Verwalten von Ressourcen für Azure Cosmos DB for NoSQL mit Terraform

Artikel
06/01/2023

GILT FÜR: NoSQL

In diesem Artikel erfahren Sie, wie Sie Ihre Azure Cosmos DB-Konten, -Datenbanken und -Container mithilfe von Terraform bereitstellen und verwalten.

In diesem Artikel werden Terraform-Beispiele für NoSQL-Konten gezeigt.

Wichtig

Die Länge von Kontonamen ist auf 44 Zeichen (ausschließlich Kleinbuchstaben) beschränkt.
Sie müssen die Terraform-Datei mit einer aktualisierten Angabe der RU/s erneut bereitstellen, um die Durchsatzwerte (RU/s) ändern zu können.
Wenn Sie einem Azure Cosmos-Konto Speicherorte hinzufügen oder aus ihm entfernen, können Sie nicht gleichzeitig andere Eigenschaften ändern. Diese Vorgänge müssen separat ausgeführt werden.
Wenn Sie Durchsatz auf Datenbankebene bereitstellen und für alle Container freigeben möchten, wenden Sie die Durchsatzwerte auf die Eigenschaft „Datenbankoptionen“ an.

Um eine der folgenden Azure Cosmos DB-Ressourcen zu erstellen, kopieren Sie das Beispiel in eine neue Terraform-Datei (main.tf) oder alternativ zwei separate Dateien für Ressourcen (main.tf) und Variablen (variables.tf). Achten Sie darauf, den AzureRM-Anbieter entweder in die Haupt-Terraform-Datei einzuschließen oder in einer separaten Anbieterdatei unterzubringen. Alle Beispiele finden Sie im Terraform-Beispielrepository.

terraform {
  required_version = ">= 1.0"

  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = ">= 3.0, < 4.0"
    }
    random = {
      source  = "hashicorp/random"
      version = ">= 3.0"
    }
  }
}

provider "azurerm" {
  features {}
}
