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).
| [database_version](variables.tf#L50) | Database type and version to create. | <code>string</code> | ✓ | |
| [name](variables.tf#L91) | Name of primary replica. | <code>string</code> | ✓ | |
| [network](variables.tf#L96) | VPC self link where the instances will be deployed. Private Service Networking must be enabled and configured in this VPC. | <code>string</code> | ✓ | |
| [project_id](variables.tf#L107) | The ID of the project where this instances will be created. | <code>string</code> | ✓ | |
| [region](variables.tf#L112) | Region of the primary replica. | <code>string</code> | ✓ | |
| [tier](variables.tf#L123) | The machine type to use for the instances. | <code>string</code> | ✓ | |
| [authorized_networks](variables.tf#L17) | Map of NAME=>CIDR_RANGE to allow to connect to the database(s). | <code>map(string)</code> | | <code>null</code> |
| [availability_type](variables.tf#L23) | Availability type for the primary replica. Either `ZONAL` or `REGIONAL`. | <code>string</code> | | <code>"ZONAL"</code> |
| [backup_configuration](variables.tf#L29) | Backup settings for primary instance. Will be automatically enabled if using MySQL with one or more replicas. | <codetitle="object({ enabled = bool binary_log_enabled = bool start_time = string location = string log_retention_days = number retention_count = number })">object({…})</code> | | <codetitle="{ enabled = false binary_log_enabled = false start_time = "23:00" location = "EU" log_retention_days = 7 retention_count = 7 }">{…}</code> |
| [databases](variables.tf#L55) | Databases to create once the primary instance is created. | <code>list(string)</code> | | <code>null</code> |
| [labels](variables.tf#L85) | Labels to be attached to all instances. | <code>map(string)</code> | | <code>null</code> |
| [prefix](variables.tf#L101) | Prefix used to generate instance names. | <code>string</code> | | <code>null</code> |
| [replicas](variables.tf#L117) | Map of NAME=>REGION for additional read replicas. Set to null to disable replica creation. | <code>map(any)</code> | | <code>null</code> |
| [users](variables.tf#L128) | Map of users to create in the primary instance (and replicated to other replicas) in the format USER=>PASSWORD. For MySQL, anything afterr the first `@` (if persent) will be used as the user's host. Set PASSWORD to null if you want to get an autogenerated password. | <code>map(string)</code> | | <code>null</code> |
