Programar e executar um cron job usando a CLI gcloud
Neste guia de início rápido, mostramos como usar a CLI gcloud para realizar algumas operações básicas com o Cloud Scheduler.
Neste guia de início rápido, você fará as seguintes tarefas:
Crie um tópico do Pub/Sub para configurar como destino do job do Cloud Scheduler.
Crie um cron job usando o Cloud Scheduler e configure uma programação recorrente para ele.
Execute o job.
Verificar se o job foi concluído com sucesso.
O Cloud Scheduler tem um nível gratuito. Não convém executar este guia de início rápido.

Um tópico do Pub/Sub é um recurso em que os editores podem enviar mensagens.
Para receber as mensagens publicadas em um tópico, você precisa criar uma inscrição nele.
Configure um tópico do Pub/Sub para usar como destino do cron job:
gcloudpubsubtopicscreatecron-topic
Isso criará um tópico chamado cron-topic.
Para receber mensagens e ver os resultados do job, crie uma
assinatura do Pub/Sub:
Use o comando gcloud scheduler jobs create pubsub
para configurar uma unidade de trabalho conhecida como cron job, que é enviada a um
destino do Pub/Sub em uma programação recorrente. A programação é especificada
usando um formato baseado em unix-cron. Para mais informações, consulte
Formato de cron job e fuso horário.

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. For more information, see\n[Cron job format and time zone](/scheduler/docs/configuring/cron-job-schedules). \n\n gcloud scheduler jobs create pubsub my-cron-job \\\n --schedule=\"30 16 * * 7\" \\\n --topic=cron-topic \\\n --location=\"us-central1\" \\\n --message-body=\"Hello world\"\n\nYou've created a job that sends a \"Hello world\" message to your Pub/Sub\ntopic at 16:30 on Sundays.\n\nYou can now run the job.\n\nRun your job\n------------\n\nIn addition to executing according to its specified schedule, you can force your\njob to run immediately: \n\n gcloud scheduler jobs run my-cron-job --location=\"us-central1\"\n\nNote that due to some initial configuration, the first job created in a\nproject can take a few minutes to run.\n\nNext, you can verify that your Pub/Sub topic received the message.\n\nVerify the results in Pub/Sub\n-----------------------------\n\nVerify that your Pub/Sub topic is receiving messages from your job.\n\n1. 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. In Cloud Shell or on the\n machine where you installed the gcloud CLI, run the command:\n\n gcloud pubsub topics delete \u003cvar translate=\"no\"\u003eTOPIC_ID\u003c/var\u003e\n\n Replace \u003cvar translate=\"no\"\u003eTOPIC_ID\u003c/var\u003e with the ID of the\n Pub/Sub topic to be deleted.\n3. Delete the Pub/Sub subscription. In Cloud Shell or on\n the machine where you installed the gcloud CLI, run the command:\n\n gcloud pubsub subscriptions delete \u003cvar translate=\"no\"\u003eSUBSCRIPTION_ID\u003c/var\u003e\n\n Replace \u003cvar translate=\"no\"\u003eSUBSCRIPTION_ID\u003c/var\u003e with the ID of the\n Pub/Sub subscription to be deleted.\n\nWhat's next\n-----------\n\n- Learn more about [Cloud Scheduler](/scheduler/docs/overview)\n\n- Learn how to\n [view Cloud Scheduler logs](/scheduler/docs/viewing-logs)"]]
