# This job is monitored on github and acts as a required check.
# A few details on the setup:
# We can't monitor a trigger job from github, it has to have a script section.
# We need the monitored job to fail if the downstream pipeline failed, and succeed if
# the downstream pipeline succeeded. If the job is skipped, it isn't taken into account
# on github.
# This is where the on_success job kicks in. It run only if the previous job completes
# and writes `success` in a file that's fetched by the `check-downstream-pipeline` job.
# This allows us to have the check-downstream-pipeline to always run while replicating
# the status of the downstream pipeline.
