GitLab
The GitLab driver supports sources, triggers, and reporters. It can interact with the public GitLab.com service as well as site-local installations of GitLab.
Configure GitLab
Zuul needs to interact with projects by:
receiving events via web-hooks
performing actions via the API
web-hooks
Projects to be integrated with Zuul needs to send events using webhooks. This can be enabled at Group level or Project level in “Settings/Webhooks”
“URL” set to
http://<zuul-web>/api/connection/<conn-name>/payload
“Merge request events” set to “on”
“Push events” set to “on”
“Tag push events” set to “on”
“Comments” set to “on”
Define a “Secret Token”
API
In order to manage multiple projects using a single connection, Zuul needs a global access to projects, which can only be achieved by creating a specific Zuul user. This user counts as a licensed seat.
The API token must be created in user Settings, Access tokens. The Zuul user’s API token configured in zuul.conf must have the following ACL rights: “api”.
Connection Configuration
The supported options in zuul.conf
connections are:
-
<gitlab connection>
-
<gitlab connection>.driver (required)
- gitlab
The connection must set
driver=gitlab
for GitLab connections.
-
<gitlab connection>.api_token_name
The user’s personal access token name (Used if cloneurl is http(s)) Set this parameter if authentication to clone projects is required
-
<gitlab connection>.api_token
The user’s personal access token
-
<gitlab connection>.webhook_token
The webhook secret token.
-
<gitlab connection>.server
Default:gitlab.com
Hostname of the GitLab server.
-
<gitlab connection>.canonical_hostname
The canonical hostname associated with the git repos on the GitLab server. Defaults to the value of <gitlab 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 GitLab 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.
-
<gitlab connection>.baseurl
Default:https://{server}
Path to the GitLab web and API interface.
-
<gitlab connection>.sshkey
Path to SSH key to use (Used if cloneurl is ssh)
-
<gitlab connection>.cloneurl
Default:{baseurl}
Omit to clone using http(s) or set to
ssh://git@{server}
. If api_token_name is set and cloneurl is either omitted or is set without credentials, cloneurl will be modified to use credentials as this:http(s)://<api_token_name>:<api_token>@<server>
. If cloneurl is defined with credentials, it will be used as is, without modification from the driver.
-
<gitlab connection>.driver (required)
Trigger Configuration
GitLab webhook events can be configured as triggers.
A connection name with the GitLab driver can take multiple events with the following options.
-
pipeline.trigger.<gitlab source>
The dictionary passed to the GitLab pipeline
trigger
attribute supports the following attributes:-
pipeline.trigger.<gitlab source>.event (required)
The event from GitLab. Supported events are:
- gl_merge_request
- gl_push
-
pipeline.trigger.<gitlab source>.action
A gl_merge_request event will have associated action(s) to trigger from. The supported actions are:
- opened
Merge request opened.
- changed
Merge request synchronized.
- merged
Merge request merged.
- comment
Comment added to merge request.
- approved
Merge request approved.
- unapproved
Merge request unapproved.
- labeled
Merge request labeled.
-
pipeline.trigger.<gitlab source>.comment
This is only used for
gl_merge_request
andcomment
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 merge request.
-
pipeline.trigger.<gitlab source>.labels
This is only used for
gl_merge_request
andlabeled
actions. It accepts a string or a list of strings that are searched into the list of labels set to the merge request.
-
pipeline.trigger.<gitlab source>.ref
This is only used for
gl_push
events. This field is treated as a regular expression and multiple refs may be listed. GitLab always sends full ref name, eg.refs/heads/bar
and this string is matched against the regular expression.
-
pipeline.trigger.<gitlab source>.event (required)
Reporter Configuration
Zuul reports back to GitLab via the API. Available reports include a Merge Request comment containing the build results. Status name, description, and context is taken from the pipeline.
-
pipeline.<reporter>.<gitlab source>
To report to GitLab, the dictionaries passed to any of the pipeline reporter attributes support the following attributes:
-
pipeline.<reporter>.<gitlab source>.comment
Default:true
Boolean value that determines if the reporter should add a comment to the pipeline status to the GitLab Merge Request.
-
pipeline.<reporter>.<gitlab source>.approval
Bolean value that determines whether to report approve or unapprove into the merge request approval system. To set an approval the Zuul user must be a Developer or Maintainer project’s member. If not set approval won’t be reported.
-
pipeline.<reporter>.<gitlab source>.merge
Default:false
Boolean value that determines if the reporter should merge the Merge Request. To merge a Merge Request the Zuul user must be a Developer or Maintainer project’s member. In case of developer, the Allowed to merge setting in protected branches must be set to Developers + Maintainers.
-
pipeline.<reporter>.<gitlab source>.comment
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.
pipeline:
require:
gitlab:
open: true
This indicates that changes originating from the GitLab connection must be in the opened state (not merged yet).
-
pipeline.require.<gitlab source>
The dictionary passed to the GitLab pipeline require attribute supports the following attributes:
-
pipeline.require.<gitlab source>.open
A boolean value (
true
orfalse
) that indicates whether the Merge Request must be open in order to be enqueued.
-
pipeline.require.<gitlab source>.merged
A boolean value (
true
orfalse
) that indicates whether the Merge Request must be merged or not in order to be enqueued.
-
pipeline.require.<gitlab source>.approved
A boolean value (
true
orfalse
) that indicates whether the Merge Request must be approved or not in order to be enqueued.
-
pipeline.require.<gitlab source>.labels
if present, the list of labels a Merge Request must have.
-
pipeline.require.<gitlab source>.open
