Tracker Publisher Plugin

This publisher plugin applies the quality gate to a successfully completed workflow. It then publishes the result as a note in the tracker issue that is specified by the related workflow labels and the tracker instances configuration file.

It exposes no user-facing endpoints.

Environment Variables

Logging

You can set the TRACKERPUBLISHER_DEBUG_LEVEL (all upper-cased) or DEBUG_LEVEL environment variables to DEBUG to add additional information in the console for the launched service. It defaults to INFO. (Please note that setting DEBUG_LEVEL to DEBUG will produce tons of logs.)

The possible values are NOTSET, DEBUG, INFO, WARNING, ERROR, and FATAL. Those values are from the most verbose, NOTSET, which shows all logs, to the least verbose, FATAL, which only shows fatal errors.

If TRACKERPUBLISHER_DEBUG_LEVEL is not defined then the value of DEBUG_LEVEL is used (or INFO if DEBUG_LEVEL is not defined either).

Access logs are only shown at NOTSET and DEBUG levels.

Tracker Instances

The TRACKERPUBLISHER_INSTANCES (all upper-cased) environment variable must be defined to use the plugin. This variable must refer to an existing file that contains tracker instances definitions.

Tip

If the content of this referred file changes, the tracker instances definitions used by the Tracker publisher plugin will change accordingly. You do not need to restart the plugin.

Tracker Instances File

The tracker publisher plugin needs at least one configured tracker instance. You must create a YAML file to configure your instance or instances.

Tracker instances files must use YAML syntax and may have a .yml or .yaml file extension.

A tracker instances file has two mandatory sections: default-instance and instances. 

default-instance: main.instance

instances:
- name: main.instance
  endpoint: http://example.com
  type: gitlab
  keep-history: false
  token: 1e49e4nfgkd9333
  default-qualitygate: nightly.quality.gate
- name: backup.instance
  ...

default-instance is the name of the default tracker instance. This section is mandatory and the instance name must be present in instances.

instances section, which is also mandatory, lists the available tracker instances. It must contain at least one instance that will be used by Tracker publisher plugin to publish the quality gate results.

Each tracker instance is described by the following (possibly optional) items:

  • name: name of a tracker instance. Must be unique. Required.
  • type: type of a tracker instance. Currently supported types: gitlab. Required.
  • keep-history: true or false. When set to false, the most recent results for an applied quality gate on the target are updated, otherwise, all the results are kept. Required.
  • endpoint: URL of a tracker instance. Required.
  • token: tracker authentication token.
  • default-qualitygate: name of the default quality gate to apply when the instance is used.

Configuration File

This plugin has a configuration file (trackerpublisher.yaml by default) that describes the common service configuration options.

If no configuration file is found it will default to the following values:

apiVersion: opentestfactory.org/v1beta2
kind: ServiceConfig
current-context: default
contexts:
- name: default
  context:
    port: 443
    host: 127.0.0.1
    ssl_context: adhoc
    eventbus:
      endpoint: https://127.0.0.1:38368
      token: token
    services:
      qualitygate:
        endpoint: http://127.0.0.1:12312
        token: reuse

The configuration included in the ‘allinone’ image is described in “Common settings.” The listening port is 7797 and the bind address is 127.0.0.1 as the service exposes no user-facing endpoints.

Subscriptions

The Tracker publisher plugin subscribes to the following events:

kind apiVersion
WorkflowCompleted opentestfactory.org/v1alpha1

The Tracker publisher plugin exposes an /inbox endpoint that is used by the event bus to post relevant events.

Launch Command

If you want to manually start the Tracker publisher plugin, use the following command:

python -m opentf.plugins.trackerpublisher.main [--context context] [--config configfile]

Additional command-line options are available and described in “Command-line options.”
