Pagure

The Pagure driver supports sources, triggers, and reporters. It can interact with the public Pagure.io service as well as site-local installations of Pagure.

Configure Pagure

The user’s API token configured in zuul.conf must have the following ACL rights:

“Merge a pull-request” set to on (optional, only for gating)
“Flag a pull-request” set to on
“Comment on a pull-request” set to on
“Modify an existing project” set to on

Each project to be integrated with Zuul needs:

“Web hook target” set to http://<zuul-web>/zuul/api/connection/<conn-name>/payload
“Pull requests” set to on
“Open metadata access to all” set to off (optional, expected if approval based on PR a metadata tag)
“Minimum score to merge pull-request” set to the same value than the score requierement (optional, expected if score requierement is defined in a pipeline)

Furthermore, the user must be added as project collaborator (ticket access level), to be able to read the project’s webhook token. This token is used to validate webhook’s payload. But if Zuul is configured to merge pull requests then the access level must be commit.

Connection Configuration

The supported options in zuul.conf connections are:

<pagure connection>

<pagure connection>.driver (required)

pagure: The connection must set driver=pagure for Pagure connections.

<pagure connection>.api_token: The user’s API token with the Modify an existing project capability.

<pagure connection>.server Default: pagure.io: Hostname of the Pagure server.

<pagure connection>.canonical_hostname: The canonical hostname associated with the git repos on the Pagure server. Defaults to the value of <pagure connection>.server. This is used to identify projects from this connection by name and in preparing repos on the filesystem for use by jobs. Note that Zuul will still only communicate with the Pagure server identified by server; this option is useful if users customarily use a different hostname to clone or pull git repos so that when Zuul places them in the job’s working directory, they appear under this directory name.

<pagure connection>.baseurl Default: https://{server}: Path to the Pagure web and API interface.

<pagure connection>.cloneurl Default: https://{baseurl}: Path to the Pagure Git repositories. Used to clone.

<pagure connection>.app_name Default: Zuul: Display name that will appear as the application name in front of each CI status flag.

<pagure connection>.source_whitelist Default: '': A comma separated list of source ip adresses from which webhook calls are whitelisted. If the source is not whitelisted, then call payload’s signature is verified using the project webhook token. An admin access to the project is required by Zuul to read the token. White listing a source of hook calls allows Zuul to react to events without any authorizations. This setting should not be used in production.

Trigger Configuration

Pagure webhook events can be configured as triggers.

A connection name with the Pagure driver can take multiple events with the following options.

pipeline.trigger.<pagure source>

The dictionary passed to the Pagure pipeline trigger attribute supports the following attributes:

pipeline.trigger.<pagure source>.event (required)

The event from Pagure. Supported events are:

pg_pull_request

pg_pull_request_review

pg_push

pipeline.trigger.<pagure source>.action

A pg_pull_request event will have associated action(s) to trigger from. The supported actions are:

opened: Pull request opened.

changed: Pull request synchronized.

closed: Pull request closed.

comment: Comment added to pull request.

status: Status set on pull request.

tagged: Tag metadata set on pull request.

A pg_pull_request_review event will have associated action(s) to trigger from. The supported actions are:

thumbsup: Positive pull request review added.

thumbsdown: Negative pull request review added.

pipeline.trigger.<pagure source>.comment: This is only used for pg_pull_request and comment actions. It accepts a list of regexes that are searched for in the comment string. If any of these regexes matches a portion of the comment string the trigger is matched. comment: retrigger will match when comments containing ‘retrigger’ somewhere in the comment text are added to a pull request.

pipeline.trigger.<pagure source>.status: This is used for pg_pull_request and status actions. It accepts a list of strings each of which matches the user setting the status, the status context, and the status itself in the format of status. For example, success or failure.

pipeline.trigger.<pagure source>.tag: This is used for pg_pull_request and tagged actions. It accepts a list of strings and if one of them is part of the event tags metadata then the trigger is matched.

pipeline.trigger.<pagure source>.ref: This is only used for pg_push events. This field is treated as a regular expression and multiple refs may be listed. Pagure always sends full ref name, eg. refs/tags/bar and this string is matched against the regular expression.

Reporter Configuration

Zuul reports back to Pagure via Pagure API. Available reports include a PR comment containing the build results, a commit status on start, success and failure, and a merge of the PR itself. Status name, description, and context is taken from the pipeline.

pipeline.<reporter>.<pagure source>

To report to Pagure, the dictionaries passed to any of the pipeline reporter attributes support the following attributes:

pipeline.<reporter>.<pagure source>.status: String value (pending, success, failure) that the reporter should set as the commit status on Pagure.

pipeline.<reporter>.<pagure source>.comment Default: true: Boolean value that determines if the reporter should add a comment to the pipeline status to the Pagure Pull Request. Only used for Pull Request based items.

pipeline.<reporter>.<pagure source>.merge Default: false: Boolean value that determines if the reporter should merge the pull Request. Only used for Pull Request based items.

Requirements Configuration

As described in pipeline.require pipelines may specify that items meet certain conditions in order to be enqueued into the pipeline. These conditions vary according to the source of the project in question. To supply requirements for changes from a Pagure source named pagure, create a configuration such as the following:

pipeline:
  require:
    pagure:
      score: 1
      merged: false
      status: success
      tags:
        - gateit

This indicates that changes originating from the Pagure connection must have a score of 1, a CI status success and not being already merged.

pipeline.require.<pagure source>

The dictionary passed to the Pagure pipeline require attribute supports the following attributes:

pipeline.require.<pagure source>.score: If present, the minimal score a Pull Request must reached.

pipeline.require.<pagure source>.status: If present, the CI status a Pull Request must have.

pipeline.require.<pagure source>.merged: A boolean value (true or false) that indicates whether the Pull Request must be merged or not in order to be enqueued.

pipeline.require.<pagure source>.open: A boolean value (true or false) that indicates whether the Pull Request must be open or closed in order to be enqueued.

pipeline.require.<pagure source>.tags: if present, the list of tags a Pull Request must have.

Reference pipelines configuration

Here is an example of standard pipelines you may want to define:
