This module manages the creation of Cloud SQL instances with potential read replicas in other regions. It can also create an initial set of users and databases via the `users` and `databases` parameters.
Note that this module assumes that some options are the same for both the primary instance and all the replicas (e.g. tier, disks, labels, flags, etc).
| [activation_policy](variables.tf#L16) | This variable specifies when the instance should be active. Can be either ALWAYS, NEVER or ON_DEMAND. Default is ALWAYS. | <code>string</code> | | <code>"ALWAYS"</code> |
| [availability_type](variables.tf#L27) | Availability type for the primary replica. Either `ZONAL` or `REGIONAL`. | <code>string</code> | | <code>"ZONAL"</code> |
| [backup_configuration](variables.tf#L33) | Backup settings for primary instance. Will be automatically enabled if using MySQL with one or more replicas. | <codetitle="object({ enabled = optional(bool, false) binary_log_enabled = optional(bool, false) start_time = optional(string, "23:00") location = optional(string) log_retention_days = optional(number, 7) point_in_time_recovery_enabled = optional(bool) retention_count = optional(number, 7) })">object({…})</code> | | <codetitle="{ enabled = false binary_log_enabled = false start_time = "23:00" location = null log_retention_days = 7 point_in_time_recovery_enabled = null retention_count = 7 }">{…}</code> |
| [collation](variables.tf#L56) | The name of server instance collation. | <code>string</code> | | <code>null</code> |
| [connector_enforcement](variables.tf#L62) | Specifies if connections must use Cloud SQL connectors. | <code>string</code> | | <code>null</code> |
| [databases](variables.tf#L73) | Databases to create once the primary instance is created. | <code>list(string)</code> | | <code>null</code> |
| [deletion_protection_enabled](variables.tf#L86) | Set Google's deletion protection attribute which applies across all surfaces (UI, API, & Terraform). | <code>bool</code> | | <code>true</code> |
| [disk_autoresize_limit](variables.tf#L93) | The maximum size to which storage capacity can be automatically increased. The default value is 0, which specifies that there is no limit. | <code>number</code> | | <code>0</code> |
| [disk_size](variables.tf#L99) | Disk size in GB. Set to null to enable autoresize. | <code>number</code> | | <code>null</code> |
| [disk_type](variables.tf#L105) | The type of data disk: `PD_SSD` or `PD_HDD`. | <code>string</code> | | <code>"PD_SSD"</code> |
| [edition](variables.tf#L111) | The edition of the instance, can be ENTERPRISE or ENTERPRISE_PLUS. | <code>string</code> | | <code>"ENTERPRISE"</code> |
| [encryption_key_name](variables.tf#L117) | The full path to the encryption key used for the CMEK disk encryption of the primary instance. | <code>string</code> | | <code>null</code> |
| [maintenance_config](variables.tf#L146) | Set maintenance window configuration and maintenance deny period (up to 90 days). Date format: 'yyyy-mm-dd'. | <codetitle="object({ maintenance_window = optional(object({ day = number hour = number update_track = optional(string, null) }), null) deny_maintenance_period = optional(object({ start_date = string end_date = string start_time = optional(string, "00:00:00") }), null) })">object({…})</code> | | <code>{}</code> |
| [postgres_client_certificates](variables.tf#L207) | Map of cert keys connect to the application(s) using public IP. | <code>list(string)</code> | | <code>null</code> |
| [prefix](variables.tf#L213) | Optional prefix used to generate instance names. | <code>string</code> | | <code>null</code> |
| [replicas](variables.tf#L233) | Map of NAME=> {REGION, KMS_KEY} for additional read replicas. Set to null to disable replica creation. | <codetitle="map(object({ region = string encryption_key_name = string }))">map(object({…}))</code> | | <code>{}</code> |
| [root_password](variables.tf#L242) | Root password of the Cloud SQL instance. Required for MS SQL Server. | <code>string</code> | | <code>null</code> |
| [users](variables.tf#L253) | Map of users to create in the primary instance (and replicated to other replicas). For MySQL, anything after the first `@` (if present) will be used as the user's host. Set PASSWORD to null if you want to get an autogenerated password. The user types available are: 'BUILT_IN', 'CLOUD_IAM_USER' or 'CLOUD_IAM_SERVICE_ACCOUNT'. | <codetitle="map(object({ password = optional(string) type = optional(string) }))">map(object({…}))</code> | | <code>null</code> |
