It is possible to create the azure database for PostgreSQL flexible server backup using terraform
Please use the below terraform code to restore the server
provider "azurerm" {
features {}
}
resource "azurerm_resource_group" "example" {
name = "RG_NAME"
location = "EASTUS"
}
resource "azurerm_virtual_network" "example" {
name = "example-vn"
location = azurerm_resource_group.example.location
resource_group_name = azurerm_resource_group.example.name
address_space = ["10.0.0.0/16"]
}
resource "azurerm_subnet" "example" {
name = "example-sn"
resource_group_name = azurerm_resource_group.example.name
virtual_network_name = azurerm_virtual_network.example.name
address_prefixes = ["10.0.2.0/24"]
service_endpoints = ["Microsoft.Storage"]
delegation {
name = "fs"
service_delegation {
name = "Microsoft.DBforPostgreSQL/flexibleServers"
actions = [
"Microsoft.Network/virtualNetworks/subnets/join/action",
]
}
}
}
resource "azurerm_private_dns_zone" "example" {
name = "example.postgres.database.azure.com"
resource_group_name = azurerm_resource_group.example.name
}
resource "azurerm_private_dns_zone_virtual_network_link" "example" {
name = "exampleVnetZone.com"
private_dns_zone_name = azurerm_private_dns_zone.example.name
virtual_network_id = azurerm_virtual_network.example.id
resource_group_name = azurerm_resource_group.example.name
}
resource "azurerm_postgresql_flexible_server" "example" {
name = "example-psqlflexibleserver"
resource_group_name = azurerm_resource_group.example.name
location = azurerm_resource_group.example.location
version = "12"
delegated_subnet_id = azurerm_subnet.example.id
private_dns_zone_id = azurerm_private_dns_zone.example.id
administrator_login = "psqladmin"
administrator_password = "H@Sh1CoR3!"
zone = "1"
storage_mb = 32768
backup_retention_days = 30
geo_redundant_backup_enabled = true
sku_name = "GP_Standard_D4s_v3"
depends_on = [azurerm_private_dns_zone_virtual_network_link.example]
}
Here I have mentioned the RG_name, subnet, VM, Vnet, db name, password and backup policy days
I have given the backup policy retention days are 30 the policy retention days should be in between 1 to 35 and the defaults value is 7 days
Before running the script we have to check the appropriate login server details
After the follow the below steps to execute the file
terraform init
It will initialize the file
Terraform plan
This will creates an execution plan and it will preview the changes that terraform plans to make the infrastructure
Terraform apply
This will creates or updates the infrastructure depending on the configuration
Previously it was default and the geo_redundant_backup_enabled is false I have set it to true and backup policy will be 30 days
For reference you can use this documentation
