I want to have one step, that will setup everything and then in parallel run other steps. Currently I have something like this:

image: python:3.9.16-alpine pipelines: default: - step: runs-on: - self.hosted - regressiontests name: First Step clone: enabled: false caches: - pip script: - apk add git - apk add openssh-client - git clone myrepository.git - pip install -r myrepository/requirements.txt - echo $ENV_FILE | base64 -d -i > myrepository/.env artifacts: - myrepository/** - step: runs-on: - self.hosted - regressiontests name: Second Step clone: enabled: false caches: - pip script: - cd myrepository - pip install -r requirements.txt parallel: - step: name: Step 2.1 script: - python fancy command 1 - step: name: Step 2.2 script: - python fancy command 2 - step: name: Step 2.3 script: - python fancy command 3 - step: name: Step 2.4 script: - python fancy command 4

But the only steps that I see is First Step and Second Step none of parallel steps is executed in pipelines enter image description here

  1. That's not the correct syntax for parallel steps. Checkout https://support.atlassian.com/bitbucket-cloud/docs/set-up-or-run-parallel-steps/
image: python:3.9.16-alpine pipelines: default: - step: name: First Step script: [] - step: name: Second Step script: [] - parallel: - step: name: Step 3.1 script: [] - step: name: Step 3.2 script: [] # ...

This what I think you are trying to achieve

BUT

  1. Each step script happens in a new pristine docker container, so any setup must happen in the same script where the software will be used.

Therefore I am afraid your whole effort to speed up your steps setup is futile.

Instead, you'd like to tune your caches. For python you may want to cache both ~/.cache/pip and a virtualenv so that pip install -r ... instructions are sped up.

Plus, I have a feeling that bitbucket artifacts are quite slow so I'd expect disabling the repository clone in every step to be actually slower. I'd use a shallow clone instead with

clone: depth: 1
