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.

A connection ArbitraryName that uses the gerrit driver must be supplied to the trigger.

SMTP

A simple email reporter is also available.

A connection ArbitraryName that uses the smtp driver must be supplied to the reporter.

SMTP Configuration

zuul.conf contains the SMTP server and default to/from as described in zuul.conf.

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
    source: my_gerrit
    trigger:
      my_gerrit:
        - event: change-merged
    success:
      outgoing_smtp:
        to: you@example.com
    failure:
      internal_smtp:
        to: you@example.com
        from: alternative@example.com
        subject: Change {change} failed

SQL

This reporter is used to store results in a database.

A connection ArbitraryName that uses the sql driver must be supplied to the reporter.

SQL Configuration

zuul.conf contains the database connection and credentials. To store different reports in different databases you’ll need to create a new connection per database.

The sql reporter is used to store the results from individual builds rather than the change. As such the sql reporter does nothing on “start” or “merge-failure”.

score
A score to store for the result of the build. eg: -1 might indicate a failed build similar to the vote posted back via the gerrit reporter.

For example

pipelines:
  - name: post-merge
    manager: IndependentPipelineManager
    source: my_gerrit
    trigger:
      my_gerrit:
        - event: change-merged
    success:
      mydb_conn:
          score: 1
    failure:
      mydb_conn:
          score: -1
