Gestire le risorse di utilizzo del servizio con Terraform
Questo documento descrive come eseguire il provisioning delle risorse di Service Usage, come le sostituzioni delle quote, utilizzando Terraform.
Per gestire le sostituzioni delle quote consumer, puoi utilizzare lo schema google_service_usage_consumer_quota_override per specificare le risorse nel file di configurazione Terraform ed eseguire i comandi Terraform per applicare la modifica.
Prima di iniziare
Esamina il modello di quota del servizio che descrive la terminologia utilizzata in questo tutorial.
Configura Terraform e le credenziali:
Installa Google Cloud SDK.
Crea le credenziali predefinite dell'applicazione:
gcloud auth application-default login
Creare sostituzioni della quota consumer
Crea il file di configurazione:
Vai alla tua directory di lavoro.
Copia e incolla i seguenti contenuti in un nuovo file denominato 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 }I contenuti inseriti nel file
main.tfcontengono le informazioni di configurazione per due sostituzioni dei consumatori:"regional_override"e"cd_override". Per le spiegazioni di ciascun campo, consulta la documentazione di riferimento degli argomenti.Inizializza la directory di lavoro.
terraform init -upgradeApplica la configurazione Terraform.
terraform applyTerraform ispeziona lo stato attuale e lo confronta con le informazioni nel file di configurazione. Al termine del confronto, Terraform stampa un elenco di modifiche e fornisce le opzioni per procedere o annullare l'applicazione delle modifiche.

Modificare le sostituzioni della quota consumer
- Per modificare una sostituzione, modifica il file
main.tfe cambia il valore di un campooverride_value. Applica la configurazione Terraform.
terraform apply
Eliminare le sostituzioni della quota consumer
Per eliminare una sostituzione della quota del consumatore, rimuovi il blocco di risorse corrispondente dal file main.tf. Puoi rimuovere più sostituzioni. Per rimuovere tutte le sostituzioni, assicurati che il file main.tf sia vuoto.
Applica la configurazione Terraform.
terraform applyAd esempio, per eliminare l'override regionale di cui hai eseguito il provisioning in precedenza. Elimina il blocco che fa riferimento alla risorsa:
resource "google_service_usage_consumer_quota_override" "regional_override" { ... }L'output dopo

File di stato
Potresti notare che nella tua directory di lavoro sono presenti due file generati: terraform.tfstate e terraform.tfstate.backup. Il primo file registra lo stato attuale dell'infrastruttura dopo l'esecuzione dell'ultima versione di terraform apply. Il secondo file registra lo stato precedente all'ultima terraform apply. Per ulteriori informazioni sullo stato di Terraform, consulta la documentazione ufficiale.
Se hai seguito finora i passaggi descritti in questa pagina, i seguenti contenuti sono nel file terraform.tfstate, con cd_override rimasto nella nostra infrastruttura.
