google_sql_database_instance

Creates a new Google SQL Database Instance. For more information, see the official documentation, or the JSON API.

Example Usage

SQL First Generation

resource "google_sql_database_instance" "master" {
  name = "master-instance"
  database_version = "MYSQL_5_6"
  # First-generation instance regions are not the conventional
  # Google Compute Engine regions. See argument reference below.
  region = "us-central"

  settings {
    tier = "D0"
  }
}

SQL Second generation

resource "google_sql_database_instance" "master" {
  name = "master-instance"
  database_version = "POSTGRES_9_6"
  region = "us-central1"

  settings {
    # Second-generation instance tiers are based on the machine
    # type. See argument reference below.
    tier = "db-f1-micro"
  }
}

Argument Reference

The following arguments are supported:

  • region - (Required) The region the instance will sit in. Note, first-generation Cloud SQL instance regions do not line up with the Google Compute Engine (GCE) regions, and Cloud SQL is not available in all regions - choose from one of the options listed here. A valid region must be provided to use this resource. If a region is not provided in the resource definition, the provider region will be used instead, but this will be an apply-time error for all first-generation instances and for second-generation instances if the provider region is not supported with Cloud SQL. If you choose not to provide the region argument for this resource, make sure you understand this.

  • settings - (Required) The settings to use for the database. The configuration is detailed below.

  • database_version - (Optional, Default: MYSQL_5_6) The MySQL version to use. Can be MYSQL_5_6, MYSQL_5_7 or POSTGRES_9_6 for second-generation instances, or MYSQL_5_5 or MYSQL_5_6 for first-generation instances. See Second Generation Capabilities for more information. POSTGRES_9_6 support is in Beta.

  • name - (Optional, Computed) The name of the instance. If the name is left blank, Terraform will randomly generate one when the instance is first created. This is done because after a name is used, it cannot be reused for up to one week.

  • master_instance_name - (Optional) The name of the instance that will act as the master in the replication setup. Note, this requires the master to have binary_log_enabled set, as well as existing backups.

  • project - (Optional) The ID of the project in which the resource belongs. If it is not provided, the provider project is used.

  • replica_configuration - (Optional) The configuration for replication. The configuration is detailed below.

The required settings block supports:

  • tier - (Required) The machine tier (First Generation) or type (Second Generation) to use. See tiers for more details and supported versions. Postgres supports only shared-core machine types such as db-f1-micro, and custom machine types such as db-custom-2-13312. See the Custom Machine Type Documentation to learn about specifying custom machine types.

  • activation_policy - (Optional) This specifies when the instance should be active. Can be either ALWAYS, NEVER or ON_DEMAND.

  • authorized_gae_applications - (Optional) A list of Google App Engine (GAE) project names that are allowed to access this instance.

  • availability_type - (Optional) This specifies whether a PostgreSQL instance should be set up for high availability (REGIONAL) or single zone (ZONAL).

  • crash_safe_replication - (Optional) Specific to read instances, indicates when crash-safe replication flags are enabled.

  • disk_autoresize - (Optional, Second Generation, Default: true) Configuration to increase storage size automatically.

  • disk_size - (Optional, Second Generation, Default: 10) The size of data disk, in GB. Size of a running instance cannot be reduced but can be increased.

  • disk_type - (Optional, Second Generation, Default: PD_SSD) The type of data disk: PD_SSD or PD_HDD.

  • pricing_plan - (Optional, First Generation) Pricing plan for this instance, can be one of PER_USE or PACKAGE.

  • replication_type - (Optional) Replication type for this instance, can be one of ASYNCHRONOUS or SYNCHRONOUS.

  • user_labels - (Optional) A set of key/value user label pairs to assign to the instance.

The optional settings.database_flags sublist supports:

  • name - (Optional) Name of the flag.

  • value - (Optional) Value of the flag.

The optional settings.backup_configuration subblock supports:

  • binary_log_enabled - (Optional) True if binary logging is enabled. If logging is false, this must be as well.

  • enabled - (Optional) True if backup configuration is enabled.

  • start_time - (Optional) HH:MM format time indicating when backup configuration starts.

The optional settings.ip_configuration subblock supports:

  • ipv4_enabled - (Optional) True if the instance should be assigned an IP address. The IPv4 address cannot be disabled for Second Generation instances.

  • require_ssl - (Optional) True if mysqld should default to REQUIRE X509 for users connecting over IP.

The optional settings.ip_configuration.authorized_networks[] sublist supports:

  • expiration_time - (Optional) The RFC 3339 formatted date time string indicating when this whitelist expires.

  • name - (Optional) A name for this whitelist entry.

  • value - (Optional) A CIDR notation IPv4 or IPv6 address that is allowed to access this instance. Must be set even if other two attributes are not for the whitelist to become active.

The optional settings.location_preference subblock supports:

  • follow_gae_application - (Optional) A GAE application whose zone to remain in. Must be in the same region as this instance.

  • zone - (Optional) The preferred compute engine zone.

The optional settings.maintenance_window subblock for Second Generation instances declares a one-hour maintenance window when an Instance can automatically restart to apply updates. The maintenance window is specified in UTC time. It supports:

  • day - (Optional) Day of week (1-7), starting on Monday

  • hour - (Optional) Hour of day (0-23), ignored if day not set

  • update_track - (Optional) Receive updates earlier (canary) or later (stable)

The optional replica_configuration block must have master_instance_name set to work, cannot be updated, and supports:

  • ca_certificate - (Optional) PEM representation of the trusted CA's x509 certificate.

  • client_certificate - (Optional) PEM representation of the slave's x509 certificate.

  • client_key - (Optional) PEM representation of the slave's private key. The corresponding public key in encoded in the client_certificate.

  • connect_retry_interval - (Optional, Default: 60) The number of seconds between connect retries.

  • dump_file_path - (Optional) Path to a SQL file in GCS from which slave instances are created. Format is gs://bucket/filename.

  • failover_target - (Optional) Specifies if the replica is the failover target. If the field is set to true the replica will be designated as a failover replica. If the master instance fails, the replica instance will be promoted as the new master instance.

  • master_heartbeat_period - (Optional) Time in ms between replication heartbeats.

  • password - (Optional) Password for the replication connection.

  • sslCipher - (Optional) Permissible ciphers for use in SSL encryption.

  • username - (Optional) Username for replication connection.

  • verify_server_certificate - (Optional) True if the master's common name value is checked during the SSL handshake.
