Scheduler for VMware Tanzu is a scheduler service exposed as a service broker in the VMware Marketplace. App developers use Scheduler to create, schedule, and interact with jobs that execute on VMware Tanzu Application Service. It allows scheduling the execution of Diego tasks (jobs), such as database migrations, emails, or batch jobs, and the execution of outbound HTTP requests (calls).
You can:
- Create jobs to execute tasks (Diego tasks).
- Execute jobs on an ad hoc basis.
- Schedule jobs to execute on a recurring basis.
- View job status and history.
You can interact with the service by using the Cloud Foundry Command Line Interface (cf CLI), Apps Manager, and the Scheduler HTTP API.

Limitations
-
If your app uses a buildpack that does not generate a
webprocess type, such as Ruby or Python, you should do the following:- Create a Procfile in the root directory of the app before pushing it.
- Declare a
webprocess type in the file.
If you do not declare this process type, your app is not accessible when using the cf CLI after you create Scheduler jobs for it.
-
The maximum number of tasks that you can schedule is determined by the memory, disk, and log rate quotas in the Scheduler org and space. For more information, see Running tasks.
