arvancloud_dbaas_postgresql_primary_instance (Resource)

Manages a primary PostgreSQL database instance on Arvancloud DBaaS.

After create and after resize, the provider waits until the instance is ACTIVE and hasFirstFullBackup is true (up to ~45 minutes each). Changing flavor_ref or volume_size resizes the instance. Changing tags applies updates in place. Most other arguments force replacement when changed.

Example Usage​

resource "arvancloud_dbaas_postgresql_primary_instance" "example" {
  name               = "tf-postgresql-primary"
  availability_zone  = "ir-thr-ba1"
  flavor_ref         = "g2-4-2-0"
  datastore_version  = "17.3"
  volume_size        = 50
  tags               = ["tf", "postgresql"]
}

  • datastore_version (String) PostgreSQL engine version (e.g. 17.3).
  • flavor_ref (String) Flavor reference (e.g. g2-4-2-0). Updates call the resize API when this value changes.

  • created_at (String) Creation timestamp from the API (createDate).
  • datastore_engine (String) Always postgresql for this resource (API datastoreType).
  • engine_port (String) Database engine port.
  • flavor_cpu (Number) vCPU count from the provisioned flavor.
  • flavor_disk_gb (Number) Disk size in GB from the flavor object returned by the API.
  • flavor_iops (Number) IOPS from the provisioned flavor.
  • flavor_ram_gb (Number) RAM in GB from the provisioned flavor.
