Gerenciar recursos do Service Usage com o Terraform
Neste documento, descrevemos como provisionar recursos do Service Usage, como substituições de cotas, usando o Terraform.
Para gerenciar substituições de cota do consumidor, use o esquema google_service_usage_consumer_quota_override para especificar recursos no arquivo de configuração do Terraform e execute os comandos do Terraform para aplicar a mudança.
Antes de começar
Consulte o modelo de cota de serviço, que descreve a terminologia usada neste tutorial.
Configure o Terraform e as credenciais:
Instale o SDK do Google Cloud.
Crie as credenciais padrão do aplicativo:
gcloud auth application-default login
Criar substituições de cota do consumidor
Crie o arquivo de configuração:
Navegue até o diretório de trabalho.
Copie e cole o conteúdo abaixo em um novo arquivo chamado main.tf.
resource "google_service_usage_consumer_quota_override" "regional_override" { provider = google-beta dimensions = { region = "us-central1" } project = PROJECT_ID service = "libraryagent.googleapis.com" metric = "libraryagent.googleapis.com%2Fread_requests_regional" limit = "%2Fmin%2Fproject%2Fregion" override_value = "8" force = true } resource "google_service_usage_consumer_quota_override" "cd_override" { provider = google-beta dimensions = { author = "larry" } project = PROJECT_ID service = "libraryagent.googleapis.com" metric = "libraryagent.googleapis.com%2Fborrows" limit = "%2Fauthor%2Fproject" override_value = "8" force = true }O conteúdo colocado no arquivo
main.tfcontém as informações de configuração de duas substituições de consumidor:"regional_override"e"cd_override". Consulte a Referência de argumentos sobre as explicações de cada campo.Inicialize o diretório de trabalho.
terraform init -upgradeAplique a configuração do Terraform.
terraform applyO Terraform inspeciona o estado atual e o compara com as informações no arquivo de configuração. Depois que a comparação for concluída, o Terraform vai mostrar uma lista de mudanças e oferecer opções para prosseguir ou cancelar a aplicação das mudanças.

Modificar substituições de cota do consumidor
- Para modificar uma substituição, edite o arquivo
main.tfe mude o valor de um campooverride_value. Aplique a configuração do Terraform.
terraform apply
Excluir substituições de cota do consumidor
Para excluir uma modificação de cota do consumidor, remova o bloco de recursos correspondente do arquivo main.tf. É possível remover várias substituições. Para remover todas as substituições, verifique se o arquivo main.tf está vazio.
Aplique a configuração do Terraform.
terraform applyPor exemplo, para excluir a substituição regional que você provisionou anteriormente. Exclua o bloco que se refere ao recurso:
resource "google_service_usage_consumer_quota_override" "regional_override" { ... }A saída após

Arquivos de estado
Observe que há dois arquivos gerados no seu diretório de trabalho: terraform.tfstate e terraform.tfstate.backup. O primeiro arquivo registra o estado atual da infraestrutura depois que você executa o terraform apply mais recente. O segundo arquivo registra o estado anterior ao terraform apply mais recente. Para mais informações sobre o estado do Terraform, consulte a documentação oficial.
Se você seguiu as etapas desta página até agora, o conteúdo a seguir está no arquivo terraform.tfstate, com o cd_override à esquerda na nossa infraestrutura.
