Pipeline schedules

Notes:

Introduced in GitLab 9.1 as Trigger Schedule.

Renamed to Pipeline Schedule in GitLab 9.2.

Cron notation is parsed by Fugit.

Pipelines are normally run based on certain conditions being met. For example, when a branch is pushed to repository.

Pipeline schedules can be used to also run pipelines at specific intervals. For example:

Every month on the 22nd for a certain branch.
Once every day.

In addition to using the GitLab UI, pipeline schedules can be maintained using the Pipeline schedules API.

Configuring pipeline schedules

To schedule a pipeline for project:

Navigate to the project's CI / CD > Schedules page.
Click the New schedule button.
Fill in the Schedule a new pipeline form.
Click the Save pipeline schedule button.

NOTE: Note: Pipelines execution timing is dependent on Sidekiq's own schedule.

In the Schedules index page you can see a list of the pipelines that are scheduled to run. The next run is automatically calculated by the server GitLab is installed on.

Using variables

Introduced in GitLab 9.4.

You can pass any number of arbitrary variables and they will be available in GitLab CI so that they can be used in your .gitlab-ci.yml file.

Using only and except

To configure that a job can be executed only when the pipeline has been scheduled (or the opposite), you can use only and except configuration keywords.

For example:

job:on-schedule:
  only:
    - schedules
  script:
    - make world

job:
  except:
    - schedules
  script:
    - make build

Advanced configuration

The pipelines won't be executed exactly on schedule because schedules are handled by Sidekiq, which runs according to its interval.

For example, only two pipelines will be created per day if:

You set a schedule to create a pipeline every minute (* * * * *).
The Sidekiq worker runs on 00:00 and 12:00 every day (0 */12 * * *).

To change the Sidekiq worker's frequency:

Edit the pipeline_schedule_worker_cron value in your instance's gitlab.rb file.
Restart GitLab.

For GitLab.com, refer to the dedicated settings page.

Working with scheduled pipelines

Once configured, GitLab supports many functions for working with scheduled pipelines.

Running manually

Introduced in GitLab 10.4.

To trigger a pipeline schedule manually, click the "Play" button:

This will schedule a background job to run the pipeline schedule. A flash message will provide a link to the CI/CD Pipeline index page.

NOTE: Note: To help avoid abuse, users are rate limited to triggering a pipeline once per minute.

Taking ownership

Pipelines are executed as a user, who owns a schedule. This influences what projects and other resources the pipeline has access to.

If a user does not own a pipeline, you can take ownership by clicking the Take ownership button. The next time a pipeline is scheduled, your credentials will be used.

NOTE: Note: If the owner of a pipeline schedule doesn't have the ability to create pipelines on the target branch, the schedule will stop creating new pipelines. This can happen if, for example, the owner is blocked or removed from the project, or the target branch or tag is protected. In this case, someone with sufficient privileges must take ownership of the schedule.
