Nested steps inside a parallel step?

[Anton Usov]

It is possible to have nested steps inside a parallel step?

I want to have something like that:

pipelines:
  default:
    - step:
        script:
          - ./integration-tests.sh --batch 1
    - parallel:
        - step:
            script:
              - ./integration-tests.sh --batch 2
        - step:
            - step:
                script:
                  - ./deploy.sh
            - step:
                script:
                  - ./integration-tests.sh --batch 3

Hello @Anton Usov,

Nested steps (a step inside of a step) are not allowed anywhere in the file, not just inside of parallel.

Basically, all steps can have just two levels: top-level sequentially executed steps and steps inside of parallel section, which are executed concurrently.

My guess is that your goal is to execute multiple steps sequentially within a parallel section. If so, unfortunately it is not possible in Pipelines at the moment. The only way to keep parallelism would be to prepare a Docker image that every nested step could run with, and then squash sequential steps into one.

Hope this helps. Let me know if you have any questions.

Cheers,
Daniil

Thank you!
I actually expected an answer like that.

@Anton Usov @ and what about 2 parallel sections that are run sequentially
its not nested but actually can postpone some parallel runs..
Something like this:

pipelines:
  default:
    - parallel:
        - step:
            script:
              - ./parallel1-before.sh
        - step:
            script:
              - ./parallel2-before.sh
    - parallel:
        - step:
            script:
              - ./parallel1-after.sh
        - step:
            script:
              - ./parallel2-after.sh

That's what I ended up doing.
