zuul.d/jobs.yaml

# Shared zuul config common to all tenants.
# Contains definitions of trusted jobs.

# Changes to the base require a special procedure, because they can
# not be tested before landing, and if they are faulty, they will
# break all jobs, meaning subsequent corrections will not be able to
# land.  To make a change:
#
# 1) Ensure that base-test and its playbooks are identical to base.
# 2) Make the change to base-test and/or its playbooks.
# 3) Merge the change from step 2.  No jobs normally use base-test, so
#    this is safe.
# 4) Propose a change to a job to reparent it to base-test.  Choose a
#    job which will exercise whatever you are changing.  The
#    "unittests" job in zuul-jobs is a good choice.  Use [DNM] in the
#    commit subject so that people know not to merge the change.  Set
#    it to "Work in progress" so people don't review it.
# 5) Once test results arrive for the change in step 2, make a change
#    which copies the job and/or playbooks of base-test to base.  In
#    the commit message, link to (without using Depends-On:) the
#    change from step 4 so reviewers can see the test results.
# 6) Once the change in step 5 merges, abandon the change from step 4.

      The base job for Gerrit's installation of Zuul.

      All jobs ultimately inherit from this.  It runs a pre-playbook
      which copies all of the job's prepared git repos on to all of
      the nodes in the nodeset.  It runs a post-playbook which copies
      all of the files in the logs/ subdirectory of the executor
      work directory to the logserver.

      It also sets default timeout and nodeset values (which may be
      overidden).

      Responds to these variables:

      .. zuul:jobvar:: base_serial
         :default: Omitted

         This sets the serial keyword in the pre and post playbooks
         which can be an integer or percentage.
