Reporters
=========
Zuul can communicate results and progress back to configurable
protocols. For example, after succeeding in a build a pipeline can be
configured to post a positive review back to Gerrit.
There are three stages when a report can be handled. That is on:
Start, Success or Failure. Each stage can have multiple reports.
For example, you can set verified on Gerrit and send an email.
Gerrit
------
Zuul works with standard versions of Gerrit by invoking the
``gerrit`` command over an SSH connection. It reports back to
Gerrit using SSH.
The dictionary passed to the Gerrit reporter is used for ``gerrit
review`` arguments, with the boolean value of ``true`` simply
indicating that the argument should be present without following it
with a value. For example, ``verified: 1`` becomes ``gerrit review
--verified 1`` and ``submit: true`` becomes ``gerrit review
--submit``.
Gerrit Configuration
~~~~~~~~~~~~~~~~~~~~
The configuration for posting back to Gerrit is shared with the Gerrit
trigger in zuul.conf as described in :ref:`zuulconf`.
SMTP
----
A simple email reporter is also available.
SMTP Configuration
~~~~~~~~~~~~~~~~~~
zuul.conf contains the SMTP server and default to/from as describe
in :ref:`zuulconf`.
Each pipeline can overwrite the subject or the to or from address by
providing alternatives as arguments to the reporter. For example, ::
pipelines:
- name: post-merge
manager: IndependentPipelineManager
trigger:
- event: change-merged
success:
smtp:
to: you@example.com
failure:
smtp:
to: you@example.com
from: alternative@example.com
subject: Change {change} failed
