Configure schedules for pipelines

TFS 2017 | TFS 2015

Note

In Microsoft Team Foundation Server (TFS) 2018 and previous versions, build and release pipelines are called definitions, runs are called builds, service connections are called service endpoints, stages are called environments, and jobs are called phases.

Azure Pipelines provides several types of triggers to configure how your pipeline starts.

• Scheduled triggers start your pipeline based on a schedule, such as a nightly build. This article provides guidance on using scheduled triggers to run your pipelines based on a schedule.
• Event-based triggers start your pipeline in response to events, such as creating a pull request or pushing to a branch. For information on using event-based triggers, see Triggers in Azure Pipelines.

You can combine scheduled and event-based triggers in your pipelines, for example to validate the build every time a push is made (CI trigger), when a pull request is made (PR trigger), and a nightly build (Scheduled trigger). If you want to build your pipeline only on a schedule, and not in response to event-based triggers, ensure that your pipeline does not have any other triggers enabled. For example, YAML pipelines in a GitHub repository have CI triggers and PR triggers enabled by default. For information on disabling default triggers, see Triggers in Azure Pipelines and navigate to the section that covers your repository type.

Scheduled triggers

YAML

YAML pipelines are not available on TFS 2017.

Classic

Select the days and times when you want to run the build using the classic editor.

If your repository is Azure Repos Git, GitHub, or Other Git, then you can also specify branches to include and exclude. If you want to use wildcard characters, then type the branch specification (for example, features/modules/*) and then press Enter.

Examples

YAML

YAML pipelines are not available on TFS 2017.

Classic

Example: Nightly build of Git repo in multiple time zones

Example: Nightly build with different frequencies

TFS 2017.3 through TFS 2018

TFS 2017.1 and older versions

Cron syntax

YAML

YAML pipelines are not available on TFS 2017.

Classic

Classic schedules are defined using a graphical editor instead of cron syntax. For information on defining classic schedules, see Examples.

Scheduled runs view

YAML

YAML pipelines are not available on TFS 2017.

Classic

Classic scheduled pipelines don't have a Scheduled runs view, but you can view the schedule for a pipeline in the classic schedule editor for your pipeline.

Running even when there are no code changes

Note

Scheduled builds always run on schedule regardless of code changes on TFS 2018.1 and lower.

Limits on the number of scheduled runs

There are certain limits on how often you can schedule a pipeline to run. These limits have been put in place to prevent misuse of Azure Pipelines resources, particularly the Microsoft-hosted agents. This limit is around 1000 runs per pipeline per week.
