Features
TaskRuns#4990)A
PipelineTaskwith aMatrixis fanned out into parallelTaskRunswhich are executed in parallel.The TaskRunImagePullFailed logic now covers sidecars, and the error message includes the step name and the image
The default maximum count of
TaskRunsorRunsfrom a givenMatrixis 256. Users can configure this value for their installations.✨ TEP-0090: Add Matrix Package (TEP-0090: Add Matrix Package #4934)
✨ [TEP-0076]Support Results Array Indexing ([TEP-0076]Support Results Array Indexing #4911)
Support indexing array results substitution as an alpha feature.
A task can specify a type to produce array result, such as:
results:
- name: array-results
type: array
description: The array results
And the task script can populate result in an array form with:
echo -n "["hello","world"]" | tee $(results.array-results.path)
and we can refer to the array results elements via index in param like:
params:
- name: foo
value: "$(tasks.task1.results.array-results[1])"
This feature is part of the TEP-0076.
✨ [TEP-0075] Validate task result variable of object type ([TEP-0075] Validate task result variable of object type #4878)
✨ [TEP-0075] Validate against using the whole object in task steps ([TEP-0075] Validate against using the whole object in task steps #4861)
