Schedule and run a cron job using the gcloud CLI
This quickstart shows you how to use the gcloud CLI to perform some
basic operations using Cloud Scheduler.
In this quickstart, you:
Create a Pub/Sub topic to set up as your Cloud Scheduler
job target.
Create a cron job using Cloud Scheduler, and configure a recurring
schedule for the job.
Run your job.
Verify that the job has run successfully.
Cloud Scheduler has a free tier and running this quickstart shouldn't
incur any costs. For more information, seePricing.

A Pub/Sub topic is a resource to which publishers can send messages.
To receive messages published to a topic, you must create a subscription to
that topic.
Set up a Pub/Sub topic to use as a target for your cron job:
gcloudpubsubtopicscreatecron-topic
This creates a topic calledcron-topic.
To receive messages and view the results of your job, create a
Pub/Sub subscription:
Use thegcloud scheduler jobs create pubsubcommand to set up a unit of work known as acron jobthat is sent to a
Pub/Sub target on a recurring schedule. The schedule is specified
using a format based on unix-cron. For more information, seeCron job format and time zone.

Set up a Pub/Sub topic to use as a target for your cron job:\n\n gcloud pubsub topics create cron-topic\n\n This creates a topic called `cron-topic`.\n2. To receive messages and view the results of your job, create a\n Pub/Sub subscription:\n\n gcloud pubsub subscriptions create cron-sub --topic cron-topic\n\nCreate a cron job using Cloud Scheduler\n---------------------------------------\n\nUse the [`gcloud scheduler jobs create pubsub`](/sdk/gcloud/reference/scheduler/jobs/create/pubsub)\ncommand to set up a unit of work known as a *cron job* that is sent to a\nPub/Sub target on a recurring schedule. The schedule is specified\nusing a format based on unix-cron.

Pull Pub/Sub messages from a subscription:\n\n gcloud pubsub subscriptions pull cron-sub --limit 5\n\n If there are no messages pulled initially, run the command again.\n2. View the results of running your job. The output should look similar to the\n following:\n\n DATA: Hello world!\n MESSAGE_ID: 5028933846601543\n ORDERING_KEY:\n ATTRIBUTES:\n DELIVERY_ATTEMPT:\n ACK_ID: RFAGFixdRkhRNxkIaFEOT14jPzUgKEUQAgVPAihdeTFXLkFacGhRDRlyfWB9[...]\n\nClean up\n--------\n\n\nTo avoid incurring charges to your Google Cloud account for\nthe resources used on this page, delete the Google Cloud project with the\nresources.\n\n| **Caution** : Deleting a project has the following effects:\n|\n| - **Everything in the project is deleted.** If you used an existing project for the tasks in this document, when you delete it, you also delete any other work you've done in the project.\n| - **Custom project IDs are lost.** When you created this project, you might have created a custom project ID that you want to use in the future. To preserve the URLs that use the project ID, such as an `appspot.com` URL, delete selected resources inside the project instead of deleting the whole project.\n|\n|\n| If you plan to explore multiple architectures, tutorials, or quickstarts, reusing projects\n| can help you avoid exceeding project quota limits.\n1. Delete a Google Cloud project: \n\n```\ngcloud projects delete PROJECT_ID\n```\n\n\u003cbr /\u003e\n\nAlternatively, delete the resources you created for this quickstart:\n\n1. Delete the cron job. In Cloud Shell or on the machine where you installed\n the gcloud CLI, run the command:\n\n gcloud scheduler jobs delete \u003cvar translate=\"no\"\u003eMY_JOB\u003c/var\u003e \\\n --location=\"\u003cvar translate=\"no\"\u003eLOCATION\u003c/var\u003e\"\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003eMY_JOB\u003c/var\u003e: the name of the job to be deleted.\n - \u003cvar translate=\"no\"\u003eLOCATION\u003c/var\u003e: the location of the job. By default, uses the location of the current project's App Engine app if there is an associated app.\n2. Delete the Pub/Sub topic.
