dev/v1
kind: Pipeline
spec:
  tasks:
    - name: clone
      taskRef:
        name: clone
    - name: build
       matrix:
         strategy: $(tasks.setup.results.matrix) # <JSON payload of a list of params and values>

where $(tasks.setup.results.matrix) could be set to:

{"include":  [{"IMAGE": "image", "DOCKERFILE": "path/to/Dockerfile"}]}

or

{"include":  [{"IMAGE": "image-1", "DOCKERFILE": "path/to/Dockerfile1"},
                    {"IMAGE": "image-2", "DOCKERFILE": "path/to/Dockerfile2"},
                    {"IMAGE": "image-3", "DOCKERFILE": "path/to/Dockerfile3"}]}
