How can I define reusable scripts and run them in parallel for a branch

Eric Poe

Given the following pipeline configuration, the Pipeline Validator claims it is good but the pipeline gives an error: `[pipelines > branches > FOO-10751-snapshot-used-as-clean-source > 0 > parallel > steps > 0]. The step section is empty or null.`

• Am I wrong? How can I fix this?
• Is the pipeline runner wrong?
• Is the Pipeline Validator wrong?

 

definitions:
  steps: # Note: the "&" is a yaml anchor that allows reusing this particular step
    - step: 
        name: &PHP-Code-Quality
        image: foo/php-ci:1
        script:
          - |
            php bunch-of-stuff.php
    - step:
        name: &JS-Code-Lint
        image: node:18
        script:
          - |
            npx bunch-of-stuff
    - step:
        name: &Update-Snapshot
        runs-on:
          - server.test
          - self.hosted
          - linux.shell
        script:
          - bunch-of-stuff.sh
pipelines:
  default:
    - parallel:
        steps:
          - step: *PHP-Code-Quality
          - step: *JS-Code-Lint
          - step: *Update-Snapshot
  branches:
    FOO-10751-snapshot-used-as-clean-source:
      - parallel:
          steps:
            - step: *PHP-Code-Quality
            - step: *JS-Code-Lint
            - step: *Update-Snapshot

 

Eventually, I will want to use a specific branch for staging a release via Pipelines. This is a preliminary step towards that goal.

Hi Eric and welcome to the community!

There is a bug with the validator and it doesn't show any errors when yaml anchors are used.

I think the culprit for the error you see is that you are using the anchors in the step name, instead of after - step:

Can you try adjusting the definitions as follows, and let me know if it works?

definitions:
  steps: # Note: the "&" is a yaml anchor that allows reusing this particular step
    - step: &PHP-Code-Quality
        name: PHP-Code-Quality
        image: foo/php-ci:1
        script:
          - |
            php bunch-of-stuff.php
    - step: &JS-Code-Lint
        name: JS-Code-Lint
        image: node:18
        script:
          - |
            npx bunch-of-stuff
    - step: &Update-Snapshot
        name: Update-Snapshot
        runs-on:
          - server.test
          - self.hosted
          - linux.shell
        script:
          - bunch-of-stuff.sh

Kind regards,
