Terraform - Add tags to failover SQL databases - terraform

Question

I am trying to figure out a way to add tags to the failover DBs created with the help of terraform registry - azurerm_mssql_failover_group.
if I use the tags field mentioned as part of terraform documentation, it adds tags to the failover group but it does not set tags on the failover databases created.
My code for the resource group is as below
resource "azurerm_mssql_failover_group" "sql-database-failover" {
name = "sqldatabasefailover1"
server_id = "Id of Primary SQL Server"
databases = [
"Id of primary SQL dbs"
]
partner_server {
id = "Id of secondary (failover) SQL server"
}
read_write_endpoint_failover_policy {
mode = "Automatic"
grace_minutes = 60
}
tags = local.common_tags
}
I tried looking for terraform registry which can help us add tags to the already present DB but could not find any. Any help will be appreciated.

Answer 1

I tried to reproduce the same in my environment .
I created local tags as below and tried to add to failover group.
Code referred from : azurerm_sql_failover_group | Resources | hashicorp/azurerm | Terraform Registry
Code:
locals {
resource_tags = {
project_name = "failovergroup",
category = "devbackupresource"
}
}
resource "azurerm_mssql_server" "primary" {
name = "ka-sql-primary"
resource_group_name = data.azurerm_resource_group.example.name
location = "southeastasia"
version = "12.0"
administrator_login = "sqladmin"
administrator_login_password = "xxx"
}
resource "azurerm_mssql_server" "secondary" {
name = "ka-sql-secondary"
resource_group_name = data.azurerm_resource_group.example.name
location = "westeurope"
version = "12.0"
administrator_login = "sqladmin"
administrator_login_password = "xxx"
}
resource "azurerm_mssql_database" "db1" {
name = "kadb1"
server_id = azurerm_mssql_server.primary.id
}
resource "azurerm_mssql_failover_group" "example" {
name = "kav-example-failover-group"
server_id = azurerm_mssql_server.primary.id
databases = [azurerm_mssql_database.db1.id]
tags = local.resource_tags
partner_server {
id = azurerm_mssql_server.secondary.id
}
read_write_endpoint_failover_policy {
mode = "Automatic"
grace_minutes = 60
}
}
But the tags are not added to secondaryDb which is intended for failover group.
You can use the tags in Secondary Db resource block ” azurerm_mssql_server” for secondary as below.
locals {
resource_tags = {
...
}
}
resource "azurerm_mssql_server" "secondary" {
name = "ka-sql-secondary"
resource_group_name = data.azurerm_resource_group.example.name
location = "westeurope"
version = "12.0"
administrator_login = "sqladmin"
administrator_login_password = "pa$$w0rd"
tags = local.resource_tags
}
resource "azurerm_mssql_failover_group" "example" {
name = "kav-example-failover-group
server_id = azurerm_mssql_server.primary.id
databases = [azurerm_mssql_database.db1.id]
...
}
This created tags to my secondary sql server in azure .
Edit:
tag-support-microsoftsql
See Auto-failover groups limitations .One may need to create tags manually .
Also Note: Database restore operations don't restore the tags of the
original database.
