Hantera Azure Cosmos DB för NoSQL-resurser med terraform
GÄLLER FÖR: 
NoSQL
I den här artikeln får du lära dig hur du använder terraform för att distribuera och hantera dina Azure Cosmos DB-konton, databaser och containrar.
Den här artikeln visar terraform-exempel för NoSQL-konton.
Viktigt!
- Kontonamn är begränsade till 44 tecken, alla gemener.
- Om du vill ändra dataflödesvärdena (RU/s) distribuerar du om terraform-filen med uppdaterade RU/s.
- När du lägger till eller tar bort platser till ett Azure Cosmos-konto kan du inte ändra andra egenskaper samtidigt. Dessa åtgärder måste utföras separat.
- Om du vill etablera dataflöde på databasnivå och dela över alla containrar tillämpar du dataflödesvärdena på egenskapen databasalternativ.
Om du vill skapa någon av Azure Cosmos DB-resurserna nedan kopierar du exemplet till en ny terraform-fil (main.tf) eller har två separata filer för resurser (main.tf) och variabler (variables.tf). Se till att inkludera azurerm-providern antingen i huvud terraform-filen eller dela upp till en separat providerfil. Alla exempel finns på terraform-exempellagringsplatsen.
terraform {
required_version = ">= 1.0"

azurerm = {
source = "hashicorp/azurerm"

}
}
}
