Using Scheduler for PCF
This topic provides instructions for using Scheduler for Pivotal Cloud Foundry (PCF).
You can interact with the service through the Cloud Foundry Command Line Interface (cf CLI), Apps Manager, and the Scheduler HTTP API to configure jobs and outbound HTTP calls and to review history. For general information, see Managing Service Instances with the cf CLI.
To start using Scheduler for PCF, you need the following:
- A PCF deployment with Scheduler for PCF installed and listed in the Marketplace.
- A Space Developer account.
- (Optional) The cf CLI v6.23.0 or greater and the Scheduler for PCF CLI plugin installed on your local machine. The Scheduler for PCF CLI plugin is packaged with the Scheduler for PCF tile on Pivotal Network.
Every app and service in PCF is scoped to a space. This means that an app can use a service only if an instance of the service exists in the same space.
The Scheduler for PCF service is a singleton service. Only one service instance can be created in a space.
For apps to use a service, the service must be available in the Marketplace. To confirm the availability of Scheduler for PCF, perform the following steps:
cf marketplacefrom the command line.
If the output lists
servicecolumn, Scheduler for PCF is available. If the service is not available, install it. See Installing and Configuring Scheduler for PCF for more information.
$ cf marketplace Getting services from marketplace in org my-org / space my-space as firstname.lastname@example.org... OK service plans description [...] scheduler-for-pcf standard Scheduler service [...]
To create an instance of the Scheduler for PCF service, run
cf create-service scheduler-for-pcf standard SERVICE-INSTANCE-NAME, replacing
SERVICE-INSTANCE-NAME with a name of your choice. After you create the service instance, this instance name appears under
name in the output of the
cf services command.
See the following example:
$ cf create-service scheduler-for-pcf standard my-instance
Creating service my-instance in org my-org / space my-space as email@example.com... OK
$ cf services
Getting services in org my-org / space my-space as firstname.lastname@example.org... OK name service plan bound apps last operation my-instance scheduler-for-pcf standard create succeeded
You can create only one instance in a space. If you attempt to create more than one instance in a space, you receive an error response.
For an app to use a service, you must bind it to a service instance. Do this after you push or re-push the app using
To bind an app to a Scheduler for PCF instance, run
cf bind-service APP-NAME SERVICE-INSTANCE-NAME, replacing
APP-NAME with the name of the app you want to use the Scheduler for PCF service for and
SERVICE-INSTANCE-NAME with the name you provided when you ran
$ cf bind-service my-app my-instance
Binding service my-instance to my-app in org my-org / space my-space as email@example.com... OK TIP: Use 'cf push' to ensure your env variable changes take effect
If you want to manage jobs and calls through the Scheduler HTTP API, see the Scheduler for PCF API Documentation.
