Adicionar uma tarefa de destino HTTP a uma fila do Cloud Tasks

Neste guia de início rápido, mostramos como adicionar uma tarefa de destino HTTP a uma fila do Cloud Tasks usando a API Cloud Tasks.

Antes de começar

  1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.

  2. Install the Google Cloud CLI.

  3. Se você estiver usando um provedor de identidade externo (IdP), primeiro faça login na CLI gcloud com sua identidade federada.

  4. Para inicializar a CLI gcloud, execute o seguinte comando: 

    gcloud init

  5. Create or select a Google Cloud project.

    • Create a Google Cloud project:

      gcloud projects create PROJECT_ID

      Replace PROJECT_ID with a name for the Google Cloud project you are creating.

    • Select the Google Cloud project that you created:

      gcloud config set project PROJECT_ID

      Replace PROJECT_ID with your Google Cloud project name.

  6. Verify that billing is enabled for your Google Cloud project.

  7. Enable the Cloud Tasks API: 

    gcloud services enable cloudtasks.googleapis.com

  8. If you're using a local shell, then create local authentication credentials for your user account: 

    gcloud auth application-default login

    You don't need to do this if you're using Cloud Shell.

    If an authentication error is returned, and you are using an external identity provider (IdP), confirm that you have signed in to the gcloud CLI with your federated identity.

  9. Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/cloudtasks.admin, roles/logging.viewer 

    gcloud projects add-iam-policy-binding PROJECT_ID --member="user:USER_IDENTIFIER" --role=ROLE

    Replace the following:

    • PROJECT_ID: your project ID.
    • USER_IDENTIFIER: the identifier for your user account—for example, myemail@example.com.
    • ROLE: the IAM role that you grant to your user account.

  10. Install the Google Cloud CLI.

  11. Se você estiver usando um provedor de identidade externo (IdP), primeiro faça login na CLI gcloud com sua identidade federada.

  12. Para inicializar a CLI gcloud, execute o seguinte comando: 

    gcloud init

  13. Create or select a Google Cloud project.

    • Create a Google Cloud project:

      gcloud projects create PROJECT_ID

      Replace PROJECT_ID with a name for the Google Cloud project you are creating.

    • Select the Google Cloud project that you created:

      gcloud config set project PROJECT_ID

      Replace PROJECT_ID with your Google Cloud project name.

  14. Verify that billing is enabled for your Google Cloud project.

  15. Enable the Cloud Tasks API: 

    gcloud services enable cloudtasks.googleapis.com

  16. If you're using a local shell, then create local authentication credentials for your user account: 

    gcloud auth application-default login

    You don't need to do this if you're using Cloud Shell.

    If an authentication error is returned, and you are using an external identity provider (IdP), confirm that you have signed in to the gcloud CLI with your federated identity.

  17. Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/cloudtasks.admin, roles/logging.viewer 

    gcloud projects add-iam-policy-binding PROJECT_ID --member="user:USER_IDENTIFIER" --role=ROLE

    Replace the following:

    • PROJECT_ID: your project ID.
    • USER_IDENTIFIER: the identifier for your user account—for example, myemail@example.com.
    • ROLE: the IAM role that you grant to your user account.
    18.

    Criar uma fila do Cloud Tasks

    Use o comando gcloud tasks queues create para criar sua fila.

    1. No terminal, crie uma fila que registre todas as operações.

      gcloud tasks queues create QUEUE_NAME \
    --log-sampling-ratio=1.0 \
    --location=REGION

      Substitua:

      • QUEUE_NAME: um nome para sua fila do Cloud Tasks
      • REGION: a região compatível em que você implantou o serviço ou app

    2. Aguarde a inicialização da fila e verifique se ela foi criada com sucesso.

      gcloud tasks queues describe QUEUE_NAME \
    --location=REGION

      A saída será semelhante a esta:

       name: projects/PROJECT_ID/locations/LOCATION_ID/queues/QUEUE_NAME
 rateLimits:
   maxBurstSize: 100
   maxConcurrentDispatches: 1000
   maxDispatchesPerSecond: 500.0
 retryConfig:
   maxAttempts: 100
   maxBackoff: 3600s
   maxDoublings: 16
   minBackoff: 0.100s
 state: RUNNING

    Adicionar uma tarefa à fila do Cloud Tasks

    Use o comando gcloud tasks create-http-task para criar uma tarefa que tenha como destino um endpoint HTTP e adicione a tarefa à sua fila.

    1. Crie uma tarefa, adicione-a à fila criada e entregue-a a um endpoint HTTP.

      gcloud tasks create-http-task \
    --queue=QUEUE_NAME \
    --url=URL_PATH \
    --method=GET \
    --location=REGION \
    --project=PROJECT_ID

      Substitua URL_PATH pelo caminho completo do URL para onde a solicitação será enviada. Por exemplo: https://www.google.com

      O caminho precisa começar com http:// ou https://.

    2. Verifique se a tarefa foi executada com sucesso lendo os registros.

      gcloud logging read --limit=3

      Os registros serão semelhantes a este:

      jsonPayload:
'@type': type.googleapis.com/google.cloud.tasks.logging.v1.TaskActivityLog
task: projects/PROJECT_ID/locations/REGION/queues/QUEUE_NAME/tasks/TASK_ID
taskCreationLog:
   scheduleTime: '2024-07-04T19:00:27.801837Z'
   status: OK
   targetAddress: GET https://www.google.com/
   targetType: HTTP

    Limpar

    Para evitar cobranças na sua conta do Google Cloud pelos recursos usados nesta página, exclua o projeto do Google Cloud com os recursos.

    Delete a Google Cloud project:

    gcloud projects delete PROJECT_ID

    Se preferir, exclua a fila do Cloud Tasks:

    gcloud tasks queues delete QUEUE_NAME \
    --location=REGION
