Artifacts are not pulled in a child pipeline

Question

This is my gitlab ci config. In the build stage the application is build in the distfolder, which is stored as an artifact. The next deploy stage is a trigger to run a child pipeline for the deployment.

But the dist artifacts aren't pulled for the child pipeline, so the child job fails.

1. How do I get the dist artifacts in the child job?
2. Even if the child deploy job fails, the parent pipeline shows a complete pass. I would expect to see, that at least one child has failed.

.gitlab-ci.yml

stages:
  - build
  - deployment

build:
  stage: build
  cache:
    key: ${CI_COMMIT_REF_SLUG}
    policy: pull
    paths:
      - node_modules/
  artifacts:
    when: always
    paths:
      - deployment.yml
      - dist/
  script:
    - node ./build-app.js # creates dist folder
    - node ./generate-pipeline.js # generates deployment.yml

trigger-deploy:
  stage: deployment
  trigger:
    include:
      - artifact: deployment.yml
        job: build

deployment.yml

stages:
  - deploy

app1-deploy:
  stage: deploy
  script:
    - ls dist # fails, as dist folder is not existing

Answer 1

The 'trigger-deploy' job needs a dependency of the 'build' job, to allow the artifacts to be providable.

To get the parent to fail when the child pipeline fails you'll need to add a strategy to the include strategy: depend. see last example

Answer 2

needs:pipeline:job

A child pipeline can download artifacts from a job in its parent pipeline or another child pipeline in the same parent-child pipeline hierarchy.
