i am trying to create mysql with some default configurations on azure with terraform, following is my code. although "enforce_gtid_consistency" and "time_zone" is working and being created, but "gtid_mode" "ON" isn't working I am getting following error.
resource "azurerm_mysql_server" "main" {
name = var.mysql_server_name != "" ? var.mysql_server_name : "mysql-01-${var.instancesuffix}"

Answer 1

As I have mentioned in comment , The gtid_mode can only be enabled in sequence , directly turning ON will not work evenif the dependency is set with enforce_gtid_consistency.
So, as a solution you have to set it up in sequence:
OFF_PERMISSIVE
ON_PERMISSIVE
ON
I tested with your code doing some changes as below:
main.tf
provider "azurerm"{
features{}
}
data "azurerm_resource_group" "main"{
name = "resourcegroup"
}
data "azurerm_key_vault" "kv"{
name = "ansumantestkv1234"
resource_group_name = "resourcegroup"
}
data "azurerm_key_vault_secret" "name" {
name = "mysqlpassword"
key_vault_id = data.azurerm_key_vault.kv.id
}
resource "azurerm_mysql_server" "main" {
name = var.mysql_server_name
location = data.azurerm_resource_group.main.location
resource_group_name = data.azurerm_resource_group.main.name
administrator_login = var.mysql_administrator_login
administrator_login_password = data.azurerm_key_vault_secret.name.value
sku_name = var.mysql_sku_name
storage_mb = var.mysql_storage_mb
version = var.mysql_version
auto_grow_enabled = true
backup_retention_days = 7
geo_redundant_backup_enabled = false
infrastructure_encryption_enabled = true
public_network_access_enabled = true
ssl_enforcement_enabled = true
ssl_minimal_tls_version_enforced = "TLS1_2"
threat_detection_policy {
disabled_alerts = []
email_account_admins = false
email_addresses = []
enabled = true
retention_days = 0
}
}
resource "azurerm_mysql_configuration" "time_zone" {
name = "time_zone"
resource_group_name = data.azurerm_resource_group.main.name
server_name = azurerm_mysql_server.main.name
value = "+00:00"
}
resource "azurerm_mysql_configuration" "enforce_gtid_consistency" {
name = "enforce_gtid_consistency"
resource_group_name = data.azurerm_resource_group.main.name
server_name = azurerm_mysql_server.main.name
value = "ON"
depends_on = [
azurerm_mysql_configuration.time_zone
]
}
resource "azurerm_mysql_configuration" "gtid_mode_OFF_permissive" {
name = "gtid_mode"
resource_group_name = data.azurerm_resource_group.main.name
server_name = azurerm_mysql_server.main.name
value = "OFF_PERMISSIVE"
depends_on = [
azurerm_mysql_configuration.enforce_gtid_consistency,
]
}
resource "azurerm_mysql_configuration" "gtid_mode_ON_Permissive" {
name = "gtid_mode"
resource_group_name = data.azurerm_resource_group.main.name
server_name = azurerm_mysql_server.main.name
value = "ON_PERMISSIVE"
depends_on = [
azurerm_mysql_configuration.gtid_mode_OFF_permissive
]
}
resource "azurerm_mysql_configuration" "gtid_mode_ON" {
name = "gtid_mode"
resource_group_name = data.azurerm_resource_group.main.name
server_name = azurerm_mysql_server.main.name
value = "ON"
depends_on = [
azurerm_mysql_configuration.gtid_mode_ON_Permissive
]
}
variable.tf:
variable "mysql_server_name" {
default = "ansumanmysqlserver"
}
variable "mysql_administrator_login" {
default = "ansuman"
}
variable "mysql_sku_name" {
default = "GP_Gen5_2"
}
variable "mysql_storage_mb" {
default = "5120"
}
variable "mysql_version" {
default = "5.7"
}
