We have a cgit server now, which means we should replace all references to github with references to git.openstack.org. Change-Id: I68ad1ce514fb4326c7d9940b5a84999af5b58562

Overview
|
|
========
|
|
|
|
The OpenStack project uses a number of pipelines in Zuul:
|
|
|
|
**check**
|
|
Newly uploaded patchsets enter this pipeline to receive an initial
|
|
+/-1 Verified vote from Jenkins.
|
|
|
|
**gate**
|
|
Changes that have been approved by core developers are enqueued in
|
|
order in this pipeline, and if they pass tests in Jenkins, will be
|
|
merged.
|
|
|
|
**post**
|
|
This pipeline runs jobs that operate after each change is merged.
|
|
|
|
**pre-release**
|
|
This pipeline runs jobs on projects in response to pre-release tags.
|
|
|
|
**release**
|
|
When a commit is tagged as a release, this pipeline runs jobs that
|
|
publish archives and documentation.
|
|
|
|
**silent**
|
|
This pipeline is used for silently testing new jobs.
|
|
|
|
Zuul watches events in Gerrit (using the Gerrit "stream-events"
|
|
command) and matches those events to the pipelines above. If a match
|
|
is found, it adds the change to the pipeline and starts running
|
|
related jobs.
|
|
|
|
The **gate** pipeline uses speculative execution to improve
|
|
throughput. Changes are tested in parallel under the assumption that
|
|
changes ahead in the queue will merge. If they do not, Zuul will
|
|
abort and restart tests without the affected changes. This means that
|
|
many changes may be tested in parallel while continuing to assure that
|
|
each commit is correctly tested.
|
|
|
|
Zuul's current status may be viewed at
|
|
`<http://status.openstack.org/zuul/>`_.
|
|
|
|
Zuul's configuration is stored in
|
|
:file:`modules/openstack_project/files/zuul/layout.yaml`. Anyone may
|
|
propose a change to the configuration by editing that file and
|
|
submitting the change to Gerrit for review.
|
|
|
|
For the full syntax of Zuul's configuration file format, see the `Zuul
|
|
reference manual`_.
