Azure MySQL Flexible Server

Terrafom module to deploy a MySQL Flexible Server on Azure Cloud.

• Support standalone(one read-write instance) and replication(one read-write instance and multiple read-only instances, for read write splitting).

Usage

module "mysql" {
  source = "..."

  infrastructure = {
    resource_group  = "..."
    virtual_network = "..."
    subnet          = "..."
    domain_suffix   = "..."
  }

  resources = {
    class = "B_Standard_B1s"
  }

  storage = {
    size = 20480
  }
}

Examples

• Replication
• Standalone

Inputs

Name	Description	Type	Default	Required
architecture	Specify the deployment architecture, select from standalone or replication.	string	"standalone"	no
context	Receive contextual information. When Walrus deploys, Walrus will inject specific contextual information into this field. Examples: context: project: name: string id: string environment: name: string id: string resource: name: string id: string	map(any)	{}	no
database	Specify the database name. The database name must be 2-64 characters long and start with any lower letter, combined with number, or symbols: - _. The database name cannot be MySQL forbidden keyword.	string	"mydb"	no
engine_version	Specify the deployment engine version of the MySQL Flexible Server to use. Possible values are 5.7, and 8.0.21.	string	"8.0.21"	no
infrastructure	Specify the infrastructure information for deploying. Examples: infrastructure: resource_group: string, optional # the resource group name where to deploy the MySQL Flexible Server virtual_network: string, optional # the virtual network name where to deploy the MySQL Flexible Server subnet: string, optional # the subnet name under the virtual network where to deploy the MySQL Flexible Server domain_suffix: string, optional # a private DNS namespace of the PrivateZone where to register the applied MySQL service. It must end with 'mysql.database.azure.com'	object({ resource_group = optional(string) virtual_network = optional(string) subnet = optional(string) domain_suffix = optional(string) })	{}	no
password	Specify the account password. The password must be 8-128 characters long and start with any letter, number, or symbols: ! # $ % ^ & * ( ) _ + - =. If not specified, it will generate a random password.	string	null	no
replication_readonly_replicas	Specify the number of read-only replicas under the replication deployment.	number	1	no
resources	Specify the computing resources. The computing resource design of Azure Cloud is very complex, it also needs to consider on the storage resource, please view the specification document for more information. For example: B_Standard_B1s, GP_Standard_D2ads_v5 or BC_Standard_E2ds_v4 See https://learn.microsoft.com/en-us/azure/mysql/flexible-server/concepts-service-tiers-storage#service-tiers-size-and-server-types. Examples: resources: class: string, optional # sku	object({ class = optional(string, "B_Standard_B1s") })	{ "class": "B_Standard_B1s" }	no
storage	Choosing the storage resource is also related to the computing resource, please view the specification document for more information. Examples: storage: size: number, optional # in megabyte	object({ size = optional(number, 20 * 1024) })	{ "size": 20480 }	no
username	Specify the account username. The username must be 1-63 characters long and start with lower letter, combined with number. The username cannot be MySQL forbidden keyword and azure_superuser, admin, administrator, root, guest or public.	string	"rdsuser"	no
