# Pipelines can be triggered manually in the web.
#
# Please do not add new jobs without "rules:" and "*-env". There are &test-refs for everything,
# "docker-env" is used for Rust jobs.
# And "kubernetes-env" for everything else. Please mention "image:" container name to be used
# with it, as there's no default one.

# All jobs are sorted according to their duration using DAG mechanism
# Currently, test-linux-stable job is the longest one and other jobs are
# sorted in order to complete during this job and occupy less runners in one
# moment of time.
