Criar e executar um modelo Flex

Os modelos Flex do Dataflow permitem que você empacote um pipeline do Dataflow para implementação. Neste tutorial, mostramos como criar um modelo Flex do Dataflow e executar um job do Dataflow usando esse modelo.

Objetivos

• Criar um modelo Flex do Dataflow.
• Use o modelo para executar um job do Dataflow.

Custos

Neste documento, você usará os seguintes componentes faturáveis do Google Cloud:

• Dataflow
• Cloud Storage
• Artifact Registry
• Cloud Build

Para gerar uma estimativa de custo baseada na projeção de uso deste tutorial, use a calculadora de preços. Novos usuários do Google Cloud podem estar qualificados para uma avaliação gratuita.

Ao concluir as tarefas descritas neste documento, é possível evitar o faturamento contínuo excluindo os recursos criados. Saiba mais em Limpeza.

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. To initialize the gcloud CLI, run the following command:

   gcloud init

4. 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.

5. Make sure that billing is enabled for your Google Cloud project.

6. Enable the Dataflow, Compute Engine, Logging, Cloud Storage, Cloud Storage JSON, Resource Manager, Artifact Registry, and Cloud Build API:

   gcloud services enable dataflow compute_component logging storage_component storage_api cloudresourcemanager.googleapis.com artifactregistry.googleapis.com cloudbuild.googleapis.com

7. 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.

8. Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/iam.serviceAccountUser

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

   • Replace PROJECT_ID with your project ID.

   • Replace USER_IDENTIFIER with the identifier for your user account. For example, user:myemail@example.com.

   • Replace ROLE with each individual role.
9. Install the Google Cloud CLI.

10. To initialize the gcloud CLI, run the following command:

    gcloud init

11. 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.

12. Make sure that billing is enabled for your Google Cloud project.

13. Enable the Dataflow, Compute Engine, Logging, Cloud Storage, Cloud Storage JSON, Resource Manager, Artifact Registry, and Cloud Build API:

    gcloud services enable dataflow compute_component logging storage_component storage_api cloudresourcemanager.googleapis.com artifactregistry.googleapis.com cloudbuild.googleapis.com

14. 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.

15. Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/iam.serviceAccountUser

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

    • Replace PROJECT_ID with your project ID.

    • Replace USER_IDENTIFIER with the identifier for your user account. For example, user:myemail@example.com.

    • Replace ROLE with each individual role.

16. Conceda papéis à conta de serviço padrão do Compute Engine. Execute uma vez o comando a seguir para cada um dos seguintes papéis do IAM:

    • roles/dataflow.admin
    • roles/dataflow.worker
    • roles/storage.objectAdmin
    • roles/artifactregistry.writer

    gcloud projects add-iam-policy-binding PROJECT_ID --member="serviceAccount:PROJECT_NUMBER-compute@developer.gserviceaccount.com" --role=SERVICE_ACCOUNT_ROLE

    Substitua:

    • PROJECT_ID: ID do projeto;
    • PROJECT_NUMBER: o número do projeto
    • SERVICE_ACCOUNT_ROLE: cada papel individual

Limpar

Para evitar cobranças na sua conta do Google Cloud pelos recursos usados no tutorial, exclua o projeto que os contém ou mantenha o projeto e exclua os recursos individuais.

Excluir o projeto

Delete a Google Cloud project:

gcloud projects delete PROJECT_ID

Excluir recursos individuais

1. Exclua o bucket do Cloud Storage e todos os objetos nele.

   gcloud storage rm gs://BUCKET_NAME --recursive

2. Exclua o repositório do Artifact Registry.

   gcloud artifacts repositories delete REPOSITORY \
       --location=LOCATION

3. Revogar os papéis concedidos à conta de serviço padrão do Compute Engine. Execute uma vez o seguinte comando para cada um dos seguintes papéis do IAM:
   • roles/dataflow.admin
   • roles/dataflow.worker
   • roles/storage.objectAdmin
   • roles/artifactregistry.writer

   gcloud projects remove-iam-policy-binding PROJECT_ID \
       --member=serviceAccount:PROJECT_NUMBER-compute@developer.gserviceaccount.com \
       --role=SERVICE_ACCOUNT_ROLE

4. Optional: Revoke the authentication credentials that you created, and delete the local credential file.

   gcloud auth application-default revoke

5. Optional: Revoke credentials from the gcloud CLI.

   gcloud auth revoke
