# Use one single job to generate multiple yaml files for the downstream pipelines.
# FIXME: This is only necessary due to a GitLab limitation:
# https://gitlab.com/gitlab-org/gitlab/-/issues/347469
# We work around this by generating manifest-integration-jobs.yml from a Jinja2 template
# and insert the trigger project via a Jinja2 variable.
# The issue is already fixed and will be released in GitLab 15.3:
# https://gitlab.com/gitlab-org/gitlab/-/merge_requests/92346
# As soon as we update to this version, we can get rid of the generate job and convert
# the Jinja2 template to a simple YAML file.

    # The job generation script implicitly passes the OS environment to the template, so
    # that the template has access to all GitLab CI variables. Hence there is no need
    # to explicitly pass any of them as command line arguments.
