Pipeline schedules can be used to run a pipeline at specific intervals, for example every month on the 22nd for a certain branch.
Using Pipeline schedules
In order to schedule a pipeline:
- Navigate to your project's Pipelines ➔ Schedules and click the New Schedule button.
- Fill in the form
- Hit Save pipeline schedule for the changes to take effect.
Attention: The pipelines won't be executed precisely, because schedules are handled by Sidekiq, which runs according to its interval. See advanced admin configuration for more information.
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.
Running a scheduled pipeline 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.
To help avoid abuse, users are rate limited to triggering a pipeline once per minute.
Making use of scheduled pipeline 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
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.
- make world
- make build
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: When the owner of the schedule doesn't have the ability to create pipelines anymore, due to e.g., being blocked or removed from the project, or lacking the permission to run on protected branches or tags. When this happened, the schedule is deactivated. Another user can take ownership and activate it, so the schedule can be run again.
Advanced admin configuration
The pipelines won't be executed precisely, because schedules are handled by
Sidekiq, which runs according to its interval. For example, if you set a
schedule to create a pipeline every minute (
* * * * *) and the Sidekiq worker
runs on 00:00 and 12:00 every day (
0 */12 * * *), only 2 pipelines will be
created per day. To change the Sidekiq worker's frequency, you have to edit the
pipeline_schedule_worker_cron value in your
gitlab.rb and restart GitLab.
For GitLab.com, you can check the dedicated settings page. If you
don't have admin access to the server, ask your administrator.
